C++ accessing container class method

I am learning C++ inheritance and I'm trying to access a container class method.

I've got an Environment class that has a public method called drawText().

The Environment class has a Robot class robot inside it:

robot = new Robot;

How can I call drawText() from inside the Robot class?

Thank you in advance!

This is what you need:

class Environment {
public:
  Environment() { }
  ~Environment() { }

  setRobot(Robot* robot) {
    robot_ = robot;
  }
  drawTest() { }

private:
  Robot* robot_;
};

class Robot {
public:
  Robot(Environment* env) {
    env_ = env;
  }

  void foo() {
    env_.drawTest();
  }

private:
  Environment* env_;
};

You can add in Robot.h Enviroment reference

//robot.h    
namespace envrNamespace    
{    
   class Environment;
};

namespace rbtNamespace
{
class Robot
{
    Environment* _parent;
    void setParent(Environment* _env) {_parent = _env;};
    Environment* getParent() {return _parent;};
    //...
}    
};

//Environment.cpp
Robot* robot = new Robot();
robot->setParent(this);
