classes->conversion correct?
May 06, 2002 08:17 AM
okie i seriously dunno whether my own conversion is correct or not...i am trying to convert Mr LaMothe's struct engine to
class type engine.
this is for the header file, is a constructor necessary here?
or must i call a default constructor, coz i dun find any
data members to add into the constructors.
and i couldnt find a place to put this:
*BITMAP_FILE_PTR
which is found on the previous structure.

for: *BITMAP_FILE_PTR
do:
typedef BITMAP_FILE* BITMAP_FILE_PTR;
Your data members should be private, and the methods (Load_Bitmap_File) public. Also, your methods (L_B_F) don''t have to take a BITMAP_FILE_PTR, because it is now a class and refers to itself via the "this" pointer.. you no longer need to pass the object to load the data into.
