INF1030: Introduction to Information Technology - Homework Assignments

• MIDTERM - W. Nov 23

  Covers the following:

  • Binary and Decimal (see presentation on yrosenthal.com)
  • VB.Net book - Chapters 1-4 (not including static variables - page 114 and the format function - page 146)
  • Readings from Computer Concepts book - see pages in HW2

  Two sections on exam:

  • 1st section is open book and notes but you MAY NOT use the computer. This will cover binary, info from readings, and general VB.Net questions. I might show you some code and ask you what it does.
  • 2nd section is open book and notes and YOU MAY USE THE COMPUTER. On this section you will be asked to create a VB.Net program

  ANSWERS

  • Fibonacci Program: Click here to see a solution for the Fibonacci program from the midterm. To run the program, create a new VB.Net project. Then remove ALL of the code from Form1.vb and replace it with the code in this file. Note: you must also remove the "hidden" code which is collapsed under the + sign. You can do this simply by choosing the Edit|SelectAll menu choice and then pressing the Delete button. Also note that in the solution, the lines that start with #Region " Windows Form Designer generated code " and end with #End Region contain the code for the format of the display. These lines are usually hidden in the VB.Net editor under a + sign. When you paste the code into the editor, you can hide these lines by clicking on the minus sign ( - ).
  • Another Fibonacci Program: Click here to see a slightly different Fibonacci program which adds a counter so you can what number you are up to in the sequence (you did not have to do this for the test).

• HW9 - Boolean Variables and IIF

• HW8 - Modulus and integer division - Making change
  

  Write a program that asks the user for a monetary amount in cents. The program should compute the minimum number of dollars, quarters, dimes, nickels and pennies it would take to add up to the amount the user specified.

  For example, if the user specified 289 cents, the program should report that 289 cents is equivalent to 2 dollars, 3 quarters, 1 dime, 0 nickels and 4 pennies.

  Hint: use Integer division (i.e. the backslash, "\") and the "MOD" operators.

• HW7 - Variable Scope
  Due: M Nov 7, 2005

  Assignment: Do Project 3 in section 3.8 on pages 116-122 in the VB book. Also do programming problem 4 on pages 125-126 (do not do the part for "variable X").

• HW6 - multiple forms
  Due: W Nov. 2, 2005

  Assignment: Do Project 2 in section 3.5 on pages 100-105 in the VB book. Also do exercise 3.18 on page 105.

• HW5 - VB application - word processor
  Due:

  Assignment: Do Project 1 in section 2.9 on pages 61-65 in the VB book.

• HW4 - VB application - playing with buttons
  Due:

  Assignment: Write a VB application that has two buttons. When you click on the first button, the text that is displayed on the 2nd button should change. After you click the first button once, there should be no change when you click it again.

• HW3 - algorithm
  Due: before next class (M Sept. 19, 2005)

  Assignment: Given that there are 12 stones, 11 of equal weight, 1 of unequal weight (either heavier or lighter).

  (1) Write an algorithm that describes a series of steps that you can use to find the stone that is a different weight and tell whether it is heavier or lighter. A step is one of the following (a) put a stone on the left side of the scale (b) remove a stone from the left (c) put a sone on the right (d) remove a stone from the right (e) write down some results.

  (2) Write another algorithm that uses only 3 weighings on a balance scale to tell what stone has a different weight and if it is heavier or lighter.

• HW2 - Converting decimal, binary, hex
