Can you expand #define's into string literals?

Question

Is there a way to get the C++ pre processor to expand a #define'ed value into a string literal?
for example:

#define NEW_LINE '\n'
Printf("OutputNEW_LINE"); //or whatever

This looks to me like it should be possible as it's before compilation?
Or is there a better design pattern to achieve this kind of behaviour (without resorting to runtime fixes like sprintf)? Thanks

EDIT i understand that #define's can be evil, but for arguments sake...

ADDITIONAL Does anyone have any criticism of this approach?

Answer 1

If I remember correctly it is

Printf("Output" NEW_LINE);

Answer 2

This will do it:

#define NEW_LINE "\n"         // Note double quotes
Printf("Output" NEW_LINE);

(Technically it's the compiler joining the strings rather than the preprocessor, but the end result is the same.)

Answer 3

You can do the following.

#define NEW_LINE "\n"
printf("Output" NEW_LINE);

Answer 4

Well....

printf("Output%s", NEW_LINE);

Answer 5

#define NEW_LINE "\n"
printf("Output" NEW_LINE); //or whatever

should do the trick.
