(3). With argument- without return:-
In this type, function takes argument but does not return any value.
#include<stdio.h>
void sum(int,int);
int main()
{
int a,b;
printf("Enter the value of a and b");
scanf("%d%d",&a,&b);
sum(a,b); // function calling
return 0;
}
// End of main function
// function definition of sum
void sum(int x,int y)
//where x and y are formal argument
{
int z;
z=x+y;
printf("sum of a and b is %d",z);
}
output:-
Enter the value of a and b
10 5
sum is 15
(4). without argument- without return:-
In this type, function does not takes any argument and does not return any value.
#include<stdio.h>
// Global declaration of sum
void sum(void);
int main()
{
sum(); // function calling
return 0;
}
// End of main function
// function definition of sum
void sum(void)
//where x and y are formal argument
{
int x,y,z;
printf("Enter the value of x and y");
scanf("%d%d",&x,&y);
z=x+y;
printf("sum of %d and %d is %d",x,y,z);
}
output:-
Enter the value of x and y
10 5
sum of 10 and 5 is 15
