Saving Map Array To Disk

I was wondering if anyone could give me a little help on a simple question. I have been making an RPG with DirectX 7, and have the tile engine working perfectly. Now I have made a tile editor to create the land the easy way. All is good, with the exception that I am having trouble saving my array to disk. I used a 2D map array, and was wondering if I should use the C++ stream functions, or stick with C. Someone told me to stick with C, but that doesn't seem to sound right. Anyways, I was just wondering how it would be possible to save the full map array to disk, and have it read back in the same order? Thanks in advance.

You can use write() to output an array to a file in one go if you want. There are other ways, it's going to depend on your current code. Post a sample and someone will help you.

Sorry for the extra post, I pressed tab to set my code up and I some how exited my entry. I couldn't delete it, so I just edited it so that I didn't look quite as dumb. Sorry.

I know how to save a map array to disk, and then re-load it for use, but the problem I have is this: It is a 2D array that I have my tile map set up in. Here is what I have so far:

Code:

---

/*

int main()
{
ofstream out("test1", ios::out|ios::binary);
if(!out){
    cout << "Cannot open file.\n";
    return 1;
          }

out.write((char *)&map,sizeof map);

out.close();
}

*/

How can I use something similar to save an array but in 2D array style, like map[100][100]?

Your best bet is to do the following:

1) Create a map class
2) Make the actual map data private, and a 1D array.
3) Overload operator() to allow things like myMap(0,100)
4) Overload operators >> and << to allow easy string activities (the operators themselves should use read() and write()

It really makes a ton of sense to encapsulate a map in a class, and 2D arrays are bad to work with; there aren't a whole lot of guarantees about how your compiler handles them.
