What's with "\" ???
Author
Why does C++ not like it when I do this:
LPSTR path = "C:\";
??? I get errors like "newline in constant" and "missing ;" on the next line down. When I take out the "\" in the string, I get no errors! Why is this? I've never had this problem before. I also noticed when putting it inot a define like this:
#define PATH "C:\PFiles\C++\" // these comments aren't green!!
the comments afterwards aren't comments! anyone know what's going on here?

In C/C++, using a \ in a string indicates an escape sequence. For example:
\n - newline
\t - tab
\" - double-quotes
To get a backslash character, just use it twice in a row, like this: \\. So a valid filename would look like this:
#define PATH "c:\\pfiles\\C++\\"

The following sentence is true.
The preceding sentence is false.

\ starts a sequence ( in c/c++ ) ( like \n \r \t \" ).
If you want to use only a \ you have to write \\ ( so it looks like this
LPSTR path = "C:\\";
)
That''s all.

LPSTR path = "C:\\";
)
That''s all.
C was designed on a unix system, so you can use / instead of \\. \\ will not work if you are on a unix system only on windows. new compilers should be clever enough to make the switch, be I would not bet on it.
char* pcString[Size] = "c:/directory/file";
char* pcString[Size] = "c:/directory/file";

That has nothing to do with C, it has to do with the operating system.
even on windows, the forward slash "/" is the directory separator. the backslash is basically only used in the shell.

It's used in many more places than that, most Windows programs use \ (Explorer for example).

Backslash is used under DOS, in case you have not been using computers for long enough to have used it, and the forward slash is not a valid delineation character for DOS. And the / being used in C is to do with the language. If you try using that under DOS it will _NOT_ work. The reason the www uses / as its delineation character is because it is based on UNIX, which as mentioned before used / as its delineation character.
Please state the nature of the debugging emergency.

So to sum up, in C/C++ if you want a forward slash in a string, use /.
If you want a backslash in a string, use \\.
If you want a backslash in a string, use \\.
