Repeating Action?

I'm supposed to print off stars. I prompt the user for a number (we'll call it n), and then print out n lines of stars. The first line will have one star and then it adds one each line.

eg.
Enter the number of lines -> 5

I have this:

Code:

---

#include <iostream>
        using namespace std;

        int main() {
            int n;
            cout << "Enter the number of lines." << endl;
            while (cin >> n) {
                //--- Loop counting i up from 1 to n.
                int i = 1;          // Initialize counter.
                while (i <= n) {    // Test counter.
                    cout << "*";
                    i++;            // Increment counter.
                }
                cout << endl;
            }
            return 0;
        }

That gives me the entered number of stars but I don't know how to get the lines of stars up to that point.

eg. If I run it now:
Enter number of lines -> 5

The problem is here

while (cin >> n)

Put the cin outside the while and make it similar to the inner loop.

Use nested loops: An outer loop to loop over the lines you want to write (user a loop variable row), an inner loop to write as many stars as suitable for this line (the current value of row). After the inner loop, write a line feed character (\n).
