Question

A. Create a Dollar currency class with two integer attributes and one string attribute, all of which are non-public. The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part. The string attribute will represent the currency name.

B. Create a CIS22C Dollar derived/inherited class with one additional non-public double attribute to represent the conversion factor from/to US Dollar.

• The value of the conversion factor can be defaulted in the class definition based on 1 USD = 1.36 C2D or 1 C2D = 0.74 USD.
• Also, 1000 of C2D fractional parts equals 1 C2D whole part.

C. In your two currency classes, add public methods for the following:

• Default Construction (i.e. no parameters passed)
• Construction based on parameters for all attributes
• Copy Constructor and/or Assignment, as applicable to your programming language of choice
• Destructor, as applicable to your programming language of choice
• Setters and Getters for all attributes
• Adding two objects of the same currency
• Subtracting one object from another object of the same currency
• Comparing two objects of the same currency for equality/inequality
• Comparing two objects of the same currency to identify which object is larger or smaller
• Print method to print details of a currency object
• In your derived class only, methods to convert USD objects to C2D and vice versa

D. Create a Wallet class with one attribute - an array of two Dollar references / pointers and the following methods to demonstrate polymorphism of the currencies:

• A default Constructor which sets
  • the first element of the array to a zero value Dollar object
  • the second element of the array to a zero value CIS22C Dollar object
• A Destructor, as applicable to your programming language of choice
• Methods to add or subtract
  • USD objects to/from the first element only and
  • C2D objects to/from the second element only
• Methods to compare if the value of either element is greater or smaller than an input value
• A method to Print the values of the two elements in the Wallet

E. In your main:

• Create a Wallet object
• Provide the user a main menu to add/ subtract/ compare the Dollar and CIS22C Dollar values in the Wallet as well as print the contents of the Wallet
• You can use a second level menu choice to allow the user to select currency type
• Based on user choice, create either UD or C2d objects as needed to perform the desired operations.
• The main menu should be run in a loop until the user selects the Exit option
• There is no sample output - you are allowed to provide user interactivity as you see fit and programs will be graded for clarity of interaction

Answer 1

Here there four questions on above the given time very limited. plz make sure understand the given code.

cloud plz check the code for Dollar currency.

#include<iostream>
#include<conio.h>
#include<string.h>
using namespace std;

class Dollar_currency
{
//Access specifier
private:
//Data members
int rupee, paisa;
string num1, num2;

public:
Dollar_currency(); //Default Constructor
Dollar_currency(int, int); //Parameterised Cosntructor

double getDOllar(); //Method to get USDdollar
int getReupee();
int getPaisa();
string getNum1();

void setReupee(int);
void setPaisa(int);
void setNum1(string);
void setNum2(string);

};

plz make sure maintain some fix space while writting above programs .

sorry for the inconvince i have not written th e code for the wallet class there is no time .

plz check the output for the above code .

Output:

US dollar is : 10.25 USD

US Note : Ten dollar

CIS22C dollar is : 13.94 C2D

Copy Constructor :

CIS22C dollar is : 13.94 C2D

2nd Object Details :

US dollar is : 52.2 USD

US Note : Fifty Two dollar

CIS22C dollar is : 70.992 C2D

Addition of two objects is : 84.932

Substraction of two objects : 57.052

Object Comparision

Object 2 is greater than Object 1
