Frequent Asked Questions (FAQ)
- What is Code Lab?
- Code Lab is an online compiler and lint tool which allows you to run, improve and share your code using several programming languages.
- Are there any memory or time constraints for the submitted programs?
- Yes, they are as follows:
- compilation time: 10 seconds
- execution time: 5 seconds
- memory usage: 256 MiB.
- Can I access the Internet from my program?
- No, access to the network is blocked.
- Can I write or read files in my program?
- Yes, but there is an 1 MiB limit of disk space.
- How long my codes will be stored on Code Lab?
- 6 months
- What is the size limit for the source code, input and output?
- 128 KiB
- What encoding is used in the source code and in the input stream?
- How is end of line (EOL) represented in the source code and in the input stream?
- End of line is represented by
\n (LF, Linux style). Even if you submit input or source code with Windows EOL (
\r\n, CRLF) or Mac OS EOL (
\r, CR), end-of-lines will be converted to the Linux style.

- Be sure to place "main" class/program/module/function/procedure in your code (here you will find a sample for every language).
- I would like to see a new language or library on Code Lab. Is there anything I can do about that?
- Yes, please contact us.
