c - Confusion about array declaration -

-

what mean in c:

char strings[ushrt_max][50];

is creating jagged array of characters called strings?

no, above not create jagged array of strings. creates array of characters 2 dimensions, capable of storing ushrt_max c strings of 49 characters in length (the fiftieth char used '\0' terminator).

a jagged array declaration this:

char *strings[ushrt_max];

with array of pointers need allocate memory individual strings, strings differ in length 1 element other. array, on other hand, has memory allocated, places limit on length of strings, , has potential of using more memory need store shorter strings.
