enum in msvc++?

Declare result as an int and it will work.

When I tried to compile the following code in msvc++ 6 I got this error:

C:\Windows\Desktop\tutprogs\Enum.cpp(14) : error C2676: binary '++' : 'enum game_result' does not define this operator or a conversion to a type acceptable to the predefined operator

Alls Iwould like to know is how to get it sorted, ta

// Chapter 2 - Program 1
#include &lt;iostream.h&gt;

enum game_result 
{
  win, lose, tie, cancel
};

int main()
{
  game_result result;
  enum game_result omit = cancel;

  for (result = win; result &lt;= cancel; result++) 
  {
	  if (result == omit) 
		  cout &lt;&lt; "The game was cancelled\n";
	  else 
	  {
		  cout &lt;&lt; "The game was played ";
		  if (result == win)
			  cout &lt;&lt; "and we won!";
		  if (result == lose)
			  cout &lt;&lt; "and we lost.";
		  cout &lt;&lt; "\n";
	  }
  }
  return 0;
}


// Result of execution should be
//
// The game was played and we won!
// The game was played and we lost.
// The game was played
// The game was cancelled

Well, yeah, you should, because C++ doesn't consider enums to be ints, although C does. So, in the example above, you could not do normal integer arithmetic upon it. Your program would also have failed if you had tried

game_result result;
result = 1;
