Question
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. + means public and - means private:
ItemToPurchase
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
Note: For unit testing purposes, do not implement any input or output inside your set or get functions.
If you get a compilation error in a unit test, it is likely that the order of your parameters, the types of your parameters, or the name of your function does not match the specification. This includes the const keyword at the end of get functions.
in printItemCost(), print itemName itemQuantity @ $itemPrice = $itemPrice * itemQuantity
In main, prompt the user for two items and create two objects of the ItemToPurchase class. Use getline to input the item name so the user can input more than one word. Before prompting for the second item, call cin.ignore() to clear the newline before the next call to getline.
Call printItemCost() on each of the two items
At the top of main, type cout << fixed << setprecision(2) to display your doubles as money.
it keeps saying my stuff is not declared in the scope. Please help.
Add getPrice() * setQuantity from each item and output the total cost.
