Question

(1) Create three files to submit:

ItemToPurchase.h - Class declaration
ItemToPurchase.cpp - Class definition
main.cpp - main() function
Build the ItemToPurchase class with the following specifications:
Default constructorPublic class functions (mutators & accessors)
SetName() & GetName() (2 pts)
SetPrice() & GetPrice() (2 pts)
SetQuantity() & GetQuantity() (2 pts)
Private data members
string itemName - Initialized in default constructor to "none"
int itemPrice - Initialized in default constructor to 0
int itemQuantity - Initialized in default constructor to 0

Answer 1

We have the files and codes below with appropriate comments

Step-by-step explanation:

ItemToPurchase.h:

#pragma once

#ifndef ITEMTOPURCHASE_H_INCLUDED

#define ITEMTOPURCHASE_H_INCLUDED

#include<string>

#include <iostream>

using namespace std;

class ItemToPurchase

{

public:

//Declaration of default constructor

ItemToPurchase();

//Declaration of SetName function

void SetName(string ItemName);

//Declaration of SetPrice function

void SetPrice(int itemPrice);

//Declaration of SetQuantity function

void SetQuantity(int itemQuantity);

//Declaration of GetName function

string GetName();

//Declaration of GetPrice function

int GetPrice();

//Declaration of GetQuantity function

int GetQuantity();

private:

//Declaration of itemName as

//type of string

string itemName;

//Declaration of itemPrice as

//type of integer

int itemPrice;

//Declaration of itemQuantity as

//type of integer

int itemQuantity;

};

#endif

ItemToPurchase.cpp:

#include <iostream>

#include <string>

#include "ItemToPurchase.h"

using namespace std;

//Implementation of default constructor

}

//Implementation of SetName function

{

}

//Implementation of SetPrice function

{

this->itemPrice = itemPrice;

}

//Implementation of SetQuantity function

{

}

//Implementation of GetName function

string ItemToPurchase::GetName()

{

}

//Implementation of GetPrice function

}

//Implementation of GetQuantity function

{

}

int totalCost = 0;

//Display statement for Item1

cout << "Item 1:" << endl;

cout << "Enter the item name : " << endl;

//call the getline function

//Display statement
