A.  

B. 1

C. 2

D. 4

E. 5

3. Provide an example of how to achieve encapsulation in Java.

Question 3

Encapsulation is supported by ___________

You are contracted to complete the data system for Citywide Taxi Company. Now, the information for each taxi is expanded to include: taxi id (such as CTC0001), the driver’s name, the maker of the Car (such as Ford), the model of the car (such as Escape), the Color of the Car (such as Black), the license number (such as HXT 4578), the number of passages the car served in the entire shift (integer type, this field will be left empty for this project).

Question 4

Encapsulation is implemented by using__________ variable.

◯ private

◯ None of the above

◯ public 

◯ static

◯ class

Question 6

Question 10

Encapsulation and abstraction differ as ____________

◯ Can be used any way

◯ Hiding and Binding respectively

◯ Binding and Hiding respectively

◯ Hiding and hiding respectively

Question 15

Which of the following best defines abstraction?

◯ Hiding the implementation

◯ Showing the important data

◯ Hiding the important data

◯ Hiding the implementation and showing only the features

1:  O(N)(linear time) is better than O(1) constant time.

A. True

B. False

3:  What is the maximum number of dimensions an array in C may have?

A. Two

B. Eight

C. Twenty

D. Theoratically no limit. The only practical limits are memory size and compilers

5:  
If S is an array of 80 characters, then the value assigned to S through the statement scanf("%s",S) with input 12345 would be

A.  "12345"

B.  nothing since 12345 is an integer

C.  S is an illegal name for string

D.  %s cannot be used for reading in values of S

How do you generate a random integer if such that 30 <= i < 70

Create a function that takes in an array and its size. Return the average of the max and min of the array.

Create a function that takes in an int array and its size. Return the average of the even numbers in the array.

You are contracted to complete the data system for Citywide Taxi Company. Now, the information for each taxi is expanded to include: taxi id (such as CTC0001), the driver’s name, the maker of the Car (such as Ford), the model of the car (such as Escape), the Color of the Car (such as Black), the license number (such as HXT 4578), the number of passages the car served in the entire shift (integer type, this field will be left empty for this project). Your C++ program will (with array of class object):  

1. Define a class for the car with all members of variable mentioned above as private; (20 points)
2. Write all necessary class member functions to access those member variables (write or read); (40 points)
3. Read up to 50 records of data from the keyboard (provide a method to end the input before reaching 50 records); (10 points)
4. Save all records inputted from step 3 to a disk file called CTC.dat. (30 points)

Write a program called Lab 5 that has 3 methods and a main method:
1) Method isUserNameValid has 1 parameter of type string and the method returns a value of type
boolean. If the parameter has less than 8 characters then the method returns false, otherwise it
returns true.
2) Method compare has 3 parameters all of type int and has a String return type. This method will
return
a. “All Same” if all 3 parameters are equal,
b. “All Different” if all 3 parameters are different.
c. “Mix number(s)” two of the numbers are the same and the 3rd is different.
3) Method isValid has 1 parameter of type int and returns a boolean value; the method returns true if
the parameter is in the range 0,…,100 inclusive, otherwise the method returns false.
4) Main method. I want you to test methods isValid & isUsernameValid one time with a valid data
and another time with an invalid data. As for method compare test it 3 times so you can get the 3
different possible outcomes.
Example to test the isUserNameValid method
