C++ Half Pyramid Pattern using Numbers Program

Hello Everyone!

In this tutorial, we will learn how to print a Half Pyramid Structure using Numbers, in the C++ programming language.

All such patterns using * or alphabets or numbers are achieved by making use of the nested loop structures by knowing how to iterate and till where to iterate.

We believe that all the patterns covered in this section will help you understand this concept and visualize it better while forming your own patterns, as such questions are very frequently asked in various interviews with a slight modification.

Code:

#include <iostream>
using namespace std;

int main()
{
    cout << "\n\nWelcome to Studytonight :-)\n\n\n";
    cout << " =====  Program to print a Half Pyramid using numbers ===== \n\n";

    //i to iterate the outer loop and j for the inner loop
    int i, j, rows;

    cout << "Enter the number of rows in the pyramid: ";
    cin >> rows;
    cout << "\n\nThe required pyramid pattern containing " << rows << " rows is:\n\n";

    //outer loop is used to move to a particular row
    for (i = 1; i <= rows; i++)
    {
        // cout << "Row # " << i << "   ";
        //inner loop is used to decide the number of columns in a particular row
        for (j = 1; j <= i; j++)
        {
            cout << j << " "; //printing the column number within each row
        }

        cout << endl;
    }

    cout << "\n\n";

    return 0;
}

Output:

C++ half pyramid using numbers

We will highly recommend you to first draw such patterns line by line on a paper before getting into programming them, as it will help you understand the nested structure better.

Keep Learning : )
