checking files

what is the easiest way to check if a file already exists?

I am fairly new to C/C++, but one alternative would be to check if you can open the file or not.

Sample code:
int checkFile(char filename[]) {
FILE* fp; // file pointer
int retval; // return value

fp=fopen(filname, "r"); // open file for reading

if (fp) // check if file was opened successfully or not
retval=1;
else
retval=0;

return retval; // return 1 or 0
}

Basically, if the file already exists, then you will be able to open it. If it doesn't exist, then opening will "fail".
Hope this helps

i don't know how to use that library, is there any easy way w/ fstream?

You could always try opening the file for reading and call the fail() method to check if it failed or not.
