Where can I code in C? I have an upcoming CS course in uni that uses C and I want to get ahead a little bit this Christmas break but I'm having a hard time figuring out where I can actually code using C. My school uses this compiler called Seashell but it's not available until the term starts.

I've looked at visual studio but I only see C++, and I've heard of stuff like Vim, GCC, but I'm pretty new to CS and I don't know what any of that really means...

Help?
Visual Studio Code
Supports many languages including C/C++. It's a very simple IDE. Have a look at it.
