#define line of code to something else

Question

Is it at all possible in c/c++ to do something like to following:

#define (_asm int 3;) (exit(1))

So that everywhere in my code this line will be replaced at compile time. I know this is bad practice but is it possible.

cheers

Answer 1

You could do a global search and replace with your programming editor (or IDE) of choice and change _asm int 3 to e.g. FOO, and then define a macro FOO like this:

#if 1 // <<<- change this test to determine how `FOO` is expanded
  #define FOO _asm int 3
#else
  #define FOO exit(1)
#endif
