Start here:

#include <iostream>
#include <string>
#include <sstream>
 
using namespace std;
 
class SimpleBook {
public:
   SimpleBook();
   SimpleBook(string aName, string aIdentifier, string text = "");
   string ToString() const;
   string GetName() const;
   string GetIdentifier() const;
   string GetText() const;
   void SetName(string aName);
   void SetIdentifier(string aIdentifier);
   void SetText(string aText);
   string Read() const;
private:
   string bookName;
   string bookIdentifier;
   string bookText;
};
 
SimpleBook::SimpleBook() {
   bookName = "none";
   bookIdentifier = "none";
   bookText = "none";
}
 
SimpleBook::SimpleBook(string aName, string aIdentifier, string aText) {
   bookName = aName;
   bookIdentifier = aIdentifier;
   bookText = aText;
}
 
string SimpleBook::ToString() const {
   ostringstream aStream;
   aStream << "Title: " << bookName << " Identifier: " << bookIdentifier << " Text: " << bookText;
   return aStream.str();
}
 
string SimpleBook::GetName() const {
   return bookName;
}
 
string SimpleBook::GetIdentifier() const{
   return bookIdentifier;
}
 
string SimpleBook::GetText() const {
   return bookText;
}
 
void SimpleBook::SetName(string aName) {
   bookName = aName;
}
 
void SimpleBook::SetIdentifier(string aIdentifier) {
   bookIdentifier = aIdentifier;
}
 
void SimpleBook::SetText(string aText) {
   bookText = aText;
}
 
string SimpleBook::Read() const {
   return bookText;
}
 
int main() {
   SimpleBook aBook;
   SimpleBook otherBook("Book of Mormon","AA 1","I Nephi having..");
 
   cout << otherBook.ToString() << endl;
 
   cout << "Read some books:" << endl;
 
   cout << "From: " << otherBook.GetIdentifier() << ": " << otherBook.Read() << endl;
   cout << "From: " << aBook.GetIdentifier() << ": " << aBook.Read() << endl;
 
   system("pause");
 
 
   return 0;
}
