 When you want to use a language that gets compiled and runs at high

-C has one other advantage over C++ and other compiled languages: more
-people know C, so more people will find it easy to read and modify the
-program if it is written in C.

-So in general it is much better to use C, rather than the

-But there are two exceptions to that conclusion:
