Display integrated pyramid star pattern in C++ using while loop

Display integrated pyramid star pattern in C++ using while loop

In this tutorial, we will discuss a concept of  Display integrated pyramid star pattern in C++ using while loop

In C++ language, we can use for loop ,while loop and  do-while loop to display different number (binary, decimal), alphabets or star pattern programs.

In this article, we are going to learn  how to Display double pyramid star pattern  using while loop in C++ language

integrated pyramid Star pattern 1

Program 1

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

int main()
{
    int i,j,rows;
    cout<<"Enter the number of rows for pattern: ";
    cin>>rows;   //get input from the user for number of rows
    i=1;
while(i<=rows){  
    j=i;
    while(j<=rows){    //Print upper part of pattern
        cout<<"*";
        j++;
    }
    i++;
    cout<<"\n";
}

i=rows-1;
while(i>=1){
    j=i;
    while(j<=rows){
        cout<<"*";
        j++;
    }
    i--;
    cout<<"\n";
}
getch();
    return 0;
}

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