Question

I am a student and want to test my amerature C code online at any computer. There is a fantastic website http://www.codepad.org that i use. My only problem is that it wont let me input things using scanf and it wont let me -lm. Is there a website that allows these things?

Answer 1

Then why don’t you get a free shell account? So long as you are active, and don’t break the rules, it’s there for you.

Google for lots of other choices, if your provider goes up and down. Use git to keep a local copy of your code synchronized between all of your different shell accts and provide a backup. You can even push to github.

This will also give you the opportunity to use and learn about a bunch of useful and important tools:

• ssh/mosh
• vim/emacs
• bash (don’t forget process control!)
• gdb or cgdb
• tmux/screen
• python/perl/shell scripts
• make

I wish that my college classes had gone over at least some of these before I finished my degree…
