void largestNum(int a, int b, int c) {

    if(a > b && a > c) {

        cout << a << " : A is greater than B and C";

    } else if(b > a && b > c) {

        cout << b << " : B is greater than A and C";

    } else {

        cout << c << " : C is greater than B and A";

    }  

}

int main(){

    largestNum(12, 8, 6);
