Task: Create a hash table of a candy stores inventory. The table will be an array of structures. The program should permit price checks and should allow item quantities to be increased or decreased.
Input: The tables data values will be read from a text file. The input file is La.txt. The program will initialize the table by using a hash function to place each structure in an appropriate array location. The data structure to use is:
struct Candy
{
string IDcode; // 4-char alphanumeric code
string itemName; // name/description of the candy
double quantity; // quantity on hand, in pounds
double price; // price per pound
};
You may decide on the array size. Create an appropriate hash calculation to assign each element into the array. Decide how collisions will be handled; for this assignment, use a method other than a linear probe.
Processing: Provide a menu for the user. Options should include:
availability check: is an item in stock (quantity > 0), and if so, what is its price?
purchase: decrement the quantity by some amount
delivery: increase the quantity
inventory: print the complete inventory to a hard copy report
