Difference between two declarations involving a pointer and an array

Question

What is the difference between int *a[3] and int (*a)[3]?

Answer 1

It seems like your asterisks are lost in the formatting...

int *a[3]

declares an array of 3 int*.

int (*a)[3]

declares a as a pointer to a vector of ints. This is really not much different from any other pointer, it just points to a somewhat more complicated type.

int foo[3];
int bar[3];
int (*vp)[3];
vp = &foo;
(*vp)[0] = 0;
