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

Relation between main function and called function is called "PROTOTYPE".
EX:- int add(int, int); /* Function prototype */
EX:- int add(int, int); /* Function prototype */

Tell me the difference between printf (predefined function) and return (keyword).

We cannot write two arguments in the return statements
ex:
return(x,y);
it will take only 3
ex:
return(x,y);
it will take only 3

0 is beside return because the function is integer type it should return integer value.

@Rathika
a=1
a++=1 //it increment the value after execute the exp
++a=3 //it increment the value before execute the exp
a=1
a++=1 //it increment the value after execute the exp
++a=3 //it increment the value before execute the exp

Please say what is the output of this program?
#include<stdio.h>
#include<conio.h>
void main()
{
int a=1;
printf("\n %d %d %d",a,a++,++a);
getch();
}
#include<stdio.h>
#include<conio.h>
void main()
{
int a=1;
printf("\n %d %d %d",a,a++,++a);
getch();

In simple way, return is a c-keyword used to transfer the control from called function to calling function. It can also use for return a single value.
