+ Questions

+ The beautiful friendship between binary & hexadecimal

+ Play with pointers.c
    
+ The many variants of char *

    char ch; 
    char buffer[10];
    char *p1 = buffer;
    const char *p2 = p1;
    
All of these are char *'s (but with different kinds of "const")

    &ch
    buffer
    &buffer[3]
    p1
    p2

+ Dynamic allocation of memory
- malloc
- free
- ???

+ The char *'s above with const info specified
    &ch                  (char * const)
    buffer               (char * const)
    &buffer[3]           (char * const)
    p1                   (char *)
    p2                   (const char *)
                         (equivalent to: char const *)
