Question

10.13 LAB*: Warm up: Online shopping cart (Part 1)

(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 constructor
• Public 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

(2) In main(), prompt the user for two items and create two objects of the ItemToPurchase class. Before prompting for the second item, call cin.ignore() to allow the user to input a new string. (2 pts)

Ex:

Item 1
Enter the item name:
Chocolate Chips
Enter the item price:
3
Enter the item quantity:
1

Item 2
Enter the item name:
Bottled Water
Enter the item price:
1
Enter the item quantity:
10

(3) Add the costs of the two items together and output the total cost. (2 pts)

Ex:

TOTAL COST
Chocolate Chips 1 @ $3 = $3
Bottled Water 10 @ $1 = $10

Total: $13

#include <iostream>
using namespace std;

#include "ItemToPurchase.h"

int main() {

/* Type your code here */

return 0;
}

Answer 1

output:

my code:

#include <iostream>
using namespace std;
/*Below make a class with a private member ,mutators & accessors*/
class ItemTOPurchase{
private:
/*Below we define 3 private member*/
string itemname;
int itemprice;
int itemQuantity;
public:
/*default constructor with value 0*/
ItemTOPurchase()
{
itemname=" ";
itemprice=0;
itemQuantity=0;
}
/*below we make 3 mutators functions for set the value of private member*/
void SetName(string n) /*this function is used for set itemname */
{
itemname=n;
}
void SetPrice(int p) /*this function is used for set itemprice */
{
itemprice=p;
}
void SetQuantity(int q) /*this function is used for set itemQuantity */
{
itemQuantity=q;
}
  
/*below we make 3 accessors functions for set the value of private member*/
string GetName() /*this function is used for get itemname */
{
return itemname;
}
int GetPrice() /*this function is used for get itemname */
{
return itemprice;
}
int GetQuantity() /*this function is used for get itemname */
{

/*here we print total cost we use of accessors of class*/
cout<<"TOTAl COST"<<endl;
cout<<I1.GetName()<<" "<<I1.GetQuantity() <<" @ " <<I1.GetPrice()<<" = "<<I1.GetPrice()*I1.GetQuantity()<<endl;
