hmm help-

[arnis]

Ok im having trouble compiling this. Its exactly what the book has written. I know that this book is out of standard (teach yourself c++ in 21 days).

  #include <iostream>

  typedef unsigned short int USHORT;
  typedef unsigned long int ULONG;
  enum BOOL { FALSE, TRUE};
  enum CHOICE { DrawRect = 1, GetArea, 
     GetPerim, ChangeDimensions, Quit};
  // Rectangle class declaration
  class Rectangle
 {
    public:
      // constructors
      Rectangle(USHORT width, USHORT height);
      ~Rectangle();

      // accessors
      USHORT GetHeight() const { return itsHeight; }
      USHORT GetWidth() const { return itsWidth; }
      ULONG GetArea() const { return itsHeight * itsWidth; }
      ULONG GetPerim() const { return 2*itsHeight + 2*itsWidth; }
      void SetSize(USHORT newWidth, USHORT newHeight);

      // Misc. methods
      void DrawShape() const;

    private:
      USHORT itsWidth;
      USHORT itsHeight;
 };

 // Class method implementations
 void Rectangle::SetSize(USHORT newWidth, USHORT newHeight)
 {
    itsWidth = newWidth;
    itsHeight = newHeight;
 }


 Rectangle::Rectangle(USHORT width, USHORT height)
 {
    itsWidth = width;
    itsHeight = height;
 }

 Rectangle::~Rectangle() {}

 USHORT DoMenu();
 void DoDrawRect(Rectangle);
 void DoGetArea(Rectangle);
 void DoGetPerim(Rectangle);

 int main ()
 {
    // initialize a rectangle to 10,20
    Rectangle theRect(30,5);

    USHORT choice = DrawRect;
    USHORT fQuit = FALSE;

    while (!fQuit)
    {
      choice = DoMenu();
      if (choice < DrawRect || choice >  Quit)
      {
        std::cout << "\nInvalid Choice, please try again.\n\n";
        continue;
      }
      switch (choice)

        std::cin >> newLength;

        std::cout << "\nExiting...\n\n";

Are those the only includes you have?
It works fine here, too.

Some of those, though, lead me to believe you either have a windows project going, or included <windows.h> -- your program shouldn't even know the existence of HDC, a typedef for HDC__* that is windows-specific. That also might explain FALSE and TRUE errors, if they're already defined. That error seems to indicate that FALSE is a #define for 0, TRUE a #define for 1, which makes the enum evaluate to

enum BOOL { 0, 1};

which of course is illegal.

In fact, if I add #include <windows.h> I get errors at all the same places as you.

[arnis]

Yes that's the only include i have.
If i comment out the enum bool part. I get one less error.

It's not a windows project so its very strange.
Maybe windows.h is included automatic in the newest beta version of Dev c++ for some reason.

This ........es me off

Have you downloaded the Borland 5.5 C++ compiler to try against that? As it's a free download from Borlands website, it would be a good test.

[Zach L.]

Probably some option you have set somewhere. I'll play around with Dev when I get home later to see what it might be.

Might want to check in "Compiler Options" though for anything that might be linked in that seems out of place.

It works fine on Dev-C++ 4.01.
