int main ()
{
	int n, i, j, l;
	
	// Read in a postive number with data validation
	do
	{
		cout << "Enter an interger less 10: ";
		cin >> n;
	}while (n < 0 || n >= 10);
	
	
       do
       {
	  for (l = 1; l <= n; l++)
		{   for (i = 1; i <= l; i++)

				cout << "*" << " ";
		 	 	cout <<endl;

			int i = 1;
			
			while (i <= l)
			{
				for (j = 1; j <= i; ++j)
					cout << "&" << " ";
		 	 		cout <<endl;
					i++;
			}



cause the upper portion i need to use for loop. sorry just now my qns was unclear.
the ++j is to make it display as square.
