modifying a program so it uses a program defined function to get and validate sales.

I need to modify this program so that it uses a value-returning function to get and validate the sales amount entered by the user. The function should return a value such as Y or N that indicates if the sales amount is valid.  The return value should determine whether to calculate and display the commission.  My problem is when I enter a negative number as the sales it returns a negative commission instead of the "No commission calculated" message.

//T9AppE10.cpp - displays the commission

#include <iostream>
using namespace std;

//function prototype
float calcCommission(int);
int getAndValidateSales(int);

int main()
      int sales        = 0;
      float commission = 0.0;
      int salesData = 0;
      //enter input data
      cout << "Enter sales: ";
      cin >> sales;

      //validate input data
      if (salesData = 1)
            //calculate and display commission
            commission = calcCommission(sales);
            cout << "Commission: " << commission << endl;
            cout << "No commission calculated" << endl;
      //end if

      return 0;
}   //end of main function

//*****program-defined functions*****
float calcCommission(int amountSold)
      //calculates and returns the commission
      float commDollars = 0.0;

      if (amountSold <= 100000)
            commDollars = amountSold * .02;
      else if (amountSold <= 400000)
            commDollars = 2000 + .05 * (amountSold - 100000);
      else commDollars = 17000 + .1 * (amountSold - 400000);
      //end ifs
      return commDollars;
}      //end of calcCommission function

int getAndValidateSales(int &sales)
      int salesData = 0;

      if (sales > 0)
            salesData = 1;
      else salesData = 2;
      return salesData;
}      //end getAndValidateSales

You have not called getAndValidateSales () fuction
call that function after accepting the value of sales and take the return value in salesData

something like

salesData = getAndValidateSales ( sales ) ;
if ( salesData == 1 ) .............

Also, in your if condition, u are assigning 1 to salesData instead of checking it
In C/C++, for checking equality, u should use == as shown above
