# C++ Reverse Half Pyramid Pattern using Asterix (*)

Hello Everyone!

In this tutorial, we will learn how to print a Reverse Half Pyramid Structure using *, 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 Reverse Half Pyramid using * ===== \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 Reverse Pyramid pattern containing " << rows << " rows is:\n\n";

//outer loop is used to move to a particular row
for (i = 1; i <= rows; i++)
{
//to display that the outer loop maintains the row number
cout << "Row # " << i << " contains " << (rows - i + 1) << " stars :  ";

//inner loop is used to decide the number of * in a particular row
for (j = rows; j >= i; j--)
{
cout << "* ";
}

cout << endl;
}

cout << "\n\n";

return 0;
}``````

Output:

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 : )
