Coding Conventions

The following coding conventions should be used for all assignments.

Have a comment section at the top of your files with your name, the assignment number and the date the code was written. You may add more to the top comment if you wish.
Put a blank line between each function body (including between main and user defined functions), between the header section (#include and using namespace) and the function prototype section, and between the function prototypes and the main function.
Indent all blocks such as if statements or loops with at least two spaces. For example, your if statements should appear as:
```
if(a == b)
{
  a = a * 2;
  b = b - 1;
}
```
NOT as:
```
if(a == b)
{
a = a * 2;
b = b - 1;
}
```
If you use vim on Sleipnir, it will indent such blocks automatically for you.

Assignment

The purpose of this assignment is to create a structure called ProductInfo for a small inventory control system. You will also be using a dynamic array to track the collection of products in the inventory. You MUST use a dynamic array for this assignment. Any assignment that does not use new/delete will have points deducted.

The ProductInfo structure must have the following pieces of data:

A C-style string for the product name (you may choose the length for this string)
A C-style string for the product description (you may choose the length for this string)
A 13 character C-style string for the UPC (Universal Product Code)
An integer for how many of that product are in stock

You will have the following two void functions to manipulate ProductInfo objects:

addProduct - Takes a single ProductInfo object as a parameter. It will set the name, description, UPC and amount in stock for that product by prompting the user for this information.
showProduct - Takes a single ProductInfo object as a parameter. It will display the name, description, UPC and amount in stock for that product.

Your main function will do the following steps:

Prompt the user for the number of products they wish to add to the inventory and read the response in.
Validate that the integer given by the user is greater than 0. Points will be deducted if you do not validate the user's input.
Dynamically allocate an array of ProductInfo objects using the integer given by the user.
For each object in the ProductInfo array, call addProduct.
For each object in the ProductInfo array, call showProduct.
Deallocate the array.
