Exercise 6-6. Implement a simple version of the #define processor (i.e., no arguments) suitable for use with C programs, based on the routines of this section. You may also find getch and ungetch useful. The processor reads C source line by line. When it sees #define NAME replacement it calls install from the hash table …
C preprocessor directives are instructions that run before compilation. The preprocessor reads your source file, processes every line that starts with #, and hands the result to the compiler. Understanding them well means smaller code, safer constants, conditional compilation for different platforms, and header files that include safely more than once. Object-Like Macros — #define …
