C++ Program to Print Hollow Rectangle Star Pattern

Write a C++ program to print the hollow rectangle star pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, rows, columns;
     
    cout << "Enter Hollow Rectangle Rows = ";
    cin >> rows;

    cout << "Enter Hollow Rectangle Columns = ";
    cin >> columns;

    cout << "Hollow Rectangle Star Pattern\n"; 

    for(i = 0; i < rows; i++)
    {
    	for(j = 0; j < columns; j++)
		{
            if (i == 0 || i == rows - 1 || j == 0 || j == columns - 1) 
            {
                cout << "*";
            }
           	else 
            {
                cout << " ";
            } 
        }
        cout << "\n";
    }		
 	return 0;
}
C++ Program to Print Hollow Rectangle Star Pattern

This C++ example prints the hollow rectangle pattern of a given character using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i = 0, j, rows, columns;
    char ch;
     
    cout << "Enter Hollow Rectangle Rows and Columns = ";
    cin >> rows >> columns;

    cout << "Enter Symbol for Hollow Rectangle = ";
    cin >> ch;

    cout << "Hollow Rectangle Star Pattern\n"; 

    while( i < rows)
    {
        j = 0; 
    	while(j < columns)
		{
            if (i == 0 || i == rows - 1 || j == 0 || j == columns - 1) 
            {
                cout << ch;
            }
           	else 
            {
                cout << " ";
            } 
            j++;
        }
        cout << "\n";
        i++;
    }		
 	return 0;
}
Enter Hollow Rectangle Rows and Columns = 14 25
Enter Symbol for Hollow Rectangle = #
