#include<stdio.h>
void main()
    {
    int a,b;
    printf ("Enter the value of A:- ");
    scanf ("%d",&a);
    printf ("Enter the value of B:- ");
    scanf ("%d",&b);
    printf("%d is A and %d is B\n",a,b);
    a=a+b;
    b=a-b;
    a=a-b;
    printf("%d is A and %d is B\n",a,b);
    }

Let 4(a) 6(b)
4(a) + 6(b) = 10(a New)
10(a New) - 6(b) = 4(b New)
10(a New) - 4(b New) = 6(a New)

I expect you understand the code above.
