  *pv = v + 1;   

   u = *pv + 1;   

   pu = &u;

Suppose each character occupies 1 byte of memory. If the value assigned to U is stored in (hexadecimal) address F8C and the value assigned to v is stored in address F8D, then a) What value is represented by &v? b) What value is assigned to pv? c) What value is represented by *pv? d) What value is assigned to u? e) What value is represented by &u? f) What value is assigned to pu? g) What value is represented by *pu?

2. A C program contains the following declaration. static char *color[6] = {"red", "green", "blue", "white", "black", "yellow"); a) What is the meaning of color? b) What is the meaning of (color + 2)? c) What is the value of *color? d) What is the value of * (color + 2)? e) How do color [5] and * (color + 5) differ?
