C++ Program to Print Same Numbers on all Sides of a Square

Write a C++ program to print the same numbers on all sides of a square pattern using for loop.

#include<iostream>
using namespace std;

int main()
{
	int i, j, k, min, rows;
     
    cout << "Enter Sqaure Number Rows = ";
    cin >> rows;

    cout << "Print Same Number in All Sides of a Square Pattern\n"; 

    for(i = 1; i <= rows; i++)
    {
    	for(j = 1; j <= rows; j++)
		{
            min = i < j? i: j;
            cout << rows - min + 1 << " ";
        }
        for(k = rows - 1; k >= 1; k--)
        {
            min = i < k? i:k;
            cout << rows - min + 1 << " ";
        }
        cout << "\n";
    }	

    for(i = rows - 1; i >= 1; i--)
    {
    	for(j = 1; j <= rows; j++)
		{
            min = i < j? i:j;
            cout << rows - min + 1 << " ";
        }
        for(k = rows - 1; k >= 1; k--)
        {
            min = i < k? i:k;
            cout << rows - min + 1 << " ";
        }
        cout << "\n";
    }
	
 	return 0;
}
C++ Program to Print Same Numbers on all Sides of a Square

This C++ example prints the square pattern where all sides have the same numbers using a while loop.

#include<iostream>
using namespace std;

int main()
{
	int i = 1, j, k, min, rows;
     
    cout << "Enter Sqaure Number Rows = ";
    cin >> rows;

    cout << "Print Same Number in All Sides of a Square Pattern\n"; 

    while( i <= rows)
    {
        j = 1;
    	while( j <= rows)
		{
            min = i < j? i: j;
            cout << rows - min + 1 << " ";
            j++;
        }
        k = rows - 1;
        while( k >= 1)
        {
            min = i < k? i:k;
            cout << rows - min + 1 << " ";
            k--;
        }
        cout << "\n";
        i++;
    }	

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