Swaping Without 3rd variable

#include<stdio.h>

main()
{
    int a,b;
    printf("Enter a\n");
    scanf("%d",&a);
    printf("Enter b\n");
    scanf("%d",&b);
    printf("The values of a is %d and b is %d before swaping\n",a,b);
    a=a+b;
    b=a-b;
    a=a-b;
    printf("The values of a is %d and b is %d after swaping\n",a,b);

}

     

           

Note: Need to be arranged in compiler after copied

   

 OutPut:

Enter a 2 Enter b 3 The values of a is 2 and b is 3 before swaping The values of a is 3 and b is 2 after swaping
