How would I do this...? (file I/O)

Return a variable as 0 if a file does not exist, 1 if it does exist.

Thanks

Create a function that tries to open the file with a ifstream object (make sure you use the standard headers). Test whether the file is open with ifstream::is_open(). Return one if is_open() returns non-zero or zero if it returns zero.

Yes, and how exactly would I do that?

I know what functions are etc./ but how would I use the function you talked about?

thanks for helping
