Can I use templates to add code in place?

[rempas]

Is there a way to use templates to place code in place. What I want to do is mimic the behavior of "#define" but using C++ templates. So I want to do something like the following:

#define exit_the_prog                                            \
 printf("Error: There was an error with the program");  \
 exit(2);

Is there a way to do that?

For something that simple, just use an inline function.

static inline void exit_the_prog() {
    printf("Error: There was an error with the program");
    exit(2);
}

Templates are for when you want to parametrise something generic in some way.
