Question

1. Write a program that prints a set of sqaures based on the widths stored in an array. Below are the specifications:  Ask the user for the number of sqaures to be printed  Create an array (based on the number of sqaures) to hold the widths  Ask the user for widths and store in the array  Print the sqaures (using any character (e.g. asterisk)) based on the widths stored in the array. (Java language)

Answer 1

import java.util.Scanner;

class Squares
{
   public static void main (String[] args)
   {
       Scanner input = new Scanner(System.in);
       System.out.println("Enter the number of squares to be printed : ");
       int n = input.nextInt();
      
       int[] arr = new int[n];
      
       System.out.println("Enter "+ n + " widths : ");
       for(int i=0;i<n;i++)
       {
           arr[i] = input.nextInt();
       }
      
       for(int i=0;i<n;i++)
       {
           for(int j=0;j<arr[i];j++)
           {
               for(int k=0;k<arr[i];k++)
               {
                   System.out.print("*");
               }
               System.out.println();
           }
           System.out.println();
       }
      
   }
}

Output:

Enter the number of squares to be printed : 5
Enter 5 widths : 6 4 3 2 8
