Thread: Printing a double forwardslash...?

EDIT: new question at the bottom :S

Hello again, everybody.
I am trying to write a quick-and-dirty program to format some html. I can print to the file and everything, but my problem is that html often has two successive double-forwardslashes, eg //. How can I get these to print to the file rather than being read as comment marks?

Thanks

Off the top of my head, won't "\//" work?
EDIT: Or you could just google an ascii chart and plug in the numbers instead.

What's wrong with "//"? Just a regular two forward slashes works for me... I don't think you can start comments inside string literals. This compiled and worked fine (with no errors) for me...

"\//" doesn't work, however. (Well, it will...) If you use that, you get warned as such:

Code:

slashx2.c:5:9: warning: unknown escape sequence '\/'

This compiles & works fine for me:

Code:

#include <stdio.h>

int main()
{
	printf("//");
	return 0;
}

Code:

C:\...>gcc -Wall -O2 -o slashx2.exe slashx2.c

C:\...>slashx2
//
C:\...>gcc -v
...
gcc version 3.4.2 (mingw-special)

Okay, new problem, I'm afraid....

I have tried the FAQ but the method for changing directories doesn't appear to work. What I want to do is to make a new directory with a name based on a user input.

I have aquired the filename through fgets so it could be more than one word...would this make a difference? Based on some fiddling I don't think so.. It doesn't seem to make any difference whether or not the name has spaces in.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

...

fgets(booktitle, sizeof(booktitle), stdin) != NULL;

    if ((p = strchr(booktitle, '\n')) != NULL)
             *p = '\0';      //strips trailing newline
    mkdir(booktitle);
    chdir(booktitle);

This compiles fine (all variables are declared), but the program crashes at the chdir.

cheers again...

EDIT: names of variables.

Yes, I agree that I need to check whether or not they succeed. At the moment, though, I just want them to work. I am not using UNIX, and I did consider that that could be the problem (ie, those are unix commands, are they not? I just assumed that as well as UNIX they were valid in C, the same way that functions are often named the same in different languages).

I am working in Windows XP - should I be using windows.h instead? Sorry to keep asking questions that are probably obvious. I have searched and googled and things.

Basically, all I want to do is take an input, create a directory with the name of that input, and then write a load of files to that directory.
It *should* be really simple, and I'm sure it is...

EDIT: I hadn't noticed that I had posted booktitle and fileoutname like that. I was just trying another input method, which I didn't post. Please assume that they are the same variable (i'll edit my original post too)

incidentally, "C" really is a frustrating name for a programming language. I mean, if I was using visual basic I could google "visual basic" make directory or something, but "c" is such a rubbish keyword.[/rant]
