Thread: Self Referencing (in a way)

Suppose in a class, I'd like to assign the address of the variable of that class type to a global variable, during construction. I don't know if this is possible, but it should, considering the address of the variable has already been assigned.

Something like:

Code:

class() {
   globalvarptr = &(self?);
}

this, not self. And since this is a pointer already, no need to take its address.

I didn't understand that. There's a variable lets say 'a', which is off this class. While 'a' is being constructed, i'd like to the ptr to reference the address of a.

Code:

class little_bunny { little_bunny * foo_foo; little_bunny() : foo_foo(this) { hoppin_thru_da_forest(); } void hoppin_thru_da_forest() { std::cout << "hoppin_thru_da_forest"; } };

Thanks, That's all I wanted.

Ok, I'm having another problem. The pointer that I'm going to reference to 'this' must be defined to be a 'class'. But that means that I'd have to put the class def infront of it. But the class includes this variable (globalvarptr), so it must be put before the class definition. How do I get out of this fix?

Here's the code I used:

Code:

#include <iostream>
using namespace std;

ape* aptr;

class ape
{
public:
	ape(){
		aptr =  this;
	}
	~ape(){}
};


int main()
{

	ape a;
	cout << &a << " " << aptr;
	return 0;
}

The complier errors are:

1>d:\visual studio 2005\projects\test\test.cpp(4) : error C2143: syntax error : missing ';' before '*'
1>d:\visual studio 2005\projects\test\test.cpp(4) : error C4430: missing type specifier - int assumed. Note: C++ does not support default-int

I use the VC++ Express.

Oh, and another doubt, is there any call to output the type of the variable. Python has something like: type(variable), which outputs the type.

worked like a charm. Thanks for your persistent help.
