Question

What are the differences between an array of char pointers and a 2D array?

Answer 1

char* pasz[3] = {"abc", "def", "ghi"};
char asz[3][] = {"abc", "def", "ghi"};

The similarities and differences are basically the same as between these two:

char *psz = "jkl";
char sz[] = "jkl";

---

The first is originally read-only.

psz[0] = 'a'; // Illegal!!

The second, you can modify, since you allocate it with the [].

sz[0] = 'b';
// sz == "bkl"

---

The first, you can modify what it points to:

char mysz[] = "abc";
psz = mysz;

psz[0] = 'b';
// mysz == "bbc"

The second, you cannot:

sz = mysz; // Can't assign an array to an array!!
