Nothing special happening in the files listed around the first XXXX total.. Lots of separate bits that you join together. I have a really long line of code and i was wondering what the syntax is so that i could have it on multiple lines, for easier readibility. One day the head of QA came to me, screaming. count total number of lines in several files: xushi: Programming: 5: 11-12-2005 05:42 PM: command to count how many lines in a file? But when the difference is much smaller, why bother using lines as an indicator of anything? 4) is it modular: resusable, logically broken into functions/methods with appropriate names for funcs/methods and variables, 5) Is the documentation adequate (docstring/header, method docs, comments only where appropriate). While the Linux open source operating spans 15 million lines of code across 40,000 software files, Google engineers modify 15 million lines of code across 250,000 files each week. Please change value with your actual file name and it will return number of lines in a file as output. I continued "... but then the code would be much more complex." It's part preference, part performance. https://cseducators.stackexchange.com/questions/3339/how-many-lines-does-your-code-have/3351#3351, https://cseducators.stackexchange.com/questions/3339/how-many-lines-does-your-code-have/6275#6275, https://cseducators.stackexchange.com/questions/3339/how-many-lines-does-your-code-have/6284#6284. So I have a file that has seven lines of text and I have to count them. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy, 2020 Stack Exchange, Inc. user contributions under cc by-sa. Even looking for outliers is throught with dangers. This is a sample file to get line numbers from the file. Because they knew how many line it should take, and they were looking for statistical outliers. Some one introduced a software metrics tool. Media. Because they knew how many line it should take, and they were looking for statistical outliers. Its just another way of valuation. It only takes seconds to count the LOC in a project. When I was an university, there was a myth that some lazy teachers (I don't know the technical terms for the roles), would weigh your reports, and give a grade base on that. In any case, I could not count lines of code. In the programming industry I have noticed an odd trend among certain programmers that go through great lengths to make their code as terse as possible. Do let me know in the comments section if you have any doubts. I also tried piping into a file like @funilrys did it, but the output was the same You can also count number of line on piped output. However, the console shows a large file list, then 150017 total, then again a large file list and then 38491 total.Somehow, the result is divided into several bins but I cannot figure out why. and introspection began. Variables are short, each line is crammed with as many instructions as possible, etc. And we don't know anything about how the teacher intended to use the answer. A few years back, when I was a software engineer. It gives us an ongoing indicator as to when things might need to be broken down into smaller parts or refactored a bit. Click here to upload your image New media New comments Search media. The scenario here doesn't really give much context for the evaluator's question. There is nothing worse when doing an interview than asking an opening question which your student doesn't understand well enough even to be able to guess the answer. This tool will return the number of lines detected in a text. The most direct way to count lines of code (LOC) is to, well, count lines of code. Its the same concept as in reports. “But what about Jane?” I said. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. Forums. as the delimiter but I tried it with the \n and it would always return as 0. One response to “Count the number of lines in a text file … If our student was really clever and wanted to implement that in Python 2, they could have just written input().encode('rot13'). 100 lines of Perl will probably accomplish a lot more than 100 lines of C. So you have to be careful that you're really comparing apples to apples. It was a good tool. LoC can be useful for spotting really badly wrong solutions, but setting 'targets' with it can be harmful. How many lines of code are there in Windows? This is the only one that would make any sense, but people do a lot of thinks that don't make sense. What you should aim for is code without unnecessary complexity, not a certain maximum line count. Is a million lines of code a lot? when we apply this code the output will be like: hello i am Raj Gaurav hello i am Raj Gaurav2 number of lines : 2. Facebook? In any case, I could not count lines of code. He was waving a bit of paper with the results of the tests. This question was prompted by observing a faculty member in projects evaluation. It measured Mccabe complexity (various complexities of the code). out they weren't really difficult at all. This program will open a file and read the file’s content character by character and finally return the total number of lines in the file. On the other hand, a common mistake made by novice programmers is to write a routine, then copy and paste it and make a few small changes to it. That's not how character encodings work in reality (there's an offset in ASCII before you get to the capital letters), but it's not relevant for the example. Following command will count number of lines in /etc/passwd files and print on terminal. Why does the number of lines in the project matter all that much? Please show some significant part of the code and explain it to me. I will include the last 3 paragraphs here. A SmartBear study of a Cisco Systems programming team revealed that developers should review no more than 200 to 400 lines of code (LOC) at a time. Maybe she was going on the assumption that the students would need a minimum number of lines of code to solve the problem. Did you know? Sometimes called "copy pasta" this is a poor programming practice because it results in code that is redundant and the same bug can appear in many places in the code.

Of course the simple line of code check doesn't catch either of these situations, there are automatic ways of trying to detect code quality but they are much more complex and subjective. So I need to know how important this question is and is it really worth asking the nervous students who have just arrived to present their full projects rather than a routine programming assignment? It’s a useful metric to have: a quick way to see how long a given method is or object has. This has the convenient property of being self-inverse, so you don't need to subtract to decrypt in a separate function. I got the picture clearly. She hasn't really proved herself yet — if you see So the point is not the factual information by itself. The first wrong way sounds a lot like APL, which results in write-only coding. Most importantly, we have no information about what she did as a result of the opening question. “I thought Jane was Also read how to find total words in a string. Chances are we have a feel for when things are getting too long, but seeing an ongoing count on the side of the screen often helps. I'm surprised that you didn't ask this teacher why she asked this question and how it fits into her overall evaluation. To count the number of lines we will check the available Newline (\n) characters. If you can define 'worth asking', this question would be better. Lets say the lab manual has about 30 lines for the bubble sort implementation. By asking a 'harmless' question which has no right answer, it makes the rest of the questions much easier to pitch. Home. For one thing, different languages vary widely in the number of lines of code they produce. We stopped using the tool shortly after that. ±¾Õíîl¿x¾½qÞd A shame. I've heard of one example where some students were set the task of creating a Caesar cipher1 program. Faster than asking. Example. Usage: lines [directory] $ lines Found 562 lines of text in . pretty simple. Let our data-visualization program your brain. “Jane came to us with a great reputation. This program correctly counts the correct amount of lines of text if I use the . Wait a minute! Moreover, you don't say how accurate the teacher expected the answer to be. Other than that, I cannot imagine how this question really helps much with anything. thought were going to be really tough, but when she finished it turned If the line count is way off then it is a sign of a problem. Description: Running the FIND command with option /v and empty search string will find all lines Running the FIND command with option /c will output the line count only. Hopefully, students are writing clear, maintainable code, not playing code golf, so a longer, explicit solution may actually be better. Equally, treating a higher LoC measurement as a better project is a bad idea. iPhone apps? really proved herself yet. (out/err)" should not be used to log messages; Overriding virtual functions should not change parameter defaults; Starting with the subject, such as "Files", will ensure that all rules applying to files will be grouped together. You can also provide a link from the web. I agree with the other posters here: using num LoC as an indicator is a very poor assessment of the code. So yes lines of code can be useful, but only as a statistical tool. The results of applying these tools to 2008's Fedora 9 Linux came out to a total of 204,500,946 physical SLOC (Source Lines of Code) and a cost of $10,784,484,309. There is no right answer here. -- He looked at me blackly. Programs like this would have far fewer lines of code than average but be of poor quality. Restructuring and refactoring code can be tricky and time consuming and when programmers get in a hurry they sometimes just copy paste. We can speculate on situations in which it might be a good question and we can speculate on situations in which it might be a terrible question, but we can't know unless we know why it was asked. I have, myself, asked students at the beginning of a project to tell me how big their self-defined project will be using various measures. The point is starting an interview with a nervous student, about a project of some size. Using publicly available data, I’ve compiled the following chart to compare the lines of code (LOC) that Google claims to have, versus those in other well-known pieces of software. Also read how to create a Text file, Open and Read: File Handling. It told us what the probably bug density is, if you knew how to read it. Not a 20 lines exercise for which an interview with each student is a waste of time. My guess is that the question is primarily intended to catch the outliers, those projects with a lot less or more code than average. My personal preference is to create a symbolic link between lines and /usr/bin/lines. Some of the other answers here provide such speculation. Before asking anything else, the very first question she asked from every student was: "How many lines does your code have?". I am reminded of the joke Abraham Lincoln told: ", https://cseducators.stackexchange.com/questions/3339/how-many-lines-does-your-code-have/3344#3344, https://cseducators.stackexchange.com/questions/3339/how-many-lines-does-your-code-have/3345#3345, https://cseducators.stackexchange.com/questions/3339/how-many-lines-does-your-code-have/3352#3352. As others have noted, the simple lines of code doesn't always have a lot of meaning in terms of the project's quality. An illustration depicts how many lines of code have been written to create the software and services. That sounds especially stupid until you know that my only goal was to get them to start to think about estimation, which they had never done. It was a good tool, and very useful. Most of them turned out Leaving out exceptionally talented students, most students would have at least 30 lines, and if they don't they probably haven't written the code. No difference, except in … Files using ASCII (in Python 2) or UTF-8 (in Python 3) should not have an encoding declaration. Summary. I pointed out that all the other complexity metrics were close to zero. It showed that a module, that I had written had a complexity for class dependency that was off the chart. Less lines of code does not always mean more efficient. Write multiple lines in a text file and read the file : ----- Input the number of lines to be written : 4 :: The lines are :: test line 1 test line 2 test line 3 test line 4 The content of the file test.txt is : test line 1 test line 2 test line 3 test line 4 Flowchart: C Programming Code Editor: It is perfectly possible that this opening was a hidden request for context - is the presenter actually familiar with the code or just doing the PR part of the project? You could find parts of the code that were un-usual. However it did not tell us where the bugs were. I remember a story by Michael Jackson, about judging how brilliant some one is. Faculties will ask you to write 2 pages, but what if the content only merits 1 page or 4? Thank you! Š~¸ªoUöúöÖvmÚ󝆲—Ôým That code assumes that all the letters you want to encode are encoded from 0 to 25 (e.g. The brain can only effectively process so much information at a time; beyond 400 LOC, the ability to find defects diminishes. In practice, a review of 200-400 LOC over 60 to 90 minutes should yield 70-90% defect discovery. I don't think anyone can answer this question without more information. @Gilles She was asking them to answer it precisely to the .. say 673 lines of code and they had a computer with source code in it but this question was asked during project evaluation. P.S: While I am neither in favour nor against this question but I have been coding since 2009/10 and my personal experience reminds me that I still don't remember the lines of code for even my own freelancing softwares (even for my thesis program - by don't remembering I mean I even don't remember whether it was 1200 lines or 1800 lines). Menu. Often you could find bugs by examining these parts of the code. lost , Oct 20, 2005 mcfox Wind Maker New posts New media New media comments New resources New profile posts Latest activity. The American teletypewriters could type only 72 CPL, while the British ones even less, 70 CPL. “Terrific,” I mumbled respectfully. It helped us find bugs. as Frankenstein, Fred the brilliant creator of the uncontrollable 2There's a bit of a lie-to-children here, if you're not paying attention. I've even written console apps in notepad, and compiled from the command line with more lines than that, because I thought they were so small they didn't need a whole .sln and .proj file, and yet here is 37signals going live with a product that is just 579 lines of Ruby. Latest reviews Search resources. You could have 1000 very small files with < 300 lines or 100 larger files with 3000 lines. What's new. Even looking for outliers is throught with dangers. Using regular expressions may be pretty cool, but can make it very difficult to read for anyone that has to do maintenance on the code, or even to understand. Asking for the length directly is probably pointless—instead, just take a look at that when you review the code and mark it. regex can be readable. òdI^îAC}q&I§ÏŠ)÷j×Ê\ƒµxA{2ŸDòÉ @WŸ\´õbn®K‘/sµ] Ôv5Þ8. It's a whole new world up here! The limit of the line length in 70–80 characters may well have originated from various technical limitations of various equipment. Number of lines: 1. If the line count is way off then it is a sign of a problem. Did you know that the end line character is different based on the operating system: Unix, Linux, Mac OS X LF (\n) character is used (0x0A) Mac OS up to 9 (max 2 MiB). My current project has more lines of configuration than that. 1You might also know a variant of this as the ROT13 cipher where the shift is 13. 3) Has it followed the correct conventions? How many lines of code? … Spacing, layout, indentation etc. wc -l /etc/passwd . Before opening it, tell me how many lines does it have? 0 = A, 1 = B). If you do that, you're encouraging unnecessarily verbose solutions, like our student who wrote 1400 lines for a 5 line problem. Output: Total number of lines are: 2 Explanation. We can also use –lines in place of -l as command line switch. very good. Programs like this would have far more lines of code than average but be of poor quality. How it works. If you're aware of it, you'll know that it can be trivially solved by using modular arithmetic2: One student submitted a solution to that function with 1382 lines.3. So now you can see the merits of using code length to spot solutions that are over 250x longer than necessary. Google leads the list with staggering 2,000,000,000 lines of code. Some constructs such as "comprehensions", streams, lambdas or map/reduce allow you to pack a lot of complexity into a few lines. monster flowchart. Resources. I'd hope you remember the difference between 50 LOC and 50k though... Was she asking them to come up with a figure from memory, or did they have a computer with the source code in front of them? But some work requires writing 500 to 1000 lines. We thought she was going to be as brilliant as Fred. A few years back, when I was a software engineer. The barcode has a long and interesting history from its initial development nearly 70 years ago through today. Long files tend to indicate that methods, subroutines or classes are overly complex (doing too many things, not sufficiently factored, etc) E.g. Until we get a … Our goal with code should be to write 300 lines of clean code. He screamed, "but what about this one". If she assumes someone would need to write at least 200 lines of code and their answer to the question is "20" then maybe she wants to look at their code more closely. That’s 14x the length of War and Peace. But she hasn't I suppose you'd quickly realise that this student's solution was... sub-optimal... if you asked them how many lines when they presented their project. I heard of one student that handed in some work with a load of blank paper attached, and got a good grade. Unless the code is extraordinarily long or short (i.e. Unless the student is some kind of an expert already, lines of code will be a easy way to filter out those who have no idea what they are doing. And expected to be widely divergent from the earlier estimate, of course, since this was their first attempt. Fred Students of the Code.org tutorials (Code Studio) have written 24,705,279,321 lines of code.Is this a lot? orders of magnitude away from what is expected), lines of code aren't a good indicator of whether a project is good or bad. Over complex code is bad, see in working out the final grade, the number of lines of code, goes some ware in the denominator. A million lines of code, if printed, would be about 18,000 pages of text. The numbers they gave weren't a goal for the project, but only a source of reflection at the end. I said "if it was spread about, then the metrics would not find it, ..." he interrupted "then spread it about". She picked up the program design ideas very fast.”, “Yes,” said the DP Manager. Files should not have too many lines of code "System. So at the end, such a question would be completely natural and expected. File and line lengths are measurements of secondary effects of complexity and as such are highly variable. what I mean?”. By comparison, the Microsoft Windows operating system has roughly 50 million lines of code. As developers, we want to write "Lord of The Rings". Finally after file has reached end increment words and lines count by one if total characters > 0 to make sure you count last word and line. New posts Search forums. I disappointingly found that a lot of extensions, such as “.c”, are not included in the list of file extensions that should have their number of lines counted. We've given her a few problems that we Program to count characters, words and lines in a file /** * C program to count number of characters, words and lines in a text file. 3I cheated and calculated the amount of lines you'd use from that approach, rather than actually writing the whole thing and counting the lines. Just an interesting fact to know, how many lines of code are there, devs? $ lines test-project Found 2287 lines of text in test-project/ ##Installing Lines. The FOR command with option /f will parse the output, the line count in this case, and the set command put the line … This results in code that takes up the minimum of space but is often hard for humans to interpret, as if the programmer forgets that humans look at code as often as computers do. After you open it for the first time you my want to go to the Options -> Preferences and add all the extensions you typically write code in. Her question was normally: Now come to the code..
