Показать описание
Function Prototypes : They are useful for allowing functions to be used before they are defined, and for ensuring that functions are being used correctly by the compiler.

In C programming, a function prototype is a declaration of a function that specifies its name, return type, and parameters without actually defining the body of the function.

Function prototypes are typically placed at the beginning of a program or in a header file so that other parts of the program can use the function before it is defined. This is useful when you have multiple functions that call each other, or when you want to separate the interface of a function from its implementation.
