Question

Function prototypes and function definitions look similar because they have the same function heading. In a function prototype the heading is followed by a ___, whereas in a function definition the heading is followed by a ___.

Answer 1

In a function prototype the heading is followed by a semicolon, whereas in a function definition the heading is followed by a function block.

Step-by-step explanation:

As the function prototype only declares the function and the function definition defines the operations in the function.

e.g:

add(int x, int y); is the prototype

add(int x, int y)

{

int sum;

sum
`=` x
`+`y;

} is the function definition.
