Didn't I do that?
I'm just a student as well, if you know of a different way to do that dynamically please post it and explain the differences.
afg, do you need help understanding dynamic memory allocation? I'm not a master on the subject but I know the basics

I can make a chart to explain it to you just like my teacher did =3

Ok, so this is the type of solution afg was looking for, with no arrays or dynamic allocation.

#include <iostream>

using namespace std;

int main()
{
  int sale1, sale2, sale3, sale4, sale5;

  cout << "Enter today's sale for store 1: ";
  cin >> sale1;
  sale1 /= 100;

  cout << "Enter today's sale for store 2: ";
  cin >> sale2;
  sale2 /= 100;

  cout << "Enter today's sale for store 3: ";
  cin >> sale3;
  sale3 /= 100;

  cout << "Enter today's sale for store 4: ";
  cin >> sale4;
  sale4 /= 100;

  cout << "Enter today's sale for store 5: ";
  cin >> sale5;
  sale5 /= 100;

  cout << endl;
  cout << "SALES BAR CHART" << endl;
  cout << "---------------" << endl;

  cout << "Store 1: ";

  cout << "\nStore 2: ";
  for ( row = 0; row < sale2; row++)
    cout << '*';

  cout << "\nStore 3: ";
  for (int row = 0; row < sale3; row++)
    cout << '*';

  cout << "\nStore 4: ";
  for (int row = 0; row < sale4; row++)
    cout << '*';

  cout << "\nStore 5: ";
  for (int row = 0; row < sale5; row++)
    cout << '*';

//cin.get();
//cin.ignore();
  system("pause>nul");
  return 0;
}

You can either use
system("pause>nul");
alone to pause the program, or use both
cin.get();
cin.ignore();
together to achieve the same result.

thanks!
one more question! (sorry!!!)

if the user inputs like 990 in sales, and you want to round up to 1000 and show 10 * instead of 9, would you use the double instead of int? and what would the same thing apply if the user were to enter a decimal value? (must be able to show dollars and cents)
