Please Find attached c++ code file.
Explanation:
- Ask User to enter highway number.
- Check if highway is primary or auxiliary.
- Check if highway number is even / odd.
- Find Primary high number for an auxiliary highway
Check if highway is primary or auxiliary.
Use if condition to check if the entered number is in between 0 and 99.If it's true than the highway is primary otherwise it's an auxiliary highway.
Check if highway number is even / odd.
To check if a number is even or odd we use simple modulo formula. In mathematics modulo returns the reminder of a division operation on two numbers.If modulo of a number and 2 is equal to zero than that number is an even number other wise its an odd number.
Find Primary high number for an auxiliary highway
As mentioned in the question last two digits of highway number is the number of primary high.
To Find last two digits of number apply modulo operation on highway number and 100. it will provide last two digits of number specifying our primary highway.
Answer:
Here is the PayRoll class:
// PayRoll.java
package payroll; // creates payroll package for project
public class Payroll { //class definition
private String name; //private String type member variable to store name
private String id; //private String type member variable to store id
private int hours; //private int type member variable to store work hours
private double rate; //private double type member variable to store payrate of the employee
public Payroll() { //no argument constructor of PayRoll
name = ""; //initialize name field
id = ""; //initialize id field
hours = 0; //initialize hours field
rate = 0.0; } // initialize rate field
public Payroll(String NAME, String ID, int HOURS, double RATE) { //parameterized constructor
setName(NAME); //sets name value
setId(ID); //sets id value
setHours(HOURS); //sets hours value
setRate(RATE); } //sets rate value
public void setName(String NAME) { //mutator method to set name
if(NAME.equals("")) { //if name field is empty
throw new IllegalArgumentException("An employee name should not be empty."); } //throws exception
name = NAME; }
public void setId(String ID) { //mutator method to set id
if(ID.length() != 3 || !Character.isLetter(ID.charAt(0))|| !Character.isDigit(ID.charAt(1)) || !Character.isDigit(ID.charAt(2))) { //if statement checks if the length of the id is not 3, or first character of id is not a letter, or second or third character of id is not a digit
throw new IllegalArgumentException("An employee id should have the form LNN."); } //throws exception
id = ID; }
public void setHours(int HOURS) { //mutator method to set hours
if(HOURS < 0 || HOURS > 84) { //checks if working hours are less than 0 or greater than 84
throw new IllegalArgumentException("An employee's hours should neither be negative nor greater than 84"); } //throws exception
hours = HOURS; }
public void setRate(double RATE) { //mutator method to set rate
if(RATE < 0 || RATE > 25.00) { //checks if pay rate is less than 0 or greater than 25.00
throw new IllegalArgumentException("An employee's pay rate should neither be negative nor greater than 25.00"); } //throws exception
rate = RATE; }
public String getName() { //accessor method to get value of name
return name; } //returns the current value of name
public String getId() { //accessor method to get value of id
return id; } //returns the current value of id
public int getHours() { //accessor method to get value of hours
return hours; } //returns the current value of hours
public double getRate() { //accessor method to get value of rate
return rate; } } //returns the current value of rate
Explanation:
Here is the Main() class:
import java.util.Scanner; //to accept input from user
public class Main { //Main class definition
public static void main(String[] args) {//start of main() function
Payroll pay = new Payroll(); //creates object i.e. pay of PayRoll class
Scanner sc = new Scanner(System.in); //creates Scanner class object
String name,id; //declare variables to hold name and id
int hour; //declare variable to store hour
double rate; //declare variable to store pay rate
System.out.print("Enter the employee's name: "); //prompts user to enter employee name
name = sc.nextLine(); //reads input value of name
pay.setName(name); //use pay object to access mutator method to set name to input name value
System.out.print("Enter employee's id (LNN form): "); //prompts user to enter employee id
id = sc.nextLine(); //reads input value of id
pay.setId(id); //use pay object to access mutator method to set id to input id
System.out.print("Enter the employee's working hours: "); //prompts user to enter employee hours
hour = sc.nextInt(); //reads input value of hour
pay.setHours(hour); // set input hours
System.out.print("Enter the employee's pay rate: "); //prompts user to enter employee pay rate
rate = sc.nextInt(); //reads input value of rate
pay.setRate(rate); // set pay rate
System.out.println("Employee Data: \n"); //displays the employee data
System.out.println("Employee's Name: " + pay.getName()); //calls getName accessor method to get current value of name field and display it
System.out.println("Employee's ID: " + pay.getId()); //calls getId accessor method to get current value of id field and displays it
System.out.println("Employee's Hours: " + pay.getHours()); //calls getHours accessor method to get current value of hours field and displays it
System.out.println("Employee's Pay Rate: " + pay.getRate()); //calls getRate accessor method to get current value of rate field and displays it
}
}
Here IllegalArgumentException is thrown which is used to show that a method is passed an illegal argument.
The screenshot of program and its output is attached.
