Double pointer difference when using with array

Question

Is there a difference between the following two lines and if so what is it? (in C++)

float (**a[10]);
float *(*a[10]);

Answer 1

No. Try

float (**a[10]);
float *(*b[10]);
if (typeid(a) == typeid(b))
    printf("==\n");
else
    printf("!=\n");

The output is

==
