I recently switched to C++ after using Java for a good amount of time. However, I have some difficulty grasping the entire concepts of using header files along with class files.

Firstly, aren't headers just like interfaces in the OOP context?

Secondly if I have the following piece of code why do I get an error:

    //CExample.h
    //--START OF HEADER--         

    #ifndef CEXAMPLE_H
    #define CEXAMPLE_H
    #include <string>

    class CExample{
    private:
       string name;
    public:
       CExample();
      ~CExample();
       string getName();
    };
    #endif

   //--End of Header--


   //CExample.cpp
   //--Start of class file--

   #include "CExample.h"
   string CExample::getName()
   {
       return name;
   }
   //--End of class file--

I get the error: 'string' does not name a type.

So as a summary of my confusion I have the following questions:

1) What's the best and healthy way of using includes in the headers.

2) What's the concrete difference between using "" and <> for includes. (Yes I have read plenty of c++ tutorials but the explanations are somewhat vague -- they say it depends on the directory location etc -- I would like some c++ veteran to make a clear statement if possible)

3)Are there are naming conventions enforced in C++? For example in Java, you need to have the class name match the file name in which is is defined.

    Voting to close this as question 1) alone is too broad. Other unrelated questions have duplicates as well. Since this isn't a chat room or forum, please try to focus on a specific question. – Drew Dormann Jun 23 '15 at 13:30

For question 3, no need to make class name and file name the same, but you must keep cpp file and header file have the same name
