C++ program to Hollow Mirrored Right Triangle Star Pattern

In this article, we will discuss the C++ program to Hollow Mirrored Right Triangle Star Pattern in C++ language

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 Mirrored Right Triangle Star Pattern Program using for, while and do-while loop in C++ language,

Program to print mirrored right triangle star pattern

Code to display Hollow Mirrored right triangle star using for loop

This program allows the user to enter the number of rows and with symbols then the program displays the Hollow 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=i; j<rows; j++){//inner for loop
   //print rows number of star

       cout<<" ";

}
for(j=1; j<=i; j++){
  if(i==rows || j==1 || j==i){
   cout<<ch;
  }
  else{
    cout<<" ";
  }
}
 cout<<"\n";//move to next line
}
getch();
    //printf("Hello world!\n");
    return 0;
}

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