C++ Inverted Pyramid Program

This program helps you to learn the fundamental structure and syntax of C++ programming.

Try This Code
#include <iostream>
using namespace std;

int main() {
    int rows;
    
    cout << "Enter number of rows: ";
    cin >> rows;
    
    for (int i = rows; i >= 1; i--) {
        // Print spaces
        for (int j = 1; j <= rows - i; j++) {
            cout << " ";
        }
        // Print stars
        for (int j = 1; j <= 2 * i - 1; j++) {
            cout << "*";
        }
        cout << endl;
    }
    
    return 0;
}
Output
Enter number of rows: 5

Understanding Inverted Pyramid

An inverted pyramid is the reverse of a full pyramid. We iterate from rows down to 1. For row i, we print (rows - i) spaces, then (2*i - 1) stars. The number of stars decreases as we go down.

Note: To write and run C++ programs, you need to set up the local environment on your computer. Refer to the complete article Setting up C++ Development Environment. If you do not want to set up the local environment on your computer, you can also use online IDE to write and run your C++ programs.
