Function Prototypes in C and C++ - ThoughtCo

WebbIn C language function prototype is used to provide function declaration. It defines the function's name, returns types, and parameters. The return types are the data types that the function returns after execution. If a function returns an integer, the return type is int. When a function returns a float value, the return type is also a float. http://www.trytoprogram.com/cplusplus-programming/functions/ storm storys all episodes
