compile error?

[firix]

Hi,
When I run the following code.it gives the error
Where is the wrong?

// a.h
#pragma once
#ifndef _A_H_
#define _A_H_
#include "b.h"


class B;

class A {
public:
	B *b;
	int i;
	A(int ii)
	{
		b = new B(56);
		i = ii;
		cout << "I AM a`S CONSTURCTOR" << endl;
	}

	void display1()const
	{
		cout << i << endl;
		b->display2();
		cout <<"cikti aldim CLASS A"<< endl;
	}

};




#endif

// b.h

#pragma once
#ifndef _B_H_
#define _B_H_



#include "a.h"
#include <iostream>

using namespace std;

class A;

class B{
public:
	A *a;
	int i;

	B(int ii)
	{
		i = ii;
		a = new A(45);
		cout << "I AM b`S CONSTURCTOR" << endl;
	}

	void display2()const
	{
		cout << i << endl;
		a->display1();
		cout <<"cikti aldim CLASS B"<< endl;
	}

};

#endif

int main()
{

	B b(23);
	A a(54);


	b.display2();
	
	return 0;		
}

You forgot to post the error message.

You can't call B constructor before it was declared ( line 16 of a.h )
This is the reason source file exist ;^)
