Thread: C++ help

Bien Sur

Code:

#ifndef BODY_H
#define BODY_H

#include "Object.h"
#include "Limb.h"

class Body{
    public:
        Body();  // parameterless default constructor
	private:
		Object torso;
		Object neck;
		Object head;
		Limb leftarm;
		Limb rightarm;
		Limb leftleg;
		Limb rightleg;
};

#endif

Hmm, don't know why the indents came out like that

Ok,
You're allocating the objects dynamically (using new)
so the members in Body.h need to be pointers
(new returns a pointer to the object on the heap)

Code:

    private:
        Object* torso;
        Object* neck;
        Object* head;
        Limb* leftarm;
        Limb* rightarm;
        Limb* leftleg;
        Limb* rightleg;

Either that,
or change how you allocate the objects in Body.cpp

Instead of

Code:

Neck = new Object();

Use

Code:

Object Neck();

(whether you allocate dynamically or not is down to exactly how you're going to be using the objects later on - if they're large, dynamic's always a good idea, as there's limited space on the stack)

Ooooh. Damn university taught me java, is there ever a more useless language? Is there a good C++ book like 'C in a nutshell'?

Hey, it compiles!

Bjarne Stroustrup (the guy who developed C++) has written a few books

Eg.
http://www.amazon.co.uk/C%2B%2B-Prog...0291486&sr=8-2
His stuff tends to be very involved, though

Any good book store should have loads of C++ books,
over a wide range of skill levels

but to be honest, most of the info is online anyway
check out

no probs

If you've gone the dynamic way, remember to free objects after you've finished with them
else you'll have a memory leak

see these for dynamic memory / pointers

Oh right, I have to write a destructor. Damn java's garbage collector made me loose everything that I knew about C++.
