Chapter 3, Problem 1E

Write a fragment of code that will test whether an integer variable score contains a valid test score. Valid test scores are in the range 0 to 100.

Program Plan Intro

Program plan:

• • Include necessary header files.
• • Define the class “Fragments”.
• • Define the “main()” function.
  • ○ Declare and initialize the necessary variables.
  • ○ The “if” statement check the condition.
    • ■ True, print the valid statement.
  • ○ Otherwise, print the invalid statement.

Program Description Answer

Program to display the valid test score.

Explanation of Solution

Program:

//Import necessary header files

import java.util.*;

//Define the class

class Fragments

{

    //Define the main() method

    public static void main(String[] args)

    {

        //Initialize the variable

        int score = 10;

        //Check the condition

        if( score >= 0 && score <= 100 )

        {

            //True, print the statement

            System.out.println("The score " + score + " is valid.");

        }

        //Otherwise

        else

        {

            //Print the statement

            System.out.println("The score " + score + " is not valid.");

        }

    }

}

Sample Output

Output:

The score 10 is valid.
