Structure...

[MarkLaz]

Hello all,

Can I put a structure in a header file (as in, for use in main body of code, but to keep things tidy)?

Cheers....

It's an ambiguous question.
You may place a structure declaration, but not a structure definition.
For example:

// header example.h:
struct S { ... }; // or
typedef struct { ... } S; 
// cpp files:
#include "example.h"
S s; // Global structure variable in 1 file only
// in others:
extern S s;

You may add in the header (after S declaration):

extern S s;

then write in one of (and the only) files s var definition:

S s;

If you have in the header

struct S { ... } s;

- you have not-unique s definitions in cpp files with #include "example.h".
