What is the type of the variable b in the following declaration?
#define FLOATPTR float*
FLOATPTR a,b;
a) float b) float pointer c) int d) int pointer

float * :p

float

a) float is the right answer

a)float

float

When the statement FLOATPTR a,b; is encountered, FLOATPTR is replaced by the macro expansion float * i.e the statement now becomes float * a,b;
So, b is a pointer to float.

b is a plain float.

FLOATPTR a,b; expands to float* a,b;, which is *parsed* as float (*a),b;. The * is bound to the declarator, not the type specifier, so only a is declared as a pointer to float.

b) float pointer
