PLEASE ADD THE FOLLOWING SPECIFICATION TO THE PROGRAM I have add some of please check if they are working and please post the output as well

// Specification C2 - Dynamic Array Create an array on the heap. Initialize it to 1 element. You will add elements as necessary.

3. // Specification C3 - Resize Array

Allows you to add records to the end of the inventory data structure you created. This is activated with the first menu option Above. Create a pTmp pointer variable for the new data structure. You will also subtract elements from the end as well.

//Specification B2 -RandNo Class

Create a random number class, RandNo. You will use this to re-turn the random number for the Wholesale cost (but you can make it flexible for other stuff too if you want). It should know seed initialization state and randomly set it once if needed.

// Specification B4 - Inventory Entry Input Validation Apply the first three validation rules from Table 1 to Add new item and Edit item (Spec A1) menu selections. Re-prompt if in- correct input. Create an InVal class or function to perform this check.

IMPORTANT ONES A2, A3! I HAVE NO IDEA HOW TO DO THESE TWO PLEASE HELP

// Specification A2 - Overload operator

Overload the stream extraction operator somewhere in your pro- gram. Im guessing the Inventory struct is the easiest place to do this.

// Specification A3 - Overload operator Overload the stream insertion operator for the RandNo class. This will be how you will enter a user specified seed. This method will prompt the user and use the integer value they provide as the random number seed - overwriting the time value if needed.
