C Program for Swapping using call by value method

C Program for Swapping using call by value method

Program:-        

#include <stdio.h>

#include<conio.h>

void swap(int, int);

int main()

{

int x, y;

printf("Enter the value of x and y\n");

scanf("%d %d", &x, &y);  

printf("Before Swapping x = %d y = %d\n", x, y);

swap(x, y);    

printf("After Swapping  x = %d  y = %d\n", x, y);

return 0;

}

void swap(int a,  int b)

{

int temp;   

temp = b;

b = a;

a = temp;

printf("Values of a and b is %d  %d\n", a, b);

}

Output:-

Enter the value of x and y : 4  6

Before Swapping x = 4 y =6

After Swapping  x = 6 y = 4
