Array of pointers vs Multidimensional Array

Question

What the benefits and disadvantage of using an array of pointers vs a multidimensional array and vica verse in C or C++. They both seem the same to me. For example, take the following

char *people[] = {"Alex", "Tom", "Peter"};

Versus

char people[][9] = {"Alex", "Tom", "Peter"};

"visa verse" is the 4-line part of a banker's poem about credit cards. The word you're looking for is "vice versa". — The Paramagnetic Croissant, Apr 21 '14 at 04:39

multidimensional arrays are easier to work with, whereas pointer arrays sometimes result in a faster program.

multidimensional arrays cant be modified, pointer arrays can simply be changed to point elsewhere anytime.

POINTER ARRAYS: MULTIDIMENSIONAL ARRAYS multi-d arrays

Not to mention those unused memory space, such a waste.
