I have the following codes:

const int N=3;
static double * p[N];

Does p stands for a static pointer pointing to a N-dimensional double array, or a N-dimensional array with each elements standing for a static pointer?

Also I found the following change failed compilation, and not sure why…

int N=3;

    Does p stands for a static pointer pointing to a N-dimensional double array, or a N-dimensional array with each elements standing for a static pointer?

    Almost the second choice a N-sized array with each elements standing for a static pointer. Note the change from “N-dimensional” to “N-sized”. Thanks @David.

    Also I found the following change failed compilation, and not sure why…

    Arrays need constant integers for their size. After you remove the “constness” of N the size of p is uncertain at compile time.
