C++ Program to Print Floyds Triangle

Write a C++ program to print Floyds Triangle number pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, number = 1;
     
    cout << "Enter Floyd Triangle Pattern Row = ";
    cin >> rows;

    cout << "Floyd Triangle Number Pattern\n"; 

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

This example prints Floyds Triangle pattern using a while loop.

#include<iostream>
using namespace std;

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


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

Enter Row = 12
