C++ Program to Print Consecutive Column Numbers in Right Triangle

Write a C++ program to print consecutive column numbers in the right triangle pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, k, rows;
     
    cout << "Enter Right Triangle of Consecutive Col Nums = ";
    cin >> rows;

    cout << "Consecutive Column Numbers in a Right Triangle Pattern\n"; 
    k = 1;
    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= i; j++)
		{
            cout << k++ << " ";
        }
        cout << "\n";
    }		
 	return 0;
}

This C++ example prints the right angled triangle pattern of consecutive column numbers using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, k, rows;
     
    cout << "Enter Right Triangle of Consecutive Col Nums = ";
    cin >> rows;

    cout << "Consecutive Column Numbers in a Right Triangle Pattern\n"; 
    k = 1;
    i = 1;
    while(i <= rows)
    {
        j = 1;
    	while( j <= i)
		{
            cout << k++ << " ";
            j++;
        }
        cout << "\n";
        i++;
    }		
 	return 0;
}

Enter Right Triangle of Consecutive Col Nums = 10
