Question :

Q.Write a program in any of your favorite programming language.

This similar to product rating.

The input is X ( X is a decimal number ,which is belongs to {0, 0.5, 1, 1.5, 2, .., MAX})

The output should be a string that consists of "FS","HS","FE" (represents full star, half star, full empty)

X Can be any decimal number ( multiples of 0.5 )

MAX Can be any number.

Examples:

if user gives input as 1.5, 5 , then output should be "FS,HS,FE,FE,FE" (which means fullstar,half star, full empty, full empty,full empty)

if user gives input as 0 , 5 , then output should be "FE,FE,FE,FE,FE" (which means five full emptys)

if user gives input as 3 , 5 then output should be "FS,FS,FS,FE,FE" (which denotes 3 fullstars , 2emptys )

if user gives input as 5 , 5 then output should be "FS,FS,FS,FS,FS" (which denotes 5 fullstars )

if user gives input as X=1.5, MAX=8 , then output should be "FS,HS,FE,FE,FE,FE,FE,FE"

(which means fullstar,half star, full empty, full empty,full empty, full empty, full empty,full empty)

if user gives input as 7 , 10 , then output should be "FS,FS,FS,FS,FS,FS,FS,FE,FE,FE"

if user gives input as 8.5 , 12 then output should be "FS,FS,FS,FS,FS,FS,FS,FS,HS,FE,FE,FE"

if user gives input as 11.5 , 15 then output should be "FS,FS,FS,FS,FS,FS,FS,FS,FS,FS,FS,HS,FE,FE,FE,FE"

After reading the input from the console the program then splits it into two parts using the comma as separator and stores the two elements in an array. If the length of the array is not two then there's something wrong with the input and the program terminates. The program then attempts to parse the first element (items[0]) to a double and assign it to the variable 'x'. If it's not a number is less than zero or if it's not a multiple of 0.5 the input is rejected and the program terminates. Next the program attempts to parse the second element (items[1]) to an int and assign it to the variable 'max'. If it's not a number is less than one or is less than the actual rating (x) the input is rejected and the program terminates. The program then creates a string array with 'max' elements. It then finds the integer part of 'x' and assigns it to the variable 'whole'. Next the first 'whole' elements of the array are assigned the value FS and the remaining elements are assigned the value FE. If 'x' is not a whole number (i.e. it's greater than 'whole') the (whole + 1)th element is assigned the value HS overwriting the previous value of FE. Finally a string is created consisting of the elements of the array separated by commas and this string is output to the console. Console.ReadKey() makes sure the console stays open (until the user pressed a key) so the output can be read - only necessary in some circumstances.

Here's a C# version: using System; class Program { static void Main() { Console.WriteLine(Enter the product rating in the form X MAX); string input = Console.ReadLine(); string[] items = input.Split(''); if (items.Length != 2) { Console.WriteLine(Invalid input); return; } double x; bool isValid = double.TryParse(items[0] out x); if(!isValid || x { Console.WriteLine(Sorry not a valid rating); return; } int max; isValid = int.TryParse(items[1] out max); if(!isValid || max max) { Console.WriteLine(Sorry not a valid MAX); return; } string[] ratings = new string[max]; int whole = (int)x; for(int i = 0; i for(int i = whole; i if (x > whole) ratings[whole] = HS; string output = String.Join( ratings); Console.WriteLine(output); Console.ReadKey(); } }

Java code: import java.util.Scanner; public class ProductRating { public static void main(String[] args) { System.out.println(bism); String s; float actualRating = 0.0f; int maxRating = 0; Scanner in = new Scanner(System.in); System.out.println(Enter the actual product rating); s = in.nextLine(); actualRating = Float.valueOf(s).floatValue(); System.out.println(Enter the maximum product rating); s = in.nextLine(); maxRating = Integer.valueOf(s).intValue(); System.out.println(  + actualRating +  out of  + maxRating); for (int i = 1; i if (i System.out.println(FS); } if (i > Math.ceil(actualRating)) { System.out.println(FE); } if (i == actualRating) { System.out.println(FS); } else if (i == Math.ceil(actualRating)) { System.out.println(HS); } } } }
