QuestionPointer to member function in struct Pin
Dean Seo22-Aug-11 18:29
Dean Seo22-Aug-11 18:29 
Hi,

Since I knew The Code Project, it has been helpful a lot.
Now I think I have a small misunderstanding about pointer to member function in a struct and I need your help, which will be priceless to me.

I am simply trying to see how pointer to member function works and it seems a little tricky.

The code I am having a problem with is below.


#include <iostream>
#include <conio.h>

#define KEY_ESC     27

using std::cout;
using std::endl;

class CAccount;

struct StateMap
{
	int input;
	void (CAccount::*mfp)();
};

class CAccount
{
public:
	enum
	{
		STATE_IDLE,
		STATE_INPUT,
		STATE_WAIT_ACK
	};

public:
	StateMap	map[3];
	int			m_iState;

	CAccount();

	void OnIdle();
	void OnInput();
	void OnWaitAck();
};//class CAccount


CAccount::CAccount(){
	map[0].input = 1;
	map[0].mfp = &CAccount::OnIdle;

	map[1].input = 2;
	map[1].mfp = &CAccount::OnInput;

	map[2].input = 3;
	map[2].mfp = &CAccount::OnWaitAck;

	m_iState = STATE_IDLE;
}

void CAccount::OnIdle()
{
	cout << "OnIdle()" << endl;
}

void CAccount::OnInput()
{
	cout << "OnInput()" << endl;
}

void CAccount::OnWaitAck()
{
	cout << "OnWaitAck()" << endl;
}


int main()
{
	int         ch = 0;
	int         i;
	CAccount    account;

	while ( ch != KEY_ESC )
	{
		ch = _getch();
		i  = 0;
		while ( account.map[i].input != 0 )
		{
			if ( ch == account.map[i].input )
			{
				(account.(map[i].*mfp))(); // compile error
			}//if
			i++;
		}//while
	}//while

	return 0;
}//main()


I just don't know the right syntax for that part.
How should I change that error line to make it work?

Thanks in advance.
