When function prototype is not necessary in c++?
I have a question about c++. When is function prototype not necessary in c++?
Function prototypes are necessary in C++ to allow the compiler to know about the function before it is defined or called. However, in certain cases, function prototypes may not be necessary. For example, if the function is defined before the main function, or if the function is only ever called in the same file where it is defined.
