Is Visual Studio the best for creating apps in C?

Question

If not, what do you suggest?

Answer 1

That's hard to answer because editors are highly subjective. I personally don't like using IDEs, for me they're added complexity and often very slow, but if you find them useful then stick with it.
The MSVC compiler is quite dated and MS have no plans to extend its features beyond what they can backport from their C++ compiler, so for pure C applications you're limited to a weird mix of C89 and C99 features. (C89 = No inline keyword, no designated initializers, no compound literals, no convenient way of printing sizes/addresses, no offsetof() operator or long long types, etc).
If you want to make C programs in Windows, I would recommend installing GCC with MinGW/Cygwin. Or use a C subset of C++ and compile with the MSVC++ compiler.
