C++ Hollow mirrored inverted right triangle star pattern

In this article, we will discuss the C++ Hollow mirrored inverted right triangle star pattern

We can display many types of number, star, Alphabet, Binary patterns using for.while and do-while loop in C++ language

In this post, we are going to learn how to print Hollow inverted mirrored right Triangle Star Pattern using for, while and do-while loop in C++ language,

Program to print triangle star pattern

Code to display Hollow Inverted mirrored right triangle star using for loop

This program allows the user to enter the number of rows with any symbols then the program displays the Hollow Inverted mirrored right triangle star pattern using for loop in C++ language

Program 1

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

int main()
{
     int i,j,rows;
    char ch;
    cout<<"Enter the number of rows\n";
    cin>>rows;
     cout<<"Enter the Symbol for pattern\n";
     cin>>ch;

    cout<<"\n";
    for(i=1; i<=rows; i++){//outer for loop
   for(j=1; j<i; j++){//inner for loop
   cout<<" ";
   }
   for(j=i; j<=rows; j++){//inner for loop
   if(j==i || j==rows || i==1){
   cout<<ch;//print character
   }
   else{
     cout<<" ";//print space
   }
   }
   cout<<"\n";//move to next line
}
getch();
    return 0;
}

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