Although the compiler doesn't have a separate preprocessor, the directives described in this section are processed as if there were one. You use them to help in conditional compilation. Unlike C and C++ directives, you can't use these directives to create macros. A preprocessor directive must ...

which would result in 1 * 5 being evaluated before the addition, not after. Oops! It is also possible to write simply #define [identifier name] which defines [identifier name] without giving it a value. This can be useful in conjunction with another set of directives that allow conditional...

We have already introduced the C preprocessor directives #include and #define for file inclusion and symbol definition capabilities. In this chapter, we expand the discussion to include the #undef directive, and the use of the conditional compilation directives #if, #ifdef, #ifndef, #else and #...
