Hi, since se code is giving me a lot of problems regarding txt files I wanted to give it a go. Does the ide have problems with relative paths end reading/writing in a txt file?
The program should be able to inizialize variables by reading the file at the start.

Thanks

OnlineGDB runs on a remote server, and the result is forwarded to your local PC (browser). File operations work fine as long as you do not try to poke around where you do not belong, e.g., try to leave your projects directory.
