The best way to create a c++ class

landing kiss

hi everybody,
to create a c++ class i can do the following

first way:

Personnage.cpp
@
#include <iostream>
using namespace std;
class Personnage
{
public:
Personnage();
~Personnage();
int getVie();
protected:
private:
int vie;
};
@
in the file "main.cpp"
i can write
@
#include <iostream>
#include "Personnage.cpp"

using namespace std;
int main()
{

cout << "Hello world!" << endl;
Personnage david;
return 0;

}
@

But it is also possible
to create a header file that i will include in the main like this :

Personnage.h
@
#ifndef PERSONNAGE_H
#define PERSONNAGE_H

class Personnage
{
public:
Personnage();
~Personnage();
int getVie();
protected:
private:
int vie;
};

#endif
@
Personnage.cpp
@
#include<iostream>
#include<string>
#include "Personnage.h"

using namespace std ;

Personnage::Personnage():vie(2)
{
//

}

Personnage::~Personnage()
{

}
int Personnage::getVie(){
return vie ;
}
@

and finally in the main.cpp
@
#include <iostream>
#include "Personnage.h"

using namespace std;
/** \brief
*
* \param
* \param
* \return
*
*/
int main()
{

cout << "Hello world!" << endl;
Personnage david;
//cout<<david.getVie()<<endl;
return 0;

}
@
so i want to know what is the best way to create a c++ class is it good to include directly a sourcefile.cpp which contains the definition of the class ? thanks

Edit: please use @ tags around code sections; Andre

It is better to split source code into several files and to rely on header files. It is also recommended to use #include macro guards to make sure that the file was been include only once (aka to avoid double or multiple inclusion).

Hi,
I have an example explaining the right way to create a C++ program.

The source code can be downloaded here :

thanks ! effectively it is better to avoid several inclusion
