The keyword used to transfer control from a function back to the calling function is
Answer: Option
Explanation:
The keyword return is used to transfer control from a function back to the calling function.
Example:
#include<stdio.h>
int add(int, int); /* Function prototype */
int main()
{
int a = 4, b = 3, c;
c = add(a, b);
printf("c = %d\n", c);
return 0;
}
int add(int a, int b)
{
/* returns the value and control back to main() function */
return (a+b);
}
Output:
c = 7

Prototype should be given after the header file inclusion and before the main() function.
Using this we says to the compiler that 'that specific name'(ex. Fun()) will come in my program. ie it is nothing but pre declaration of that'fun' function.
There are three states of function:-
1). we declare prototype as- void fun(int,int); //compulsory to give semicolon
2). we call function as- fun(int,int) ; //no need to write return type of function
3). we define function as- void fun(int i, int j)
{
//code
}
