Need help for C++ programming

Hi,
I am back again with another problem. Hope someone can help. I can get the program to run, but I cannot figure out how to end the program when sales < than 0 for each section.

The problem is this:

Create a program that displays the sum of the sales amounts made in each of four regtions (North, East, South, and West) during a 3 month period. The program also should display the total sales made during the three months. The C++ code should allow the user to enter 4 sets (one set for each region) of 3 sales amounts (one sales amount for each month). The program should display each region's total sales for the 3-month period, and the company's total sales for the 3-month period.
Use the following four sets of data to test the program:
2000, 4000, 3000
2000, 5000, 5000
3000, 2000, 1000
4000, 1000, 6000

Here is my program so far:

Code:

 
#include <iostream>
using std::cout;
using std::cin;
using std::endl;
 
int main()
{

 //declare variables
 int northRegionSales = 0;
 int totalNorthSales = 0;
 int northRegion = 1;
 int eastRegionSales = 0;
 int totalEastSales = 0;
 int eastRegion = 1;
 int southRegionSales = 0;
 int totalSouthSales = 0;
 int southRegion = 1;
 int westRegionSales = 0;
 int totalWestSales = 0;
 int westRegion = 1;
 int totalSales = 0;
 
 //enter sales amounts for North region
 cout << "Sales amount for North region (negative number to stop): $ ";
 cin >> northRegionSales;
 do
 {
  northRegion += 1;
  totalNorthSales = totalNorthSales + northRegionSales;
  cout << "Next sales amount for North region (negative number to stop): $ ";
  cin >> northRegionSales;
 } while (northRegion <= 2); 
 cout << endl;
 totalNorthSales = totalNorthSales + northRegionSales;
 
  //enter sales amounts for East region
  cout << "Sales amount for East region (negative number to stop): $ ";
  cin >> eastRegionSales;
   do
   {
    eastRegion += 1;
    totalEastSales = totalEastSales + eastRegionSales;
    cout << "Next sales amount for East region (negative number to stop): $ ";
    cin >> eastRegionSales;
   } while (eastRegion <= 2);
   cout << endl;
   totalEastSales = totalEastSales + eastRegionSales;

  //enter sales amounts for South region
  cout << "Sales amount for South region (negative number to stop): $ ";
  cin >> southRegionSales;
   do
   {
    southRegion += 1;
    totalSouthSales = totalSouthSales + southRegionSales;
    cout << "Next sales amount for South region (negative number to stop): $ ";
    cin >> southRegionSales;
   } while (southRegion <= 2);
  cout << endl;
  totalSouthSales = totalSouthSales + southRegionSales;
 
  //enter sales amounts for West region
  cout << "Sales amount for West region (negative number to stop): $ ";
  cin >> westRegionSales;
   do
   {
    westRegion += 1;
    totalWestSales = totalWestSales + westRegionSales;
    cout << "Next sales amount for South region (negative number to stop): $ ";
    cin >> westRegionSales;
   } while (westRegion <= 2);
  cout << endl;
  totalWestSales = totalWestSales + westRegionSales;
 // end do while
 
  //display total sales for each region
  cout << "Total sales for North region: $ " << totalNorthSales << endl;
  cout << "Total sales for East region: $ " << totalEastSales << endl;
  cout << "Total sales for South region: $ " << totalSouthSales << endl;
  cout << "Total sales for West region: $ " << totalWestSales << endl;
  totalSales = totalNorthSales + totalEastSales + totalSouthSales + totalWestSales;
  cout << "Total sales: $ " << totalSales << endl;
  return 0;
}   //end of main function
 

Thank u for your help! :cryin:

 

Can anyone give me an idea of what to try? PLEASE, PLEASE, PLEASE! :freak:

Thank you for your time,
Lori

 

if i understand correctly what you want try this

Code:

 //enter sales amounts for North region
 cout << "Sales amount for North region (negative number to stop): $ ";
 cin >> northRegionSales;
 [COLOR=Red]while (northRegion <3 && northRegionSales>=0)[/COLOR]
 {
  northRegion++;
  totalNorthSales = totalNorthSales + northRegionSales;
  cout << "Next sales amount for North region (negative number to stop): $ ";
  cin >> northRegionSales;
 [COLOR=Red]}[/COLOR]
 cout << endl;
[COLOR=Red] if (northRegionSales>=0) [/COLOR]totalNorthSales = totalNorthSales + northRegionSales;
 
  //enter sales amounts for East region

do the same changes for the rest regions

 

Where were u yesterday when I needed you, lol. I do think this will work. I was using the wrong loop command I guess. Plus, I did not know that you could use two different variable in one condition. I will try this and let you know how it goes. Thank you so much.

OK, this works great, but shouldn't the program go to the very end as soon as a negative number is entered. Is this even possible?

 

if you want to terminate your program immediately you can do this:
if (northRegionSales<0) exit(1);

put it under all
cin<<nortRegionSales;

 

How do I change the post title? I don't see a way to edit it.

 

What does the "exit (1) in the following mean? We have not covered that in computer class yet.

if you want to terminate your program immediately you can do this:
if (northRegionSales<0) exit(1);

put it under all
cin<<nortRegionSales;

 

http://www.cplusplus.com/reference/clibrary/cstdlib/exit/

when you finish main() you use return 0; ---->(exit(0) finished without errors)
exit(1) --->reurns 1 which means the program terminated with error.
