Application Security Testing: An Integral Part of DevOps


Use enum Terminated with count


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

// array
int	m_nTypes[MAX_TYPES]

// loop
for(int i=0; i <MAX_TYPES;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 <TypeCount;i++)
