21 Aug Just Whats Left Of My Assighnments For A Beginner Pseudocode Class I Currently

Chapter 8

 

Exercise

1.       Design an application that accepts 10 numbers and displays them in descending order.

 

 

4. The village of Ringwood conducted a census and created records that contain household data, including income. Ringwood has exactly 75 households. Write a program into which a village statistician can enter each of the 75 household income values, and determine the mean and median house-hold income.

 

13. Your student disk contains fi les named DEBUG08- 01. txt, DEBUG08- 02. txt, and DEBUG08- 03. txt. Each fi le starts with some comments that describe the problem. Comments are lines that begin with two slashes (//). Following the comments, each fi le contains pseudocode that has one or more bugs you must fi nd and correct.

Exercises 1,2,3,6

1. Identify three objects that might belong to each of the following classes: a. Automobile b. Novel Author c. College Course

 

2. Identify three different classes that might contain each of these objects: a. Wolfgang Amadeus Mozart b. My pet cat named Socks c. Apartment 14 at 101 Main Street

 

3. Design a class named Customer Record that holds a customer number, name, and address. Include methods to set the values for each data field and display the values for each data field. Create the class diagram and write the pseudocode that defines the class.

 

6. Complete the following tasks: a. Design a class named Book that holds a stock number, author, title, price, and number of pages for a book. Include methods to set and get the values for each data fi eld. Create the class diagram and write the pseudocode that defi nes the class. b. Design an application that declares two Book objects and sets and displays their values. c. Design an application that declares an array of 10 Books. Prompt the user for data for each of the Books, then display all the values.

 

 

 

 

Chapter 9

Exercises 2, 5, 6

 

2.       Create the logic for a program that continuously prompts the user for a number of dollars until the user enters 0. Pass each entered amount to a conversion method that displays a breakdown of the passed amount into the fewest bills; in other words, the method calculates the number of 20s, 10s, 5s, and 1s needed.

 

 

5. a. Create the logic for a program that performs arithmetic functions. Design the program to contain two numeric variables, and prompt the user for values for the variables. Pass both variables to methods named sum() and difference(). Create the logic for the methods sum() and difference(); they compute the sum of and diff erence between the values of two arguments, respectively. Each method should perform the appropriate computation and display the results. b. Add a method named product() to the program in Exercise 5a. Th e product() method should compute the result when multiplying two numbers, but not display the answer. Instead, it should return the answer to the calling program, which displays the answer.

 

6. Create the logic for a program that continuously prompts a user for a numeric value until the user enters 0. Th e application passes the value in turn to a method that squares the number and to a method that cubes the number. The program displays the results before reprompting the user. Create the two methods that square and cube a number passed to them, and then return the calculated value.
