Function prototyping is the declaration of a function's signature or interface before its actual definition. It tells the compiler about the existence of a function, its name, return type, and the number and types of its parameters. Function prototyping is essential in C and C++ programming languages to enable the compiler to perform type-checking and generate correct function calls.
The function prototype typically appears at the beginning of the source code or in a header file before the main program or any code that calls the function. It consists of the function's name, return type, and a list of parameter types. The actual function definition, which contains the implementation of the function, may appear later in the code.
The syntax for function prototyping is as follows:
return_type function_name(parameter1_type parameter1_name, parameter2_type parameter2_name, ...);
