This is not at all the same as defining`TABLESIZE'to be`1020'. The`#define'for`TABLESIZE'uses exactly the body you specify--in this case,`BUFSIZE'---and does not check to see whether it too is the name of a macro. It's only when youuse`TABLESIZE'that the result of its expansi...
I am trying to write a program where the names of some functions are dependent on the value of a certain macro variable with a macro like this: #define VARIABLE 3 #define NAME(fun) fun ## _ ## VARIABLE int NAME(some_function)(int a); Unfortunately, the macro NAME...
to __STDC_VERSION__, in that it expands to a version number. A fully conforming implementation of the 1998 C++ standard will define this macro to 199711L. The GNU C++ compiler is not yet fully conforming, so it uses 1 instead. We hope to complete our implementation in the near future....
Variables which are defined const must be initialized, since they may not be assigned to. The compiler will enforce the meaning of the constant modifier. This is different than a #define macro "constant", since the const variable is a real variable, with space allocated for it by the compil...

The Lexer keeps track of an MultipleIncludeOpt object, which is used to detect whether the buffer uses the standard “#ifndef XX /#define XX” idiom to prevent multiple inclusion. If a buffer does, subsequent includes can be ignored if the “XX” macro is defined. The TokenLexer class The...
