How to print Hollow Pyramid Pattern in C++ - Step by Step Examples

How to print Hollow Pyramid Pattern in C++ ?

Answer

To print a hollow pyramid pattern in C++, you can use loops. The outer loop controls the rows, and the inner loops manage the spaces and stars to create the hollow effect.

✐ Examples

1 Hollow Pyramid Pattern (Height: 5) in C++

In this example,

Set the number of rows for the pyramid.
Use nested loops: one for rows, one for spaces, and one for stars.
In the inner loops, print spaces for the spaces between stars and print stars for the pyramid edges.
Adjust conditions to print stars only at the pyramid edges and spaces elsewhere to create the hollow effect.
Print each row to create the hollow pyramid pattern.

C++ Program

#include <iostream>
using namespace std;

void printHollowPyramid(int rows) {
    for (int i = 1; i <= rows; i++) {
        for (int j = i; j < rows; j++) {
            cout << "  ";
        }
        for (int k = 1; k < (2 * i); k++) {
            if (k == 1 || k == (2 * i - 1) || i == rows) {
                cout << "* ";
            } else {
                cout << "  ";
            }
        }
        cout << endl;
    }
}

int main() {
    printHollowPyramid(5);
    return 0;
}

Output

        * 
      *   * 
    *       * 
  *           * 
* * * * * * * * *
