Is it possible to declare an object from a different class to be a member of a class? If so then how.

    class foo{int foo;};class bar{foo my_foo;};    

Here is my code:

    class Obj{public:	Obj(char file[128]);	float vertArray[36];	void LoadBasicInfo();	void LoadFileData();		int GetNumVerts();	int GetNumFaces();	int GetNumVertNormals();private:	typedef float vertex[3];	typedef float normals[3];		vertex *verts;	normals *norms;	bool fileLoad;	char fileName[40];		int numVerts;	int numVertNormals;	int numFaces;};class Foo{	Obj obj("box.obj");};    

VC gives the following compiler error:

error C2059: syntax error : ''string''

Im not sure if Im right but, I think you need to change:

Obj(char file[128]);

to:

Obj(char *file);

Not quite.

In a class declaration you may only declare how the class is built up, but execute code.(only exception inline functions)

Btw: The declaration with the Obj(char file[128]); is absolutely valid.

This should work:

class Foo
{
Foo (void); // Or something
Obj obj;
};

in the header and then

Foo::Foo( void ):
Obj("whateverstringyouwant")
{
// other init stuff
}

By the way, if you wondered why sometimes you were able to use objects in your classes this is because the class of the object had a constructor using no arguments or no constructor at all (which results in a default public constructor)

class myclass
{
void myclass(void);
or
void myclass (sometype *something = 0 );
or
// no constructor declaration at all
};

You can use static object members for it or pointer to object ....
