I feel dumb for not knowing this, but I was under the impression that today’s Visual Studio only built things like C#, C++, etc. — since those are the things listed when you make a new project.
I happened to ask ChatGPT about building C in Studio, and it told me I could just make C++ project and save the file out as a .c and get a C project. I had no idea.
Though, it’s many more steps to do this than, say, popping out to https://www.onlinegdb.com/online_c_compiler, just to do a quick test, but it’s useful.
I have only tried this under Windows, but I plan to see if the Mac version of Visual Studio supports the same. I’ve tried to get C code building in VS Code, but it’s klunky (makefiles!).
