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 Program to demonstrate the Preprocessor directives like #if, #else, #define, #endif. C Preprocessors are not the program statements, they are executed before the actual compilation of the code. C Preprocessors substitute the code where they called, i.e they replace the code as they defined. #if, #else are the conditional directives. Here at the compile …
C Program to demonstrate #define pre-processor. Macro is a piece of text that is expanded by the pre-processor part of the compiler. This is used in to expand text before compiling. Macro definitions (#define), and conditional inclusion (#if). In many C implementations, it is a separate program invoked by the compiler as the first part …
