using namespace std;

int main()
{
	int i, j, rows;
     
    cout << "Enter Simple Number Pattern Rows = ";
    cin >> rows;

    cout << "Simple Number Pattern\n"; 

    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= i; j++)
		{
            cout << j << " ";
        }
        cout << "\n";
    }		
 	return 0;
}

This C++ example displays the numbers in the right angled triangle using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i = 1, j, rows;
     
    cout << "Enter Rows = ";
    cin >> rows;


    while(i <= rows)
    {
        j = 1; 
    	while(j <= i)
		{
            cout << j << " ";
            j++;
        }
        cout << "\n";
        i++;
    }		
 	return 0;
}
Enter Rows = 14
