C++ Program to Print Square Number Pattern

Write a C++ Program to Print Square Number Pattern with an example. In this C++ example, we used nested for loop to print 1’s in a square pattern.

#include<iostream>
using namespace std;

int main()
{
	int i, j, side;
     
    cout << "\nPlease Enter Any Side of a Square = ";
    cin >> side;
     
    for(i = 0; i < side; i++)
    {
    	for(j = 0; j < side; j++)
		{
           	cout << "1";
        }
        cout << "\n";
    }
		
 	return 0;
}

C++ Program to Print Square Pattern of 0’s

#include<iostream>
using namespace std;

int main()
{
	int i, j, side;
     
    cout << "\nPlease Enter Any Side of a Square = ";
    cin >> side;
     
    for(i = 0; i < side; i++)
    {
    	for(j = 0; j < side; j++)
		{
           	cout << "0";
        }
        cout << "\n";
    }
		
 	return 0;
}

Output

Please Enter Any Side of a Square = 10
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000
0000000000

C++ Program to Print Square Number Pattern using a While Loop

#include<iostream>
using namespace std;

int main()
{
	int i, j, side;
     
    cout << "\nPlease Enter Any Side of a Square = ";
    cin >> side;
    
    i = 0;  
    while(i < side)
    {
    	j = 0;
    	while( j < side)
		{
           	cout << "1";
           	j++;
        }
        cout << "\n";
        i++;
    }
		
 	return 0;
}

Output

Please Enter Any Side of a Square = 7
1111111
1111111
1111111
1111111
1111111
1111111
1111111

This C++ Square Number Pattern example allows the user to enter any number, then print that number in the square.

#include<iostream>
using namespace std;

int main()
{
	int number, i, j, side;
     
    cout << "\nPlease Enter Any Side of a Square = ";
    cin >> side;
    
	cout << "\nPlease Enter Any Integer Value to Print as a Square = ";
    cin >> number;
	 
    for(i = 0; i < side; i++)
    {
    	for(j = 0; j < side; j++)
		{
           	cout << number;
        }
        cout << "\n";
    }
		
 	return 0;
}

Output

Please Enter Any Side of a Square = 8

Please Enter Any Integer Value to Print as a Square = 9
