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;
 while (northRegion <3 && northRegionSales>=0)
 {
  northRegion++;
  totalNorthSales = totalNorthSales + northRegionSales;
  cout << "Next sales amount for North region (negative number to stop): $ ";
  cin >> northRegionSales;
 }
 cout << endl;
 if (northRegionSales>=0) totalNorthSales = totalNorthSales + northRegionSales;
 
  //enter sales amounts for East region
do the same changes for the rest regions
