C++ please fix my code involving ifstream a& ofstream in Save and Load functions in Q5 and also fix the errors in code in Q4. I have added any other header or any other cpp files so you cannot test it, sorry.

// READ BEFORE YOU START:

// You are given a partially completed program that creates a list of animals.

// Each animal has the corresponding information: Category, breed, subcategory, name and age.

// In the Animals.h file, you will find the definition for this enum 'category'and 'subcategory'.

// Animals on the list can be 2 different 'ctegories' : either a canidae or a felidae.

// The classes Dog and Cat are subclasses of the Canidae and Felidae class respectively.

// Both of these classes will have their own use of the virtual display method.

//

// To begin, you should trace through the given code and understand how it works.

// Please read the instructions above each required function and follow the directions carefully.

// If you modify any of the given code, the return types, or the parameters, you risk failing the automated test cases.

//

// You are to assume that all input is valid:

// Valid name: String containing alphabetical letters beginning with a capital letter

// Valid breed: String containing alphabetical letters beginning with a capital letter

// All input will be a valid length and no more than the allowed amount of memory will be used
