In this article, we are going to learn about how to print half Pyramid and full Pyramid patterns in C++ language. First, we are going to print the half Pyramid and then in the next program, we will print the full Pyramid.

  • How to print half Pyramid using * in C++ language.
  • How to print full Pyramid using * in C++ language.

How to print half Pyramid using * in C++ language.

In this example, we are going to print the half * pyramid using C++ language. We will make use of the for loops.

Desired Output for Size 5:

C++ Program to print half Pyramid pattern

#include <iostream>
using namespace std;
int main()
{
  int num, row, col;

  cout<<"Please enter the number of rows: ";
  cin>>num;

  for(row = 1; row <= num; row++)
  {
    for(int s=1;s<=num-row;s++) 
        cout<<" ";
    for(col = 1;col <= row; col++) 
        cout<<"*";

    cout<<"\n";
  }

  return 0;
}

Output

Please enter the number of rows: 5
