Print Solid Square Inside a Square Number Pattern

In the previous article, we have discussed Java Program to Print Hollow Square Inside a Square Number Pattern

In this article we are going to see how to print Solid Square Inside a square number pattern.

Output:

Enter rows : 8

11111111
2            2
3  3333  3
4  4444  4
5  5555  5
6  6666  6
7            7
88888888

Now, let’s see the actual program to print it.

The best and excellent way to learn a java programming language is by practicing Simple Java Program Examples as it includes basic to advanced levels of concepts.

Approach:

  • Enter total row and store it in an integer variable row.
  • Take first for loop to print the row value and a numbers for each row.
  • Take first inner for loop to print the column value i.e., numbers according to the condition
    if ((r == 1 || r == row) || (c == 1 || c == row) || (r >= 3 && r <= row - 2) && (c >= 3 && c <= row - 2))  else it will print spaces .
  • Then go on printing the numbersl according to loop.

Java Code to Print Solid Square Inside a Square Number Pattern

import java.util.*;
public class Main 
{    
    public static void main(String args[])   
    {   
    // taking variable for loop iteration and row .
    int row,r,c;
    //creating object 
    Scanner s = new Scanner(System.in);
    // entering the number of row
    System.out.print("Enter rows : ");
    row = s.nextInt();
    //outer for loop 
    for (r = 1; r <= row; r++)
        {
            for ( c = 1; c <= row; c++)
            {
                // condition for printing numbers
                 if ((r == 1 || r == row) || (c == 1 || c == row) || (r >= 3 && r <= row - 2) && (c >= 3 && c <= row - 2))
                     System.out.print(r);
                 else
                    System.out.print(" ");
            }
            System.out.println();
        }
  }
}
Output:

Enter rows : 8

C Code to Print Solid Square Inside a Square Number Pattern

#include <stdio.h>
int main() 
{
   int r, row, c;
   printf("Enter rows: ");
   scanf("%d", &row);
   for (r = 1; r <= row; r++)
        {
            for ( c = 1; c <= row; c++)
            {
                 if ((r == 1 || r == row) || (c == 1 || c == row) || (r >= 3 && r <= row - 2) && (c >= 3 && c <= row - 2))
                      printf("%d",r);
                 else
                    printf(" ");
            }
