  1. Read Chapter 1 and Chapter 2, section 5 (2.5)
  2. Take the online quiz at http://scis.athabascau.ca/html/courses/comp200n/comp_literacy200.htm
     1. Chapter 1 doesn't have answers to some of the questions -
        I know that, so you don't have to worry about it.
     2. Ignore all the stuff above question 1.

  3. email me (bartlett@umich.edu) your score from the email account you want to receive emails from me.
  4. On paper, write a program like the one in DISPLAY 1.8, that takes 2 numbers from the user and computes and displays the sum of the numbers. Be sure to use good style!

• Lab assignment Sept. 12 (due Sept. 12 at the end of class)

  The purpose of this assignment is to show you how stupid the computer is, and how careful you have to be when writing programs.

  If you want to, you may work in a group with one or 2 others. However, each of you must hand in your own work.

  1. Pleez rite yer name on PaPer that proF bartleTT has. be4 class starts fi u get there. oN time or as sun as you Kan;

  2. Together we will enter the program on p 21 in the text, using the style required by the course.
  3. Type in the program you wrote for homework. Make sure it runs correctly and is written using the required style. On the back of your homework paper, keep track of the errors you make and the message the computer gives you.
  4. Draw a line after the last error from the previous step (or get a new piece of paper). Experiment on the program we entered in 2. Torture it and see if the compiler gives you any messages. Describe each torture and write the message the compiler gives you.
  Hand in before you leave:
  
  1. Your homework due today with the compiler error messages.
  2. Printout of your homework program you wrote that you typed in, compiled and ran.

• Sept. 14 (due Sept. 19 at the beginning of class)
  1. Read Chapter 2 and Appendix 2 (pp. 976-977)

     Be sure to use good style!
     Email me your debugged code at sbartle1@emich.edu

• Lab assignment Sept. 19 (due Sept. 19 at the end of class) The purpose of this lab is to practice using if statements to do error checking.

  You can help each other with compiler errors, but write your code yourself.

  1. Hand in your homework due today.
  2. Type in the program in DISPLAY 2.3 on page 65 of your text.
  3. Add a header comment and format the program using the class style.
  4. Add code to do error checking.
     • What error checking needs to be done?
     • What should the program do if there is an error in the input?
     • Use an if/else statement to implement your error checking.

  Hand in before you leave:
  Hardcopy of your debugged, properly styled program.

• Lab assignment Sept. 26 (due Sept. 26 at the end of class) The purpose of this lab is to practice using if statements.
  Write a program that
  1. lets the user choose one of at least 4 math operators
     (you can implement more for extra credit)
  2. and then enter 2 numbers to use the operator on.
     (the type is your design decision)
  3. Include appropriate prompts.
  4. Display the results of the math operation with appropriate explanatory text.

  You can help each other with compiler errors, but write your code yourself.

  Hand in before you leave:
  Hardcopy of your debugged, properly styled program.

• Sept. 28 (due Oct. 3 at the beginning of class)
  1. Read Chapter 3
  2. Do Programming Project 1 on page 171 and make a hardcopy of your program.
     We will have a demo of the programs the first half hour of lab on Oct. 3. Everyone will vote on the program they like best. The program that gets the most votes gets 10 extra credit points. The runner up gets 5.
     Be sure to use good style!

• Lab assignment Oct. 3 (due Oct. 3 at the end of class) There are 2 purposes for this lab.
  1. Show you that messages to the user are important by having other people use your program.
  2. Learn about for loops and get some practice using them.

  What to do in the lab:

  1. Open Visual C++ with your homework assignment and start it up.
  2. Get a piece of paper and tear it in half.
     On one half write your name and leave it on your keyboard.
     Use the other half for evaluating other people's programs.
     Write the name of the person who wrote each program and notes about the program so you will know whom to vote for. (This part will count as a quiz - you get one point for each program you try out, up to 6 points.)
  3. After 30-45 minutes (depending on how much fun everyone is having) circle the name of the person you think had the best program on your quiz sheet and hand it in to me.

  4. listen to me explain the for loop.
  5. Write a program that uses for loops to output the following:
     1 2 3 4 5 6 7 8 9

     2 4 6 8 10 12

     -10 -5 0 5 10 20

     A B C D E F G

     Z X V T R P N

     1.2 1.3 1.4 1.5 1.6

     Your Name
        YourName
           Your Name
              Your Name
     
     

• Oct. 5 (due Oct. 10 at the beginning of class)
  1. Read Chapter 3.4 and 7.1
  2. Do Programming Project 6 on page 173 and make a hardcopy of your program.
     If you don't know what complex numbers are, read this, see the C++ tutor, and/or go to the Math Tutor Lab in 221 Pray-Herrold.
     Be sure to use good style!

• Lab assignment Oct. 10 (due Oct. 10 at the end of class) The purpose of this lab is to practice using loops and switch statements.

  Write a "Chinese Horoscope" program that

  1. Contains at least one switch statement.
  2. Asks the user's name.
  3. Asks the user, by name, whose Chinese Horoscope they want to see.
  4. Asks the user, in what year that person was born.
  5. Tells the user what aninmal corresponds to that birth year.
  6. Uses the random number generator to print out one of 4 different horoscopes for that year.
  7. Let the user do it again, if they want to.
     

  The Chinese characterize each year by one of 12 animals: Rat, Ox, Tiger, Rabbit, Dragon, Snake, Horse, Sheep, Monkey, Rooster, Dog, and Pig, in this order.
  1900 was the Year of the Rat.

  To use the random number generator, you must

  1. #include <math.h>
     (This contains a lot of cool functions like sin, cos, sqrt, pow, etc.)
  2. declare a variable, with a meaningful name, of type int to hold the random number
  3. call the function
     my_really_fav_random_number = rand();
     This gives you a random number between 0 and at least 32,768.

  4. if you want a random number between 0 and 9, do this:
     my_really_fav_random_number = rand() % 10;
  5. if you want a random number between 1 and 10, do this:
     my_really_fav_random_number = rand() % 10 + 1;

  You can help each other with compiler errors, but write your code yourself.

  Hand in before you leave:
  Hardcopy of your debugged, properly styled program.

• Oct. 12 (due Oct. 17 at the beginning of class)
  1. Read Chapter 4
  2. Write a program that takes 10 numbers from the user and stores them in an array. Then, using one for loop, compute the minimum, the maximum, the sum, and the product of all the numbers, and output the results to the user. Let the user do it any number of times.
     Be sure to use good style!
     HINT: It will be easier to debug if you write it for 4 numbers and then change it to 10 to hand in.
  Hand in hardcopy of your debugged, properly styled program.

• Lab assignment Oct. 17 (due Oct. 17 at the end of class)
  The purpose of this lab is to practice writing programs that solve math problems.

     3. Area of a circle calculator.
     4. Hypotenuse of a right triangle calculator.

  2. lets the user do another one,
  3. includes appropriate prompts, including the units to use,
  4. displays the results with appropriate explanatory text and proper units,

     The person with the fewest statements in their program, not counting prompts and explanatory text, gets 10 extra points.
     HINT - using arrays will help make your code short.
     Be sure to use good style!
