C++ Write a function void manage(string library, string book, string author) that reads into 3 files library.txt and book.txt and author.txt.

In there:

The file library.txt contains information about the libraries, including: the first line contains a positive integer N which is the number of libraries surveyed. The next N lines each contain 6 values separated by a space. For each row, the first value is the name of the Library (the name of the Library is unique), the other 5 values are 5 positive integers, which are the IDs of the 5 books in that library.

Example:

3

LA 1 2 3 4 5

LB 5 3 1 2 4

LC 4 1 5 2 3

The file book.txt contains information about the books, including: the first line contains a positive integer M which is the number of titles in all libraries. The next M lines each contain 3 values (separated by a space) that have the following meaning: the first value is a positive integer representing Book Number (ID - ID is unique), the 2nd value is the year of manufacture and the last value is the category.

Example:

5

1 2000 A

2 2001 B

3 1993 D
