small code C->FB

[VANYA]

How does this translate to properly FreeBasic?

Code: Select all

struct A {

	int B;

	struct {
		unsigned char D;
		signed char F;	
	} map[100];
};

Maybe this:

Code: Select all

TYPE A1
    D AS UBYTE
    F AS BYTE
END TYPE

TYPE A
    B AS integer
    map(100) AS A1
END TYPE

led-bloon translation is OK, but It's

• map(100-1) AS A1

(This may be important if the upper bound of the array is used somewhere in the code.)

led-bloon and TJF
thanks!

Tks TJF - point taken

I suggest '0 to 100-1', to distinguish it from the C-style array format.
'0 to n-1' is a good idiom to get used to in BASIC - it's handy in array declarations and For loops.

Or that other (except if the strucure must be a single block of memory):

Code: Select all

TYPE A1
    D AS UBYTE
    F AS BYTE
END TYPE

TYPE A
    B AS integer
    map AS A1 PTR = NEW A1[100]
    DECLARE DESTRUCTOR ()
END TYPE
DESTRUCTOR A ()
    DELETE THIS.map
END DESTRUCTOR

Otherwise:

Code: Select all

TYPE A1
    D AS UBYTE
    F AS BYTE
END TYPE

TYPE A
    B AS integer
    DECLARE PROPERTY map () AS A1 PTR
  Private:
    map0(0 TO 100-1) AS A1
END TYPE
PROPERTY A.map () AS A1 PTR
    PROPERTY = @THIS.map0(0)
END PROPERTY

@fxm

If VANYA is talking about a header translation then your code wont be helpful (it wont work).

Yes, I translation the header. But thanks anyway fxm.

Please, who knows C and is able to work with MinGW, see this topic
