Need help with initializing an array

Ehat is the exact error? Which compiler do you use? I'm not sure at all, but try removing the '2' from the square brackets...

Original post by Adam4444 Hmm... Can't initialize my array so it compiles. Anyway it looks like this now: typedef struct Object_ { int x, y; int w, h; char *image;} Object;typedef struct Map_ { long length; int speed; Object objects[];} Map;Map game_maps[2] = { { 1000, 5, {{40, 15, 10, 10, "tux.bmp"}} }}; It's on line 19 it fails. But I don't know how it should look like. Some help would be nice. :)

You need to declare the length of array of Objects in the Map_ struct, or declare it as a pointer to Object (Object*) and make a dinamic initialization with new or malloc.

    Object objects[];

This does not - cannot - declare an array of Objects embedded within the struct, because no size is given. Instead it declares a pointer embedded within the struct, that will need to be pointed at some other region of memory (likely a dynamic allocation) where the Object instances will be stored. You just can't initialize them like that. (The reason it works for char*s is that char*s are special: the string literals can be embedded into the static segment of the executable, and the struct is initialized with a pointer value that is known at compile-time. However, equivalent syntax doesn't exist for other types.)

You should be able to initialize the Object array separately, and then initialize the Map with a pointer to that array:

Object game_objects[1] = { {40, 15, 10, 10, "tux.bmp"} };Map game_maps[1] = { { 1000, 5, game_objects } };

However, this all smells very much like you are doing things wrong. For starters, are you actually working in C, or simply carrying over a full set of bad habits to C++? Also, why not read the data from a file?

Damn, that was stupid of me. :S Thanks for the help though.
