C++ Program to Print Mirrored Half Diamond Star Pattern

Write a C++ program to print the mirrored half diamond star pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, k, rows;
     
    cout << "Enter Mirrored Half Diamond Star Pattern Row = ";
    cin >> rows;

    cout << "Mirrored Half Diamond Star Pattern\n"; 

    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= rows - i; j++)
		{
            cout << " ";
        }
        for(k = 1; k <= i; k++)
		{
            cout << "*";
        }
        cout << "\n";
    }	

    for(i = rows - 1; i > 0; i--)
    {
    	for(j = 1; j <= rows - i; j++)
		{
            cout << " ";
        }
        for(k = 1; k <= i; k++)
		{
            cout << "*";
        }
        cout << "\n";
    }	
 	return 0;
}

This C++ example prints the mirrored half diamond pattern of a given character using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i = 1, j, k, rows;
    char ch;
     
    cout << "Enter Mirrored Half Diamond Star Pattern Row = ";
    cin >> rows;

    cout << "Enter Symbol Mirrored Half Diamond Pattern = ";
    cin >> ch;

    cout << "Mirrored Half Diamond Star Pattern\n"; 

    while(i <= rows)
    {
        j = 1;
    	while( j <= rows - i)
		{
            cout << " ";
            j++;
        }
        k = 1;
        while( k <= i)
		{
            cout << ch;
            k++;
        }
        cout << "\n";
        i++;
    }	

    i = rows - 1;
    while( i > 0)
    {
    	j = 1;
    	while( j <= rows - i)
		{
            cout << " ";
            j++;
        }
        k = 1;
        while( k <= i)
		{
            cout << ch;
            k++;
        }
        cout << "\n";
        i--;
    }	
 	return 0;
}
