Thread: Passing a variable in void to another void function

Ok, so in my first void, the user inputs 4 numbers via a looping statement. In the next void statement, it is supposed to add these four numbers up and print them on screen. We are currently on structures/classes but I'm not sure how to print the summed up number in another void statement.

Code:

void Salesperson :: getsales ()
{
   double revenue; 

   for ( int i = 1; i <= 4; i++ ) 
   {
      cout << "Enter sales for quarter " << i << ": ";
      cin >> revenue;
      setsales( i, revenue);

   } // end for

}

As you can see, here is were the user inputs the four numbers. I am not sure if the numbers are added here as well or if they are added in the next void statement.

here is where the function is passed to, but i'm not sure if it is right:
[code]
void Salesperson :: setsales (int quarternum, double amount)
{
// test for valid month and amount values
double amount = 0.0; // initialize total

if
( quarternum >= 1 && quarternum <= 4 && amount > 0 )
sales[ quarternum - 1 ] = amount ;

else
cout << "Invalid month or sales figure" << endl;
for ( int i = 0; i < 4; i++ ) // summarize sales results
amount += sales[ i ];

}
Here is my setsales funtion.
my next void function is basically:

Code:

void printsales( )
{
   cout << "\nThe total annual sales are: $" << amount;
}

My prof gave me a hint and said, "stores all variables in your class" What does that mean?

Assuming you know the difference between a class and an object..
He means that the variables need to be inside the Salesperson class declaration. This means that every Salesperson object you create in your program will have their own unique data for values such as the number of sales achieved.

Judging by what you've said, Your Salesperson class probably should have a member variable which holds the sum of all the sales, or otherwise some kind of container or array which holds the sales individually for each quarter.
