Question

C

(1) Create three files to submit:

• ItemToPurchase.h - Struct definition and related function declarations
• ItemToPurchase.c - Related function definitions
• main.c - main() function

Build the ItemToPurchase struct with the following specifications:

• Data members (3 pts)
  • char itemName [ ]
  • int itemPrice
  • int itemQuantity
• Related functions
  • MakeItemBlank() (2 pts)
    • Has a pointer to an ItemToPurchase parameter.
    • Sets item's name = "none", item's price = 0, item's quantity = 0
  • PrintItemCost()
    • Has an ItemToPurchase parameter.

Ex. of PrintItemCost() output:

Bottled Water 10 @ $1 = $10

(2) In main(), prompt the user for two items and create two objects of the ItemToPurchase struct. Before prompting for the second item, enter the following code to allow the user to input a new string. c is declared as a char. (2 pts)

c = getchar();
while(c != '\n' && c != EOF) {
   c = getchar();
}

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
