C++ code:Print Mirrored Rhombus star pattern using do-while loop

C++ code:Print Mirrored Rhombus star pattern using do-while loop

In this article, we will discuss the concept of C++ code:Print Mirrored Rhombus star pattern using do-while loop

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

 

Display Mirrored Rhombus  star patterns Using do-while loop

Code to print mirrored rhombus star pattern

Program 1

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

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

int main() {
    int i,j,rows;
    //Variable declaration for integer
    char ch;
    //Variable declaration for character
    cout<<"Enter the number of rows\n";
    //Ask input from the user for Number of rows
cin>>rows;
//Reading the number of rows value
cout<<"Enter the Symbol for pattern\n";
//Ask input from the user for Symbol
cin>>ch;
//Reading the character value
cout<<"\n";
//move to next line
i=1;
do{//outer while loop
        j=1;
  do{//inner while loop
   cout<<" ";//print space
j++;
   } while(j<=i);
   j=1;
   do{//inner while loop
   cout<<ch;//print symbol after space
    j++;
}while(j<=rows);
 cout<<"\n";//move to next line
  i++;
}while(i<=rows);
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 , and any symbols then it will display  the Hollow mirrored rhombus    star pattern using do-while loop in C++ programming language

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

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