Hi C++ students,

    Today we had a hands-on class in Wright 112.  Tommorrow will be
the Wright 105 classroom again and we will have a quiz on Wednesday
June 14th, instead of having it on Tuesday June 13th.

    Tommorrow there will be two goals:

     1.  Prepare you for fully understanding the programming
         assignment.

     2.  Prepare you for the quiz.  Review the while loop and the 
         hands-on C++ code that we did in the lab today.


    We basically worked on the while loop today and the classic
problem of keeping a sum and a count and obtaining the average of
a set of numbers.  

    We also introduced the sqrt() function and the <math.h> library.
The #include <math.h> statement is needed, if your program is going to
use the sqrt() function.  The output of the following statement would
be 
    12
    9
    4          cout << sqrt(144) << endl
                    << sqrt(81)  << endl
                    << sqrt(16);

    See page 111 of the textbook for a discussion of the sqrt() function
and the <math.h> library.  We will probably start chapter 3 on Tuesday,
so read section 3.1 Introduction pages 106-107 and
        section 3.2 Predefined Functions pages 107-115 to prepare for 
                                                       and to review
                                                       lectures 7 and 8.
