How do you solve this issue with class and inheritance in separate files?

Question

I had this error.. when i used uses inheritance in 2 separate files..
I did the inheritance thing in the header file..

so the first header file
class MyFirstClass{
public:
there's a constructor and a destructor here..
}

so the second header file .

class MySecondClass : public MyFirstClass{
constructor and destructor
}

when I build all the three files.. the 2 separate classes and the main.cpp file..

error : expected class-name before '{' token class MySecondClass {

Answer 1

first header
second header
#include "MyFirstClass.h"
first source
#include "MyFirstClass.h"
second source
#include "MyFirstClass.h"
#include "MySecondClass.h"
main source
#include "MyFirstClass.h"
#include "MySecondClass.h"

Make sure you use #ifdef around the header code so that it is only seen once.

here is an example

Answer 3

Try

In each .cpp include the .h file according to the class name

create a main.h

- include every .h in main.h

- include main.h in main. cpp
