Cpp program to Hollow Pyramid Pattern

Cpp program to Hollow Pyramid Pattern

In this tutorial, we will  discuss the concept of Cpp program to Hollow Pyramid Pattern

In this topic, we will learn how to create hollow pyramid star pattern in C++ programming language using nested for loop

Hollow Pyramid pattern

Program 1

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int rows;
    cout << "Enter the rows for hollow pyramid" << endl;
    cin>>rows;
    for(int i=1; i<=rows; i++){//do print each rows
        for(int j=i; j<=rows; j++){ //print space for pyramid
        cout<<" ";
    }
    for(int k=1; k<2*i; k++){
            if(i==rows || (k==1 || k==2*i-1)){
                cout<<"*";
            }
            else{
                cout<<" ";
            }


    }
    cout<<"\n"; //move to next line
    }
    getch();
    return 0;
}

When the above code is executed, it produces the following results:

            }


    }

    }
    getch();
    return 0;
}
