In this prelab, you will be working on some of the issues related to the first full lab assignment. Please write up or type up your solutions and hand in a paper copy at the start of class on Monday. Remember: no late prelabs allowed!
This lab will consist of a number of small programming
problems to give you a chance to become familiar with
programming in Java. There is one prelab question for each
of the programming problems.
You may recall from 150 having to draw a Pyramid out of bricks. This time you will build a pyramid out of stars. They will be symmetrical and look like:
* *** ***** ******* *********
You and your friend (the computer) will play a guessing game. One of you will pick a number between 1 and 1000. The other one will guess numbers and the other will tell them if they guessed correctly or were too high/low.
Take a look at the Wikipedia entry for Benford's Law. We are going to compute the frequency distribution of the initial digits in some data files and see if this distribution (Benford's aw) actually holds for them. As part of this, we will be drawing a simple text-based histogram chart based on the frequency of the digits.
