Binary files...again. Loading for a game.

[Zexanima]

When I try to open a binary file that doesn't exist does it create one? If not, how can I make it?

[modoran]

Like this:

#include <cstdio>
FILE *fp;
fp  = fopen("test.txt", "wb");
fclose(fp);

I don't have a programming environment infront of me, but as far as I can remember, opening a file that does not exist returns an error. Assuming you are using fstream, you can do this to create a file:

ofstream file("C:/file.txt");
file.close();

That will create a file in C: root, called file.txt. You can then use it as normal. You may want to read: http://cplusplus.com/doc/tutorial/files/

Thanks. I found out it auto-creates one if you don't have one though. The game I'm working, and it can save, but it won't load. Any idea why? This is only my second game/program, and I've only been teaching myself for a week or so, so it may seem a bit ridiculous because I'm not the best coder yet.
