Passing array to a function (and why it does not work in C++)

Question

I have come across some C code that compiles, but I do not understand why. Specifically, I have a C library that has a lot of code using this format:

void ge         


        

Answer 1

regarding the second part of your question:

Why doesn't the same version work in C++? When I literally change the file extension from .c to .cpp and try to recompile, I get

The source of that problem is that C++ mangles names.

To avoid name mangling when running C++ and trying to access a C library.

near the top of the header file for the C library, after the multiple inclusion guard insert:

#ifdef __cplusplus
extern "C" {
#endif

and near the end of the header file, before the #endif of the multiple inclusion guard, insert:

#ifdef __cplusplus
}
#endif

That will eliminate the problem of functions in the assocated library file not being found
