Hi, I am writing a little program that reads in a file and then outputs the contents to another file but ommiting new line characters, the problem is, the code is just creating a complete copy. here is the meat of it
character = getc(inFile);
	while(character != EOF)
	{
		if(character == '/n')
			;
		else
			putc(character, outFile);
		character = getc(inFile);
	}
[/Source]
[/source] Can you see what's wrong with that?

my god, what an idiot, it's been a while lol.

Cheers.


Actually, what's ment to happen is my program takes a txt file and removes all \n from it, is there a faster way to do this than using a temp file, as at the end i delete the original file the rename the temp one.

reader.read(&data[0], data.size());
data.erase(std::remove(data.begin(), data.end(), '\n'), data.end());
reader.close();
std::ofstream writer("file.txt", std::ios::binary);
std::copy(data.begin(), data.end(), std::ostream_iterator<char>(writer));
}
