Program to display Rhombus star patterns in C++ language
In this article, we will discuss the concept of Program to display Rhombus star patterns using while loop in C++ language.
In this post, we are going to learn how to use a while loop for write a program to print rhombus and hollow rhombus pattern .
Print Rhombus star patterns Using while loop
Code to print Rhombus pattern using while loop

Program 1
This program allows the user to enter the number of rows and symbols then it will display the rhombus pattern using while loop in C++ programming language
#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 for loop
j=1;
while(j<=rows-i){//inner for loop
cout<<" ";//print space
j++;
}
j=1;
while(j<=rows){//inner for loop
cout<<ch;//print character after space
j++;
}
cout<<"\n";//move to next line
i++;
}
getch();
return 0;
}
When the above code is executed, it produces the following result
Code to print Hollow Rhombus pattern using while loop
Program 2
This program allows the user to enter the number of rows and symbols then it will display the Hollow rhombus pattern using while loop in C++ programming language
#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 for loop
j=1;
while(j<=rows-i){//inner for loop
cout<<" ";//print space
j++;
}
j=1;
while(j<=rows){//inner for loop
if(i==1 || i==rows || j==1 || j==rows){
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
