The application

[Znurre]

So, lately these forums have been rather dead.
I thought we needed some fun threads for a change (from a nerds perspective), so here you go.
Some of you might have played the game where you fold a paper and each person gets to draw one part of a person, and in the end you unfold the paper and you get a weird looking character.

I thought of something similar, but with programming.
The rules are simple:

• Programming language is C/C++, but feel free to extend it with Python, Lua, QtScript etc. if you have the knowledge, using libraries like tolua (http://www.tecgraf.puc-rio.br/~celes/tolua/).
• Each poster should only add enough code to make the code compile, to avoid one person deciding the whole focus of the project.
• Feel free to use any library that is cross platform, but if you add a dependency it could be good if you state it.
• When you extend the code with a new class, keep each class in separate [code] sections to ease readability.
• Should compile with gcc on at least Windows and Linux.
• Only add code, don't change or remove others.
• Have fun!

So, I start with the basics:

main.cpp:

int main( int argc, char **argv )
{

}

Go go go!

main.cpp:

#include <iostream>

int main( int argc, char **argv )
{
   std::cout << "Hello Ra !" << std::endl;
}

Hey, we could make a game, with SDL or SFML !

[Znurre]

main.cpp:

#include <iostream>

int main( int argc, char **argv )
{
   std::cout << "Hello Ra !" << std::endl;
   std::cout << "Enter your player name: ";
   
   char name[ 32 ];
   std::cin >> name;
}

[kidanger]

main.cpp:

#include <iostream>

#include "player.hpp"

int main( int argc, char **argv )
{
   std::cout << "Hello Ra !" << std::endl;
   std::cout << "Enter your player name: ";
   
   char name[ 32 ];
   std::cin >> name;
   Player player(name);
}

player.hpp:

#ifndef PLAYER_HPP
#define PLAYER_HPP

#include <iostream>

class Player
{
   public:
      Player();
      Player(char* n) { name = n; }
      
      std::string GetName() { return name; }
   
   private:
      std::string name;
};

#endif

I'm a beginner in C++, but I think the usage of char[] is not recommended, is it ?

Well, in my scenario, char *name; would cause a segfault because I would try to assign data to a NULL pointer with cin.
In your case, char * is a pointer to my char array.

Or do you mean "not recommended" as in "not preferred" to for example std::string?

PS: You don't happen to be a C# programmer, do you?
Your coding style slightly hints that you are.

main.cpp:

#include <iostream>

#include "player.hpp"

int main( int argc, char **argv )
{
   std::cout << "Hello Ra !" << std::endl;
   std::cout << "Enter your player name: ";
   
   char name[ 32 ];
   std::cin >> name;
   Player player(name);
   player.punish();
}

player.hpp:

#ifndef PLAYER_HPP
#define PLAYER_HPP

#include <iostream>

class Player
{
   public:
      Player();
      Player(char* n) : banned( false ) { name = n; }
      
      std::string GetName() { return name; }

      void punish()
      {
             //TODO
      }
   
   private:
      std::string name;
      bool banned;
};

#endif

Yes, as "not preferred". >.<

No, I've never learnt C#. Which hints ?

main.cpp:

#include <iostream>

#include "player.hpp"

int main( int argc, char **argv )
{
   std::cout << "Hello Ra !" << std::endl;
   std::cout << "Enter your player name: ";
   
   char name[ 32 ];
   std::cin >> name;
   Player player(name);
   player.punish();
}

player.hpp:

#ifndef PLAYER_HPP
#define PLAYER_HPP

#include <iostream>
#include <cstdlib> //rand()

class Player
{
   public:
      Player();
      Player(char* n) : banned( false ) { name = n; }
      
      std::string GetName() { return name; }

      void punish()
      {
	 //TODO
	 if(rand()%3 == 2)
	 {
	    std::cout << "Hacker detected. " << name << " is now banned." << std::endl;
	    banned = true;
	 }
      }
   
   private:
      std::string name;
      bool banned;
};

#endif

OMG you're right (?)

Maybe I should open an OpenGL performance thread and we all try to figure out what's the issue, because I couldn't find it.

I tried profiling it, but cachegrind just hung

For example your getter methods
Usually in C++, people use camel case method names without a first capital letter.
However, in all Microsoft's .NET languages, method names (and properties) starts with a capital letter.

For example:

    public class EmailLogObject
    {
        public short EmailType { get; set; }
    }
