Elements of High-Quality Programs (Lesson 2: Chapter 2)

Demonstrate proper use of assigning variables.

Which of the following statements are valid assignments if productCost and productPrice are numeric variables, and productName is a string variable?

If a statement is not valid, provide an explanation why it is not.

a. productCost = 100

[Insert the answer here]

b. productPrice = productCost

[Insert the answer here]

c. productPrice = productName

[Insert the answer here]

d. productPrice = 24.95

[Insert the answer here]

e. 15.67 = productCost

[Insert the answer here]

f. productCost = $1,345.52

[Insert the answer here]

g. productCost = productPrice 10

[Insert the answer here]

h. productName = mouse pad

[Insert the answer here]

i. productCost + 20 = productPrice

[Insert the answer here]

j. productName = 3-inch nails

[Insert the answer here]

k. productName = 43

[Insert the answer here]

l. productName = 44

[Insert the answer here]

m. 99 = productName

[Insert the answer here]

n. productName= brush

[Insert the answer here]

o. battery = productName

[Insert the answer here]

p. productPrice = productPrice

[Insert the answer here]

q. productName = productCost

Making Decisions (Lesson 4: Chapter 4)

Assume that the following variables contain the values shown:

numberBig = 300 numberMedium = 100 numberSmall = 5

wordBig = Elephant wordMedium = Horse wordSmall = Bug

For each of the following Boolean expressions, decide whether the statement is true, false, or illegal.

a. numberBig = numberSmall

[Insert the answer here]

b. numberBig > numberSmall

[Insert the answer here]

c. numberMedium

[Insert the answer here]

d. numberBig = wordBig

[Insert the answer here]

e. numberBig = Big

[Insert the answer here]

f. wordMedium = Medium

[Insert the answer here]

g. wordBig = Elephant

[Insert the answer here]

h. numberMedium

[Insert the answer here]

i. numberBig >= 200

[Insert the answer here]

j. numberBig >= numberMedium + numberSmall

[Insert the answer here]

k. numberBig > numberMedium AND numberBig

[Insert the answer here]

l. numberBig = 100 OR numberBig > numberSmall

[Insert the answer here]

m. numberBig 10

[Insert the answer here]

n. numberBig = 30 AND numberMedium = 100 OR numberSmall = 100

[Insert the answer here]

Looping (Lessons 5 and 6: Chapter 5)

Programming Exercise

Based on Lesson 6 Programming Exercise B, design logic using pseudocode that modifies the movie-rating program so that a user gets three tries to enter a valid rating. After three incorrect entries, the program issues an appropriate message and continues with a new user.

Arrays (Lessons 7 and 8: Chapter 6)

Programming Exercise

The Downdog Yoga Studio offers five types of classes, as shown in the table below. Design a program using pseudocode that accepts a number representing a class, and then displays the class name.

Class Number	Class Name
1	Yoga 1
2	Yoga 2
3	Childrens Yoga
4	Prenatal Yoga
5	Senior Yoga

File Handling and Applications (Lessons 9 and 10: Chapter 7)

Programming Exercise

Laramie Park District has files of participants in its summer and winter programs this year. Each file is in participant ID number order and contains additional fields for first name, last name, age, and class taken (for example, Beginning Swimming).

Design the logic for a program, using pseudocode, that merges the files for summer and winter programs to create a list of the first and last names of all participants for the year in ID number order.

Look at the LaramieParkDistrictSummer.txt and LaramieParkDistrictWinter.txt files from your downloadable Sample Data Files to develop your solution.
