Explanation:

Function declaration are called prototype, since they provide a model or blueprint for the function.

The Function prototype provides the following information about a function to be called –

• It tells about the return type of the function .

• Prototype tells the number of arguments should be passed to the function.

• It gives the information about the data types of each of the passed arguments.

• we get information about the order in which the arguments are passed to the function.

• The function prototype specifies  what should be given  to the function and what to expect from the function.

• The prototype of a function is also known as the signature of the function.
