1) How are each of the following evaluated?
    STATMENT:     EXPLANATION:
1a) float * aaa  // declare pointer to a float named aaa
1b) bbb = &ccc   // assign address of ccc to bbb
1d) ddd = *eee   // assign the value pointed to by eee to ddd
1e) return &fff  // return address of fff to calling function
1f) *pgg+=1;     // increment thing pointed to by pgg by one
1g) phh ++;      // increment phh by one.
                 // if phh is a pointer, moves over by size of it's data type.
1h) printf(" %p \n", &pbb); // Print address of pbb
1i) int * ffgghh(int * paa, int * pbb) // header for funtion ffgghh: 
                                       // takes 2 int pointers, 
                                       // returns 1 int pointer

2) For each of the following, write a single statement.
a. Declare the variable bbbb to point to an object of type float.

ANSWER: float * bbbb;

b. Assign the address of the variable hhhh to integer variable pnum.

ANSWER: int * pnum = &hhhh;

c. Print the value of the object pointed to by pnum.

ANSWER: printf("Value at pnum is %d\n", *pnum);

d. Increment the value of the object pointed to by pnum by 5.

ANSWER: *pnum+=5; 

e. Print the address of num using pnum.

ANSWER: printf("The address of num is %p\n", pnum);

f. Change the value of num to 33 using pnum.

ANSWER: *pnum=33;

3) Write the code for a short program that has 3 float variables, 
   pointed to by ponters.  Use the pointers to modify the values in
   the three variables.
