Chapter 9.1, Problem 6STE

Suppose a dynamic variable were created as follows:

char *p; p = net* char;

Assuming that the value of the pointer variable p has not changed (so it still points to the same dynamic variable), how can you destroy this new dynamic variable and return the memory it uses to the freestore so that the memory can be reused to create new dynamic variables?

Someone tries to fix the stack based buffer overflow problem as follows, is it secure now? why? Are there any other issues within the function's implementation below? Explain your reasoning.   int bof(char *str, int size) {   char *buffer = (char *) malloc(size);   strcpy(buffer, str);   return 1; }
What does it mean to have a pointer variable? What are you hoping to accomplish with it? What exactly is a dynamic array, and how does its functionality manifest itself? Where can I get more information on dynamic arrays and pointers?
