Homework SourseI need assistance creating a C code I need you to help me cr
I need assistance creating a C++ code. I need you to help me create the input and output functions that will allow a user to enter a title of a book and the author with spaces in which you\'ll need to use the getline function for these. After you create these classes I need you to go to my library class. The library class allows:
1) The input of an additional book to be entered into the sytem.
2) Listing the current books in the order of which they are currently stored.
3) Outputs the number of books in the library.
4) Outputs the total number of pages in the library.
5) Sorts the books in the library by copyright date and outputting them to the screen. (Ascending order)
6) Sorts the books in the library by title and outputting them to the screen. (Ascending order)
7) Search for a particular book by title and outputting the information on that book (author, date, pages)
8) Search for a particular author and outputting all the books by that author and their information (title, date, pages)
9) Removal of a book.
The self.txt is a backup file for the library and will need a load and save function in which the system will be able to load all current information from as well as saving new information to. For example if there is a new book added in, it will be saved to the shelf.txt file. Please do not change the code inside the main.cc unless something does not work!!! Below is the code that I have so far:
main.cc

#include <iostream>

#include \"book.h\"
#include \"library.h\"
int menu();
using namespace std;
int main(){

Book tmp;
string tmpstring;
int choice;
ifstream ifs;
ofstream ofs;
ifs.open(\"shelf.txt\");
if(!ifs.fail()){
mybooks.load(ifs);
ifs.close();
}
// start the user interaction menu
do{
choice = menu();
switch(choice){
case 1:
cin>>tmp;
mybooks.addbook(tmp);
break;
case 2:
mybooks.showall(cout);
break;
case 3:
cout<<\"Currently there are \";
cout<<mybooks.size();
cout<<\" books in your library.\ \";
break;
case 4:

cout<<\" total pages in your library.\ \";
break;
case 5:
mybooks.sort_by_date();
break;
case 6:
mybooks.sort_by_title();
break;
case 7:
cout<<\"Enter the title of the book:\ \";
if(cin.peek() == \'\ \')
cin.ignore();
getline(cin,tmpstring);
mybooks.find_title(tmpstring);
break;
case 8:
cout<<\"Enter the author\'s full name:\ \";
if(cin.peek() == \'\ \')
cin.ignore();
getline(cin,tmpstring);
mybooks.find_author(tmpstring);
break;
case 9:
cout<<\"Enter title to remove:\ \";
if(cin.peek() == \'\ \')
cin.ignore();
getline(cin,tmpstring);
mybooks.remove(tmpstring);
case 0:
cout<<\"Leaving your library now.\ \";
break;
default:
cout<<\"Not a valid option.\ \";
break;
} // bottom of the switch
}while(choice != 0);
// Now saving the library
ofs.open(\"shelf.txt\");
mybooks.save(ofs);
ofs.close();
return 0;
}
// The menu function which returns the user\'s choice
int menu() {
int choice;
cout<<\"Please chose from the following options:\ \";
