How does modularity provide flexibility in a structured programming design?

Elanso [62]

Modular programming is the process of subdividing a computer program into separate sub-programs. Modularity provides flexibility in a structured programming design the following way: Modularity enables multiple programmers to work on a program at the same time. Correct answer: A

It provides developers flexibility in module maintenance.This makes the program easier to read and understand.

Write a CashRegister class that can be used with the RetailItem class that you wrote in Chapter 6's Programming Challenge 4. The

lys-0071 [83]

Answer:

Following are the code to this question:

import java.util.*; //import package for user input

class RetailItem//defining class RetailItem

{

private String desc;//defining String variable

private int unit;//defining integer variable

private double prices;//defining double variable

RetailItem()//defining default Constructor

{

//Constructor body

}

Output:

The Sub Total value: 199.75

The Sales Tax value: 11.985

The Total value: $211.735

Explanation:

In the above code three class "RetailItem, CashRegister, and Main" is defined, in the class "RetailItem", it defines three variable that is "desc, unit, and prices", inside the class "get and set" method and the constructor is defined, that calculates its value.

In the next step, class "CashRegister" is defined, and inside the class parameterized constructor is defined, which uses the get and set method to return its value.

In the next step, the main class is declared, in the main method two-class object is created and calls its method that are "getSubtotal, getTax, and getTotal".

There is some technical error that's why full code can't be added so, please find the attached file of code.

Write a program that prompts the user to enter two characters and display the corresponding major and year status. The first cha

nydimaria [60]

Answer:

import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Please enter two characters: ");
String inputStr = input.nextLine();
if(inputStr.charAt(0) == 'B' || inputStr.charAt(0) == 'b'){
System.out.println("Biology");
}
else if(inputStr.charAt(0) == 'C' || inputStr.charAt(0)== 'c'){
System.out.println("Computer Science");
}
else if(inputStr.charAt(0) == 'I' || inputStr.charAt(0) == 'i')
{
System.out.println("Information Technology and Systems");
}
else{
System.out.println("Invalid major");
}
int num = Character.getNumericValue(inputStr.charAt(1));
if(num >= 1 && num <= 4){
switch (num){
case 1:
System.out.println("freshman");
break;
case 2:
System.out.println("sophomore");
break;
case 3:
System.out.println("junior");
break;
case 4:
System.out.println("senior");
break;
}
}
else{
System.out.println("Invalid year status");
}
}
}

Explanation:

The code consists of two main parts. The part 1 is to validate the input major and print out the major according to the input character (Line 10 -22). If the input character is not matched with the target letters, a message invalid major will be displayed.

The part 2 is to validate the year status to make sure it only fall within the range of 1-4 (Line 26 -45). If within the range, the program will display the year major accordingly. If not a message invalid year status will be displayed.

Suppose we wanted to make change for purchases and wanted to use the least number of coins possible. Here is a greedy algorithm:

love history [14]

Answer:

Explanation:

The following code is a Python function that takes in the amount of change. Then it uses division and the modulo operator to calculate the number of coins that make up the changes, using the greatest coin values first.

import math

def amountOfCoins(change):

print("Change: " + str(change))

quarters = math.floor(change / 0.25)

change = change % 0.25

dimes = math.floor(change / 0.20)

change = change % 0.20

pennies = math.floor(change / 0.01)

print("Quarters: " + str(quarters) + "\nDimes: " + str(dimes) + "\nPennies: " + str(pennies))
