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

Are you a job seeker and trying to find simple java programs for Interview? This would be the right choice for you, just tap on the link and start preparing the java programs covered to crack the interview.

Approach:

  • Enter size of the pattern and store it in an integer variable size.
  • Take one outer for loop to iterate the rows.
  • Take one inner for loops, to iterate the columns.
  • After each iteration print a newline.

JAVA Code:

import java.util.Scanner;
class pattern
{
public static void main(String[] args)
{
    int size, r, c;
    //Taking size as input from user
    System.out.print("Size : ");
    Scanner scan = new Scanner(System.in);
    size = scan.nextInt();

    //Taking middle row of the pattern
    int mid = size / 2 + 1;
    //Outer Loop
    for (r = 1; r <= size; r++)
    {
        //Inner loop
        for (c = 1; c <= size; c++)
        {
            if (c == size / 2 + 1 || c == mid || c == size - mid + 1)
                System.out.print("*");
            else
                System.out.print(" ");
        }
        //Prints a newline
        System.out.println();
        //Incrementing the mid value
        mid++;
    }
}
}


Output

Size : 5

C Code:

#include <stdio.h>

int main()
{
    int size, r, c;
    //Taking size as input from user
    printf("Size : ");
    scanf("%d", &size);

    //Taking middle of the pattern
    int mid = size / 2 + 1;
    //Outer Loop
    for (r = 1; r <= size; r++)
    {
        //Inner loop
        for (c = 1; c <= size; c++)
        {
            if (c == size / 2 + 1 || c == mid || c == size - mid + 1)
                printf("*");
            else
                printf(" ");
        }
        //Prints a newline
        printf("\n");
        //incrementing the mid value
        mid++;
    }
    return 0;
}

Output:

Size : 5

C++ Code:

#include <iostream>
using namespace std;
int main(int argc, char const *argv[])
{
    int size, r, c;
    //Taking size as input from user
    cout << "Size : ";
    cin >> size;

    //Taking middle of the pattern
    int mid = size / 2 + 1;
    //Outer Loop
    for (r = 1; r <= size; r++)
    {
        //Inner loop
        for (c = 1; c <= size; c++)
        {
            if (c == size / 2 + 1 || c == mid || c == size - mid + 1)
                cout << "*";
            else
                cout << " ";
        }
        //Prints a newline
        cout << endl;
        //Incrementing the mid value
        mid++;
    }
    return 0;
}


Output:

Size : 5
