Function Overloading in Functions in C++

 int sum(int a , int b) {

    cout << (a+b) << endl;

    return a + b;

}

double sum(double a, double b) {

    cout << (a+b) << endl;

    return a + b;

}

int sum(int a, int b, int c){

    cout << (a+b+c) << endl;

    return a + b+ c;

}

int main(){

    sum(2,3);

    sum(12, 13);

    sum(1.5, 2.5); //  4

    sum(1,2,3);

    return 0;

}
