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

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 inverted right Triangle Star Pattern using for, while and do-while loop in C++ language,

Program to print inverted right triangle star pattern

Code to display Hollow Inverted right triangle star using for loop

This program allows the user to enter the number of rows with symbols then the program displays the Inverted 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
   if(i==1 || j==i || j==rows){
   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
