    Functions

    Based on : Cprogramming.com Tutorial: Functions

    Code:
    #include <iostream>
    
    using namespace std;
    
    int mult ( int x, int y );
    
    int main()
    {
      int x;
      int y;
      
      cout<<"Please input two numbers to be multiplied: ";
      cin>> x >> y;
      cin.ignore();
      cout<<"The product of your two numbers is "<< mult ( x, y ) <<"\n";
      cin.get();
    }
    
    int mult ( int x, int y )
    {
      return x * y;
    }
    Can't understand whats the point of using the int mult ( int x, int y ) instead of

    Code:
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
      int x;
      int y;
      
      cout<<"Please input two numbers to be multiplied: ";
      cin>> x >> y;
      cin.ignore();
      cout<<"The product of your two numbers is "<< (x * y) <<"\n";
      cin.get();
    }
    Need some explanation on whats the point of using int mult ( int x , int y ) and hopefully some example on where they use it on. Thanks in advance

    There is no point other than to demonstrate a very simple function.

"Finding the smallest program that demonstrates the error" is a powerful debugging tool.
