# 해결

## 아이디어1: map과 OOP를 사용
```cpp
class ICommand
{
  public:
  virtual void execute() const = 0;
  virtual void ~ICommand(){};
};

class KeyUpCommand : public ICommand
{
  DWORD key_; //not suare about win api here
  public:
  KeyUpCommand(key) : key_(key) {};
  virtual void execute() const
  {
     keyUp(key_);
  };
};

class KeyDownCommand : public ICommand
{
  DWORD key_; //not suare about win api here
  public:
  KeyDownCommand(key) : key_(key) {};
  virtual void execute() const
  {
     keyDown(key_);
  };
};


int main()
{
  std::map<std::string, ICommand *> commands;
  commands["t-"]=new KeyUpCommand(VK_TAB);

  //execute now
  std::map<std::string, ICommand *>::const_iterator iter = commands.find(_specialKey);
  iter->second->execute();
};
```
