Please help me solve this problem ASAP!!! and please make the required files as indicated in the end of the problem.

Book Chapters

Write a program that encapsulates a Book with its title and its Chapters name with the pages in each chapter.

Chapter

A Chapter object should get instantiated using the name of the Chapter and the number of pages. The name can be a maximum of 50 characters long and the pages of the chapters cannot be more than 200. If any of this information is not provided or if they are invalid, the object is created in an invalid state.

A Chapter is displayed as follows (if Valid):

• Name in 50 spaces, filled with dots '.', left-justified
• Number of pages in 3 spaces right-justified
• Newline

If the chapter is invalid, it should just print: "invalid Chapter" and go to newline.

For example if the Chapter name is Java and it is 60 pages, it should print as follows:

Java.............................................. 60

Book

A Book is created using its name, number of chapters and an array of Chapters ( with "number of chapters" elements).

The length of the name or the number of chapters is unknown.

The following are the public functions required for the Class Book.

bool isEmpty()const;

returns true if the Book is empty or invalid, otherwise, it returns false;

Book& addChapter(const char* chapter_name, int noOfPages);

Adds a Chapter to a Book only if the name and noOfPages are valid values (to create a Chapter with).

void display()const;

Displays the Book as follows, if it is valid:

• prints "Book Name: "
• prints the book name value
• NEWLINE
• prints "No of chapters: "
• prints the number of chapters
• prints all the Chapters in individual lines If the book is invalid it will print:
• otherwise, prints "Invalid book object";

Note

Make sure all the allocated memory is deleted when the object goes out of scope.

Tester program:

The output:
