Thread: For Loops (Making Stars)

I'm working on this program for school and I need the output to look like this

This is the code I have so far. I can't seem to make it work and honestly I can't understand the logic of the for statement for this. Could someone please walk me through the for statement?

Code:

#include <iostream>
using namespace std;


int main ()
{
	int row_Col = 0;
	int i = 0;
	int m = 0;
	int n = 0;
	bool start = 0;
	char answer;

	const char star = '*';

	cout << "Drawing hallow boxes program " << endl;
	cout << "\n\n";
	
	cout << "Do you want to start (y/n): " << endl;
	cin >> answer;
	cout << "\n\n";

	
	if (answer == 'y' || answer == 'Y')
	{
		start = true;
	}
	else if (answer == 'n' || answer == 'N')
	{	
		start = false;
	}
	else 
	{
		cout << "You entered an invalid character" <<endl;
	}

	while (start == true)	
	{	

		cout << "How many rows/columns would you like to work with? " << endl;
		cin >> row_Col;
		cout << "\n\n";

		while (row_Col < 5 || row_Col > 21)
		{
			cout << "Out of range!  Reenter: " << endl;
			cout << "\n\n";
			cin >> row_Col;
		}

		for (i = 1; i <= row_Col; i++)
		{
			for(m = 0; m < row_Col; m=m++)
			{
				cout << star;
			}

		}
			

		cout << "Do you want to start (y/n): " << endl;
		cin >> answer;
		cout << "\n\n";
		
		if (answer == 'n' || answer == 'N')
		{
			start = false;
		}
	}



	return 0;
	std::cin.get();

}// End of program!
