problem in compiling the c++ code

[ravinder]

#include <iostream.h>

/* This class captures all the events as virtual functions. This class
is a base class, and not one of the actual states of the FSM. */
class TurnStyleState
{
public:
virtual void Coin(TurnStyleC ontextFSM *) {};
virtual void Pass(TurnStyleC ontextFSM *) {};
};

class LockedTurnStyle State : public TurnStyleState
{
public:
virtual void Coin(TurnStyleC ontextFSM* c)
{c->SetState(TurnS tyleContextFSM: :unLocked); c->Unlock();}

virtual void Pass(TurnStyleC ontextFSM* c)
{c->Alarm();}
};

class UnlockedTurnSty leState : public TurnStyleState
{
public:
virtual void Coin(TurnStyleC ontextFSM* c)
{c->ThankYou();}

virtual void Pass(TurnStyleC ontextFSM* c)
{c->SetState(TurnS tyleContextFSM: :Locked); c->Lock();}
};

class TurnStyleContex t
{
public:
void Lock();
void Unlock();
void Alarm();
void ThankYou();
};

class TurnStyleContex tFSM : public TurnStyleContex t
{
private:
TurnStyleState* itsState;
public:
static UnlockedTurnSty leState Unlocked;
static LockedTurnStyle State Locked;
void Coin() {itsState.Coin( this);}
void Pass() {itsState.Pass( this);}

TurnStyleState* GetState() {return itsState;}
void SetState(TurnSt yleState* s) {itsState = s;}

};

void main()
{
TurnStyleContex tFSM fsm;
fsm.SetState(Tu rnStyleContextF SM::Locked);
fsm.Lock();

for(;;)
{
fsm.Coin();
fsm.Pass;
}
}

I am compiling the above code in VC++ windows environment, i am getting the compilation errors like:
error C2061: syntax error : identifier 'TurnStyleConte xtFSM'

You have to forward declare TurnStyleContex tFSM.

And use a standard iostream header without the .h, because then comes the
string inclusion without the .h and the wondering while prestandard
iostreams and standard string does not owrk together. :-(

At this point of compilation the class TurnStyleContex tFSM has not yet been
defined. However, you can resolve this problem by forward declaring it.

Even if you forward declared TurnStyleContex tFSM and made minor
corrections to the code (<iostream.h> to <iostream>, void main() to
int main(), Pass to Pass(),etc) it is still very unlikely that the
code will compile. Have you tried it?
