               Printf(“enter first no :”); /*user will define the value*/
               Scanf(“%d”&a);
               Printf(“enter second first no :”);
               Scanf(“%d”&b); /*user will define the value*/
               a=a+b;
               b=a-b;
               a=a-b;
               printf(“%d”,a);
