CSC 230: The Week beginning Oct. 7

Homework:

1. Factorial
Write a program that uses a loop to calculate a factorial of a number from a drop-down select. It should also display the way the calculation was done. See example in figure below.

2. Multiplying like rabbits. Make a page like that below that adds an image element to a page using a timer. Mine added a picture of a rabbit every half second.

Due: Oct. 16
Monday:

Simulates the roll of a die (includes a timer effect) RollDice.html
Tuesday:

Pi series

Have the user enter the number of terms they would like summed in the series for Pi. You may want to check out the Math.pow method http://www.w3schools.com/jsref/jsref_pow.asp

Die Frequencies

Make a page like that shown above. It allows the user to enter the number of times the simulated die will be rolled. It should check that the input is a number and that it is greater than or equal to one. It should set up a loop to simulate the roll of a die the number of times the user specified. Make six variables -- the first to keep track of the number of times a 1 was rolled, the second to keep track of the number of times a 2 is rolled, etc. (I used a switch structure.) After the loop the program should display the variable values. It should also display the percentages -- the percentage of 1's is the number of times a 1 was rolled divided by the total number of rolls times 100.

Due: Oct. 16
Wednesday

SnakeEyes.html uses a while loop to simulate rolling the two dice while one has not rolled two 1's. That while loop was then placed inside a for loop (nesting) to determine an average.
Friday:

HorseRace_Timer2.htm

PayOffLoan.html Not finished we have to avoid getting into an infinite loop. We also have to display our results.
