7.10.1: LAB: Product struct

Given main(), build a struct called Product that will manage product inventory. Product struct has three data members: a product code (string), the product's price (double), and the number count of product in inventory (int). Assume product code has a maximum length of 20.

Implement the Product struct and related function declarations in Product.h, and implement the related function definitions in Product.c as listed below:

Product InitProduct(char *code, double price, int count) - set the data members using the three parameters
Product SetCode(char *code, Product product) - set the product code (i.e. SKU234) to parameter code
void GetCode(char *productCode, Product product) - return the product code in productCode
Product SetPrice(double price, Product product) - set the price to parameter product
double GetPrice(Product product) - return the price
Product SetCount(int count, Product product) - set the number of items in inventory to parameter num
int GetCount(Product product) - return the count
Product AddInventory(int amt, Product product) - increase inventory by parameter amt
Product SellInventory(int amt, Product product) - decrease inventory by parameter amt

Ex. If a new Product struct is created with code set to "Apple", price set to 0.40, and the count set to 3, the output is:

Name: Apple Price: 0.40 Count: 3

Ex. If 10 apples are added to the Product struct's inventory, but then 5 are sold, the output is:

Name: Apple Price: 0.40 Count: 8

Ex. If the Product struct's code is set to "Golden Delicious", price is set to 0.55, and count is set to 4, the output is:

Name: Golden Delicious Price: 0.55 Count: 4
