Thread: Finding out how many files are in a directory

Code:

first off, im lazy so im not gonig to turn this into C++, ill leave it in C, so you can learn something.
Second if you are new to C++, you really should AVOID this. This uses topics you are most likely unfamiliar with, and will have enormous problems trying to implement this, but have fun anyway.

one way to do it is to use a system call to help you write the directory of a drive out to a file

system("dir c: > file.txt");

then you would read in the file

std::ifstream;

then you would go through the file, using some token as something to trip a counter...

of course you'd have to read more about this, and at two days your going to need somebody to write it for you if you need it fast... but look up:

getline() (iostream)
system calls (cstdlib)
ifstream (fstream)
strings (string)

Read here ( C examples, but the concept is the same for C++) : http://faq.cprogramming.com/cgi-bin/...&id=1044780608

But as already implied, if you're new to C++, try to learn the language before learning OS specific calls.
