Thread: Passing info to main

I have a simple function :

Code:

void Age_Class::enter_info ()
    {
     cout << " Enter your age" << endl;
     cin >> age
   }

I would like to send the info (age) to the main block for calculation, how can I do that

I had

return age;

in the function. but I get errors, what is the proper way to return it.

I ran to a similar problem with a different project. Here is part of the code:

Code:

// get_monthly_total Functions - calculates the total bill
// Standard Plan Class
void Standard_Plan_Class::get_monthly_total ()
     {
      // Local Variables
       double payment = 20.00;      // Basic Monthly Payment -> $ 20
       double extra_hours;             // Extra hours over the 20h monthly limit
       double over;                         // # of Extra Hours over 20h limit * 50 cents each
  
       if (hours_online > 20)
         {
           // Monthly Bill Calculation
           extra_hours = hours_online - 20;
           over = extra_hours * .50;
           total = payment + over;
         }
          else
               {
                  total = payment;
               }
     }





// calculation Functions - gets "total" amount from get_monthly_total
double Standard_Plan_Class::calculation ()
      {
       return total ;
      }




// pc_output Functions - display information to the user
// Standard Plan Class
void Standard_Plan_Class::pc_output ()
   {
      cout << "Your total monthly payment is: $ " << calculation () << endl;
   }

The problem is that no matter what number I type in (hours_online) the total monthly payment always comes out to 0.00.

What is causing this problem ?
