How many lines of code do software engineers write per day?

The table below shows the results of our calculations, which, again, are based on educated guesses. As we can see, a new developer will probably write about 100 lines of code a day, or about 25,000 lines of code in a given working year.

How many lines of code are in a big project?

Diseconomies of Scale and Lines of Code

How many lines of code are there in software?

12-15 million lines
The Android operating system runs on 12-15 million lines. The Large Hadron Collider uses 50 million lines. Not including backend code, Facebook runs on 62 million lines of code.

Is 1000 lines of code too much?

Lines of source code is a very, very crude measure of program size and complexity. It’s also the most common. To a very rough approximation, it can be used, but don’t take it as gospel. So 1000 lines is a small project, personal or otherwise.

How many lines of code per day is good?

You can have a good day and write 1000 lines of code, but on average you will have less than 100. Once you are working a product which is more mature, you will only change as little lines as possible so it might 10 lines per day, or even 1 line per day on average.

Is 10000 lines of code a big project?

10k is considered a medium project: it is not something that you write in a week, but certainly feasible in a year (complexity is not linear in lines of code).

What is lines of code in software engineering?

Source lines of code (SLOC), also known as lines of code (LOC), is a software metric used to measure the size of a computer program by counting the number of lines in the text of the program’s source code.

How do you count lines of code?

Cloc can be used to count lines in particular file or in multiple files within directory. To use cloc simply type cloc followed by the file or directory which you wish to examine. Now lets run cloc on it. As you can see it counted the number of files, blank lines, comments and lines of code.

How many lines of code is Google?

2 Billion Lines
Google Is 2 Billion Lines of Code—And It’s All in One Place. By comparison, Microsoft Windows—one of the most complex software tools ever built for a single computer—is about 50 million lines. How big is Google?

How many lines of code does a typical software developer code per day?

In the software that runs the Space Shuttle, developers average < 5 lines of code per day (1163 lines/man-year). On the project I currently work on, developers average > 80 lines per day (but it varies a lot over time: sometimes it’s near zero, other times it’s several hundred).

How many lines of code do you write in a day?

As usual it all depends, but on average between 200-250 lines of code in a very productive day. It is not distributed even. Eg. In one day you might be writing 500 lines of code, and the next, 3-4 lines and small changes on just fixing bugs from the previous day, (that stuff takes a lot of time too).

Why does it take so long to test a change in code?

If it’s hard to run this code for whatever reason (internal state of the code, the project is on the cutting edge of some deep cutting edge hardware, or the codebase is just big ), it may take some time to launch the app to test the change.

What are the factors that affect the amount of code written?

1. Length and frequency of meetings. If you engineers spend half their time in meetings, less code gets written 2. How good the given specs for a piece of work are. I’ve been in situations where I’ve spent 2-3 hours working with a business person to understand the business problem I need to solve with this code I’m working on.
