Mirrored and mirrored hollow parallelogram star pattern in C++ using while

In this article, we will discuss the concept of Mirrored and mirrored hollow parallelogram star pattern in C++ using while

In this post, we are going to learn how to write a program to print mirrored parallelogram, and mirrored Hollow parallelogram patterns using While loop in C++ programming language.

Display Mirrored parallelogram star patterns Using while loop

Mirrored and mirrored hollow parallelogram star pattern in C++ using while — Mirrored parallelogram star pattern

Program 1

This program allows the user to enter the number of rows ,columns and any symbols then it will display the mirrored parallelogram star pattern using While loop in C++ programming language

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

int main() {
    int i,j,rows,columns;//declare three integer variables
    char ch;//declare a char variable
    cout<<"Enter the number of rows\n";
    //Ask input for rows
    cin>>rows; //reading the user input- rows
    cout<<"Enter the number of columns\n";
       //Ask input for columns
    cin>>columns; //reading the user input- columns
    cout<<"Enter the character for pattern\n";
    //Ask  input a char for print pattern
   cin>>ch; //reading the user input- columns
    cout<<"\n";
//Move to next line
i=1;
    while(i<=rows){//outer for loop
            j=1;
   while(j<=i){//inner for loop
   cout<<" ";//print space
   j++;
   }
   j=1;
   while(j<=columns){//inner for loop
   cout<<ch;//print symbol after space
    j++;
}
 cout<<"\n";//move to next line
  i++;
}
getch();
    return 0;
}

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

Program 2

This program allows the user to enter the number of rows ,columns and any symbols then it will display the mirrored Hollow parallelogram star pattern using While loop in C++ programming language

#include <iostream>
#include <conio.h>
using namespace std;
int main() {
    int i,j,rows,columns;
    //integer variable declaration
    char ch;
    //char variable declaration
    cout<<"Enter the number of rows\n";
    //Ask input from the user
    cin>>rows; //Reading the user input for rows
    cout<<"Enter the number of columns\n";
       //Ask input from the user for columns
    cin>>columns; //Reading the user input- columns and char
    cout<<"Enter the character for pattern\n";
       //Ask input symbol from the user
    cin>>ch;
    //reading the char input
    cout<<"\n";
i=1;
    while(i<=rows){//outer for loop
            j=1;
   while(j<=i){//inner for loop
   cout<<" ";//print space
    j++;
   }
   j=1;
   while(j<=columns){//inner for loop
   if(i==1 || i==rows || j==1 || j==columns){
   cout<<ch;//print symbol after space
   }
   else{
         cout<<" ";//print space
   }
    j++;
}
 cout<<"\n";//move to next line
 i++;
}
getch();
    return 0;
}

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