Question 11 :

When we mention the prototype of a function?

A). Defining
B). Declaring
C). Prototyping
D). Calling
Answer : Option B

Explanation :

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.
