#include<stdio.h> ( this applies in the given code )
#include
int main()
{
int a,b;
printf(“Enter Value of a :”);
scanf(“%d”,&a);
printf(“Enter Value of b :”);
scanf(“%d”,&b);
a=a+b;
b=a-b;
a=a-b;
printf(“\nAfter Swapping Values a = %d b = %d”,a,b);
return 0;
}
OUTPUT
Enter Value of a :5
Enter Value of b :4
After Swapping Values a = 4 b = 5
