  Actually, he was correct. You cant initialize a pointer to point to
something if you dont allocate memory for it. You CAN say

char* myHappy = "Hello, world!";

but that is different than:

char* myHappy;

myHappy = "Hello, World!";

You will also want to #include <string.h> so you can do a
strcpy(myHappy, "Hello, World!");

after you've allocated the space in myHappy.
