C++ code to Hollow Rhombus star pattern|C++ patterns

In this article, we will discuss the C++ code to Hollow Rhombus 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 Rhombus Star Pattern using for, while and do-while loop in c++ language.

Note – Here,To create a Mirrored Rhombus pattern, you can use either star or any symbol as you wish

Code to display Rhombus pattern using for loop

This program allows the user to enter the number of rows and any character then the program displays the Hollow Rhombus 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<=rows-i; j++){//inner for loop
   cout<<" ";//print space
   }
   for(j=1; j<=rows; j++){//inner for loop
   if(i==1 || i==rows || j==1 || j==rows){
   cout<<ch;//print symbol after space
   }
   else{
       cout<<" ";//print space
   }
}
 cout<<"\n";//move to next line
}
getch();
    return 0;
}

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

Code to display Rhombus pattern using while loop

This program allows the user to enter the number of rows and any character then the program displays the Hollow Rhombus star pattern using while loop in C++ language

Program 2

#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";
    i=1;
    while(i<=rows){//outer while loop
            j=1;
   while(j<=rows-i){//inner while loop
   cout<<" ";//print space
   j++;
   }
   j=1;
   while(j<=rows){//inner while loop
   if(i==1 || i==rows || j==1 || j==rows){
   cout<<ch;//print character 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

Hollow Rhombus star pattern

Code to display Rhombus pattern using do-while loop

This program allows the user to enter the number of rows and any character then the program displays the Hollow Rhombus star pattern using do-while loop in C++ language

Program 3

#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";
    i=1;
    do{//outer do while loop
            j=0;
   do{//inner do while loop
   cout<<" ";//print space
   j++;
   }while(j<=rows-i);
   j=1;
   do{//inner do while loop
   if(i==1 || i==rows || j==1 || j==rows){
   cout<<ch;//print character 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
