CSci 51 -- Introduction to Software Development -- Spring 2001
Lab #2
For labs meeting on Jan. 25-26, 2001
Part I. Review our computing systems and email systems
Your TA will explain these systems and you will get a chance to set your
email up with various configurations. After this lab, you will be
able to understand the current computing environment in the school as well
as the university. Hobbes, Calvin, Windows NT and Novell are some
of the systems that will be covered in the lab.
Part II. Write and Test a Program
Write a program using the Spider package and a FOR LOOP to display a diagonal
line that is twelve (12) characters long. Remember that the Spider starts
in the center of the room, and center of the room is at most ten (10) moves
in a straight line from the wall. See Section 2.2 (page 44) and Section
2.3 (page 49) of your textbook for examples.
The key to doing this program is to understand the sequence of Ada 95
statements given below.
Spider.Face (Whichway => Spider.East);
Spider.Step;
Spider.ChangeColor (NewColor => Spider.None);
Spider.TurnRight;
Spider.Step;
Spider.ChangeColor (NewColor => Spider.Green);
