For the directive #define VOLUME = X * X * X, where X is also a defined constant, the preprocessor (A) replaces X with its defined value, (B) replaces VOLUME with its defined value, (C) A and B, (D)...

For the directive #define VOLUME = X * X * X, where X is also a defined constant, the

preprocessor (A) replaces X with its defined value, (B) replaces VOLUME with its defined value,

(C) A and B, (D) none of them.

If macro A uses macro B in its replacement text, then (A) A must be defined before

B, (B) B must be defined before A, (C) the sequence is irrelevant, (D) the sequence is

implementation-dependent.
