#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)
