1. Complete the addBook function

When a new book is added to the inventory, the program will search the bookTitle array for an element that is set to an empty string or the null terminator. If the element contains an empty string or a null terminator, it means there isnt a string stored there. (Because the arrays are global, all their elements will be automatically initialized to zero.)

Once an empty element is found in the bookTitle array, the books data may be stored in each of the other arrays by using the same subscript. For instance, if the title of the book is stored in bookTitle[7], its ISBN number will be stored in isbn[7], its authors name will be stored in author[7], its publishers name will be stored in publisher[7], the date the book was added to the inventory will be stored in dateAdded[7], the quantity of books on hand will be stored in qtyOnHand[7], the books wholesale price will be stored in wholesale[7], and the books retail price will be stored in retail[7].

The addBook function is currently a stub function. Modify it so it performs the following steps:

First the function should search the bookTitle array for an empty element. As described above, the function should look for an element containing an empty string or the null terminator. If no empty element is found, it means the array is full. In that case, the function should display a message indicating that no more books may be added to the inventory, and then terminate.

Once an empty element is found in bookTitle, the function should ask the user to enter the following items:

Book title

ISBN number

Authors name

Publishers name

The date the book was added to the inventory

The quantity of the book being added

The wholesale cost of the book

The retail price of the book

Each item above should be added to the appropriate array. Note that the wholesale cost and retail price is for a single copy of the book. Also, remember that the date should be entered in the form MM-DD-YYYY, where MM is the month, DD is the day, and YYYY is the year.

Test your code with below information.

2. Complete the lookUpBook Function

The lookUpBook function is currently a stub function. Modify it so it performs the following tasks:

It should ask the user for the title of a book. This is the book that is to be looked up in the inventory database.

The function should search the bookTitle array for a title that matches the one entered by the user. If no match is found, the function should display a message indicating that the book is not in inventory, and terminate. If the book is found, the function should call bookInfo, passing the correct data as arguments.

3. Complete the editBook Function

The editBook function is currently a stub function. Modify it so it performs the following tasks:

It should ask the user for the title of a book. This is the book whose data are to be edited.

The function should search the bookTitle array for a title that matches the one entered by the user. If no match is found, the function should display a message indicating that the book is not in inventory, and terminate. If the book is found, the function should call bookInfo, passing the correct data as arguments.

The function should ask the user which of the fields he or she wished to change. The user is then allowed to enter new values for the selected field. These new values are saved in the arrays, replacing the old values

4. Complete the deleteBook Function

The deleteBook function is currently a stub function. Modify it so it performs the following

tasks:

It should ask the user for the title of a book. This is the book that is to be deleted from the inventory database.

The function should search the bookTitle array for a title that matches the one entered by the user. If no match is found, the function should display a message indicating that the book is not in inventory, and terminate. If the book is found, the function should call bookInfo, passing the correct data as arguments.

The function should ask the user if they are sure the books data are to be deleted from the inventory. If so, the books title (stored in the bookTitle array) is to be set to an empty string or the null terminator. The ISBN number (stored in the isbn array) should be set to an empty string or the null terminator as well.
