What is the proper way of defining constants?



1)#define fag 0

2)const int fag = 0;

Both.

[code]
#define const int #define
const fag 0

UnFortunately some compilers don't allow redefining #define/#include
I've found out that gcc doesn't like
#define d #define
and i have to type extra chars in void.h and similar headers(usually i have append a huge chunk of empty #define's if there is need)

if defined macro definitions could expand to other definitions of macro definitions, would that make the c preprocessor touring complete?

Only in compilers which support this, like DMC

But why care about typing the extra few characters? I simply hit ^N like a baws using autocompletion.

Your powers of observation continue to serve you well.

You don't have to use autocomplete if you just use one character for #define
auto-complete is not supported in notepad2, and i don't really need it as i prefer using #define's and typing shorter strings.
3-4 chars max should be ideal, but i don't mind typing a few extra.

const int have some disadvantages. First, you'll have to move the definition to a separate translation unit (if the constant is declared in a header file). Second, you can't use it in case labels.

The best way to group a set of related constants together is through an enum. If you want to declare a single constant, though, I'd go with a #define.

The fag constant already provided by lisp interpreter, that code is superfluous.

If you type fag into any Lisp interpreter it replies with ``oh, be nice !''
