using namespace std;
int multiply(int a, int b)
{
cout << a*b <<endl;
return 0;
}
int multiply(int a, int b, int c)
{
cout << a*b*c <<endl;
return 0;
}
int main()
{
//function with two arguments passed
multiply(3, 50);
//function with three arguments passed . It is different in number of arguments passed. Thus here function signature is different
multiply(4, 20, 10);
}
