C Programming - Declarations and Initializations


When we mention the prototype of a function?

A. Defining
B. Declaring
C. Prototyping
D. Calling

Answer: Option B


A function prototype in C or C++ is a declaration of a function that omits the function body but does specify the function's name, argument types and return type.

While a function definition specifies what a function does, a function prototype can be thought of as specifying its interface.
