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.

C++

Luden [163]

Answer:

The program to this question as follows:

Program:

//header file iostream

#include<iostream> //including file for use basic function

//using name space

using namespace std;

//main method

int main() //defining main method

{

int a[3][3]; //defining two dimension array

int x,y,sum=0; //defining variables

cout<<"Enter array elements: "<<endl; //message

for(x=0;x<3;x++) // for row

{

for(y=0;y<3;y++) //for column

{

cin>>a[x][y]; //input values from user.

}

//loop for calculting sum.

for(x=0;x<3;x++)

{

for(y=0;y<3;y++)

{

sum=sum+a[x][y];//add all elements

}

cout<<"Sum: "<<sum; //print sum.

return 0;

}

Output:

Enter array elements:

1

2

3

4

5

6

7

8

9

Sum: 45

Explanation:

In the above C++ programming language code first, a header file is included then the main method is declared, inside a main method 2D array that is "a[][]", and an integer variable is defined that are "i, j, and sum". In the next line for loop is used, this loop is used two times that can be described as follows:

The first time it is used for inserting elements from user ends.
The second time, it uses the sum variable to add all array elements. and in the last print function that is "cout" is used for print sum variable value.

Create a dictionary with types as integer and string.

Airida [17]

Answer:

In c# Dictionary is the collection of keys and value .The dictionary is a generic collection class which is in the System.Collection.Generics namespace. we can represent dictionary like that Dictionary<TKey, TValue> where TKey represent the type of key and TValue is the type of TValue.

Following are the example which represent dictionary as integer and string

using System.Collections.Generic; // namespace

class Test // class test

{

static void Main() // main method

{

var ob = new Dictionary< int,string>(); // type integer and string

dictionary.Add( 2,"hello");

dictionary.Add(143,"hello1);

// The dictionary has 2 pairs.

Console.WriteLine("DICTIONARY 1 " + ob.Count);

}

Output:

DICTIONARY 1 :2

Explanation:

In this program we create a dictionary generic class which is integer and string type after that we add the elements in the dictionary by "dictionary.Add method " and finally print the count of dictionary
