#ifdef BOB

if I have
#ifdef BOB
  printf("Hello");
#endif

in a c file.  Is there any other way to get the printf statement to be compiled other than with this line code
#define BOB 10

some where in the path of compilation.

Well first of all, if you are using BOB simply as a pre-compiler tag, you do not need a value.

eg #define BOB

....would be sufficient.

As far as another way, most compilers support the -D option (or a variation) at the command line.

For example, under UNIX:

cc -DBOB myfile.c  [...other parameters]

....defines BOB for compilation (note that there is no space between "D" and "BOB")

Thanks, I didn't know about the -D option.  That was where I need to look.
