4. Pointers

4.2 What's wrong with "char *p; *p = malloc(10);"?

4.3 Does *p++ increment p, or what it points to?

4.5 I want to use a char * pointer to step over some ints. Why doesn't "((int *)p)++;" work?

4.8 I have a function which accepts, and is supposed to initialize, a pointer, but the pointer in the caller remains unchanged.

4.9 Can I use a void ** pointer to pass a generic pointer to a function by reference?

4.10 I have a function which accepts a pointer to an int. How can I pass a constant like 5 to it?

4.11 Does C even have ``pass by reference''?

4.12 I've seen different methods used for calling functions via pointers.
