Always use an enum instead of defines and always close the list with an additional count. This makes life simpler and helps the compiler.

Instead of defines:

 #define	TypeA	0#define	TypeB	1#define	TypeC	2#define MAX_TYPES	3// arrayint	m_nTypes[MAX_TYPES]// loopfor(int i=0; i 

Use enums with count:


 enum eTypes{	TypeA,	TypeB,	TypeC,	TypeCount	// !count!} TYPES;// use the TypeCount to specify the array-size:int	m_nTypes[TypeCount]// use the TypeCount in loops:for(int i=0; i
