CS010 Practice 4

C Memory Management

1. Do Exercise 14 from Chapter 13 of King again. This time use pointers, malloc and free to allocate memory for your strings instead of using arrays with a static size. Compare these two versions. Which do you like better and why?
   
2. Do exercise 5 from Chapter 17 of King.
   
3. What does the following code do. Reason it through and then execute it and see what happens. Do you understand what happens?
   

   #include <stdio.h>
   #include <stdlib.h>
      
   int main () {
     char *s1;
     char *s2;
      
     s1 = (char *) malloc (1);
     strcpy (s1, " Williams beats Wesleyan");
      
     s2 = (char *) malloc (1);
     strcpy (s2, "Amherst");
      
     printf ("%s\n", s1);
     exit (0);
   }
