How to Delete files

imagine i make a program that needs to store a var in a separated file ( Auxiliar_file.txt ) and when i finish it i want the program to delet it.
all i know is to erase whats inside but how i delete it ?

REASON: i want to make a game and i will need few vars ( HP,MP,Points,EXP,LVL ... ) and when the user delelets the account ( in the game imagine 1-Generate caracter; 2-Load character ... see?? ) well whe the user wants to delete its character how i delete the files i created ?????

Do you want the program to delete the actual file or delete the information in it?

:D

The easiest way would be with a call to the system; but that is not portable from OS to OS.

For windows based:

Code:

---

        system("del myfile.txt");

Yeah, yeah... some people have trouble phrasing exactly what they mean, and most people don't like getting code that deletes files that they don't actually want deleted.

Anyway, that's not the best way to do this. As we all know making that call is bad.

cstdio has a function called remove().

Code:

---

remove(filename);

---

...and this is portable. Just make sure you close the file before you attempt to remove it, otherwise this function fails.

Be warned, this DELETES the file from the computer permenantly. If that's not what you wanted, then don't try it on any important files.

Never mind, just make sure your file is in the current directory or use the full path

Sweet!
I always forget about all the cool things in the standard libraries! I be tha suck!

unlink() is also available on both MS-Windows and *nix. I think it is just another name for remove(), but *nix people like unlink() because that's how they remove files on the command-line -- I think.
