C++ Program to Print Pyramid Numbers Pattern

Write a C++ program to print pyramid numbers pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int rows;

	cout << "Enter Pyramid Number Pattern Rows = ";
	cin >> rows;

	cout << "Printing Pyramid Number Pattern\n";

	for (int i = 1; i <= rows; i++)
	{
		for (int j = rows; j > i; j--)
		{
			cout << " ";
		}
		for (int k = 1; k <= i; k++)
		{
			cout << i << " ";
		}
		cout << "\n";
	}
}
C++ Program to Print Pyramid Numbers Pattern

This program helps to print pyramid numbers patterns using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int rows, i, j, k;

	cout << "Enter Rows = ";
	cin >> rows;

	cout << "Printing\n";
	i = 1;

	while (i <= rows)
	{
		j = rows;
		while (j > i)
		{
			cout << " ";
			j--;
		}

		k = 1;
		while (k <= i)
		{
			cout << i << " ";
			k++;
		}

		cout << "\n";
		i++;
	}
}
Enter Rows = 8
Printing
       1 
      2 2 
     3 3 3 
    4 4 4 4 
   5 5 5 5 5 
  6 6 6 6 6 6 
 7 7 7 7 7 7 7 
8 8 8 8 8 8 8 8 

This example displays the pyramid pattern of numbers using the do while loop.

#include<iostream>
using namespace std;

int main()
{
	int rows, i, j, k;

	cout << "Enter Rows = ";
	cin >> rows;

	i = 1;

	do
	{
		j = rows;
		do
		{
			cout << " ";

		} while (j-- > i);

		k = 1;
		do
		{
			cout << i << " ";

		} while (++k <= i);

		cout << "\n";

	} while (++i <= rows);
}
Enter Rows = 9

         1 
        2 2 
       3 3 3 
      4 4 4 4 
     5 5 5 5 5 
    6 6 6 6 6 6 
   7 7 7 7 7 7 7 
  8 8 8 8 8 8 8 8 
 9 9 9 9 9 9 9 9 9
