Writing Pseudocode Statements With Different Variables

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

1. Suppose myCar is the name of a class variable that references an object, and go is the name of a method. (The go method does not take any arguments.) Write a pseudocode statement that uses the myCar variable to call the method.

2. In pseudocode, write the first line fo the definition for a Poodle class. The class should extend the Dog class.

Look at the following pseudocode class definitions:
Class Plant
Public Module message()
Display "I'm a plant."
End Module
Class Tree Extends Plant
Public Module message()
Display "I'm a tree."
End Module
End Class
Given these class definitions, what will the following pseudocode display?
Declare Plant p
Set p = new Tree()
Call p.message()

3. Design a class named Pet, which should have the following fields:
name - The name field holds the name of a pet
type - The type field holds the type of animal. "Dog", "Cat", and "Bird"
age - The age field holds the pet's age

The Pet class should also have he following methods:
setName
setType
setAge
getName
getType
getAge

4. Design a class and a program that creates an object of the class and prompts the user to enter the name, type, and age of his or her pet. This data should be stored in the object. Use the object's accessor method to retrieve the pet's name, type, and age and display this data on screen.

5. Design a class that holds the following personal data: name, address, age, and phone number. Write appropriate accessor and mutator methods. Also, design a program that creates three instances of the class. One instance should hold your information, and the other two should hold your friends' or family members' information.

Problem #1
Suppose myCar is the name of a class variable that references an object, and go is the name of a method. (The go method does not take any arguments.) Write a pseudocode statement that uses the myCar variable to call the method.
Solution:
Class Car
Public Module go()
// Do something
End Module
Declare Car myCar
Set myCar = new Car()
Call myCar.go()

Problem #2
In pseudocode, write the first line fo the definition for a Poodle class. The class should extend the Dog class.
Solution:
Class Poodle Extends Dog

Problem #3
Look at the following pseudocode class definitions:
Class Plant
Public Module message()
Display "I'm a plant."
End Module
Class Tree Extends Plant
Public Module message()
Display "I'm a tree."
End Module
End Class
Given these class definitions, what will the following pseudocode display?
Declare Plant p
Set p = new Tree()
Call p.message()
Solution:
I'm a tree.

Problem #4
Design a class named Pet, which should have ...

Understanding how to declare and use variables in computer science homework.

How do you figure out how to declare a variable? How do you know what type of variable to use? What is the best way to name a variable and why? What are the differences between an integer variable and a floating point variable? When and why do data type conversions occur? What is the modulus operator?

Write a short java statement for each question item

1) Declare a variable for each of the data types, pay attention to the naming convention and syntax

a. a int variable representing the number of students, the value of this variable is 45.

b. a double variable representing a student' s GPA.

c. a float variable representing the amount you need to pay for gas at a gas station.

d. a char variable that has the value of C.

e. a String variable containing the name of your pet/hometown/your favorite dish.

2) Write down the result for the following statement.

a. inta=15; float b = 15.0; ?c = a + b;?Question: the data type of c should be ___30___

b. inta=5;?double b = 15.0;?c = a + b;?Question: the value of c is ___20___, the data type of c is ___double____

c. int numOfPeople = 10;?int numOfApple = 4;?c = numOfPeople / numOfApple;?Question: the value of c is __2.5_____, the data type of c should be _______

d. int numOfPeople = 10;?int numOfApple = 4;?c = numOfPeople % numOfApple;?Question: the value of c is _______, the data type of c should be _______

e. int numOfPeople =10;?int numOfApple = 4;?double applePerPerson = 0.0;?applePerPerson = numOfPeople / numOfApple; Question: the value of applePerPerson is ______.

f. int num1 = 5; int num2 = 4; ?int result = num1 % numb2;?Question: the value of result is __________.

g. Let assume you have 1003 cents, using / and % to write a block of java statement to calculate the number of dollars, quarters, and cents you have.
Section Three

Write a block of pseudo code that captures the following federal tax bracket, please note that the following chart is an approximation of the tax bracket, but is not the actual tax bracket:

For people who file single status, Taxable income
0 - $8,500 $8500-$34,500 $34,500 - $83,600 $83,600 - $174,400 $174,400 - $379,150
$379,150 above
tax bracket 10%?15%?25%
28% 33%
35%
