    scanf("%d", &n);

    printf("Enter %d integers\n", n);

    for(c=1;c<=n; c++){

        scanf("%d", &value);

        sum= sum+value; /*adding each no in sum */

        sub= value-sub;

    }

    printf("Sum of entered Integers =%d\n", sum);

    printf("Difference  of entered Integers=%d\n", sub);
