Switch's in C string line.

[zcoder]

I am using VC6++ and have 4 warnings that bug me
I have searched everywhere I CAN think of but can't find
why I get this warning from this :
          lstrcat((LPSTR)&szDirPath,"\Release"); /* warning C4129: 'R' : unrecognized character escape sequence */

I want the backspash to be copied and it does but it warns me couse it's also some escape sequence.
how do I get rid of the warning?

lstrcat((LPSTR)&szDirPath,"\\Release") - it will do the same job without the warning.

To extend on what shaka_zulu said, C has something called escape characters. All escape characters start with a '\' and are followed by one or more characters which are translated by the C/C++ preprocessor. A few examples are \n which translates into a line feed (ASCII character 0x0D), \r which translates into a carriage return (ASCII character 0x0A), \x which is followed by a hex value to create an inline hex character (ie. "\x0A" is the same as "\n" and, in MASM, 0Ah). In your code you used \R which there is no such escape sequence. Btw, escape sequences are case sensitive so \R and \r are not the same thing.

thanks both of you shaka_zulu, Synfire
that fixed my warnings, I knew about the \n, \r, as those are used in php also.
I did not know about \x so that will come handy.

Thanks shaka_zulu, Synfire

Personally, i love the "\a" sequence - "Ring the Bell :)" ,because it's really nice sometimes for fast debugging purposes.
