Car Class
Write a class named Car that has the following member variables:
• year. An int that holds the car’s model year.
• make. A string object that holds the make of the car.
• speed. An int that holds the car’s current speed. In addition, the class should have the following member functions.
• Constructor. The constructor should accept the car’s year and make as arguments and assign these values to the object’s year and make member variables. The constructor should initialize the speed member variable to 0.
• Accessors. Appropriate accessor functions should be created to allow values to be retrieved from an object’s year, make, and speed member variables.
• accelerate. The accelerate function should add 5 to the speed member variable each time it is called.
• brake. The brake function should subtract 5 from the speed member variable each time it is called.

Demonstrate the class in a program that creates a Car object, and then calls the accelerate function five times. After each call to the accelerate function, get the current speed of the car and display it. Then, call the brake function five times. After each call to the brake function, get the current speed of the car and display it.

Write a Java application that prompts the user for an age. If the age entered is greater or equal to 65, display the statement "Age is greater than or equal to 65"; otherwise display the message "Age is less than 65". If the age entered is less than 18; display the statement "This person is a minor"; otherwise display the message "This person can legally vote. Do not create a class for this application. The code can be created in the main driver program.

1. What is the structure data type in C?

2. What is the value ranges of data type of unsigned char, unsigned short, respectively?

3. How many regular resisters are in this X-CPU?

4. How does the X-CPU access the memory?

5. What is the maximum memory address?

6. Which statements in the code is to increase the PC value?

7. What is the minimal cycle number that is just needed to print “Hello world!” 4 times?

8. what is the minimal cycles number do that is just needed to print ONE “Hello world!” once?

10. We are trying to assign the value of a variable named “FirstNumber” to a variable named “SecondNumber”. They are declared as shown below. Which of the following statements is correct?

double FirstNumber = 25.5;

int SecondNumber;

Group of answer choices

c. SecondNumber = int.Parse (FirstNumber);

b. SecondNumber = (double) FirstNumber;

d. SecondNumber = double.Parse (FirstNumber);

a. SecondNumber = (int)FirstNumber;

JAVA please write this method

public static void recursiveMergeSort(int[] arr) {

}

Write a C program that prompts the user to enter three sets of five double numbers each. (You may assume the user responds correctly and doesn’t enter non-numeric data.)

The program should accomplish all of the following:

a. Store the information in a 3×5 array.

b. Compute the average of each set of five values.

c. Compute the average of all the values.

d. Determine the largest value of the 15 values.

e. Report the results.

Each major task should be handled by a separate function using the traditional C approach to handling arrays.

Accomplish task “b” by using a function that computes

and returns the average of a one-dimensional array; use a loop to call this function three times.

The other tasks should take the entire array as an argument, and the functions performing tasks “c” and “d” should return the answer to the calling program.

When using for loops, please write them like this because this is the only way my compiler takes them.

int i = 0;

for( i < 6; i++)

I have to declare outside of for loop for some reason

1. What are the benefits of writing a change management policy? Why is an understanding of risk and risk management so important to an effective and successful information security program? Support your answer with material from the eText or the academic literature.

JAVA please write this method

public static void recursiveSelectionSort(int[] arr) {

}

Can you explain in details how this loop works?

int[] someNums = {90, 85, 65, 95, 75} ;

a = 1;

while(a < someNums.length) {

temp = someNums [a ];

b = a - 1 ;

while(b >= 0 && someNums[ b] >temp) {

someNums [b + 1] = someNums [ b];

--b;

}

someNums [b + 1] = temp ;

++a ; }

One of the following determines when the variable is created and destroyed and how long it will retain its value.

		linkage
		storage class
		scope
		none of the above

Case Project 13-2. Detecting Hackers in the Alexander Rocco Network

You receive a frantic call from the system administrator of the Alexander Rocco network, JW Tabacchi. He tells you he has identified several intrusion attempts from sources over the Internet. You’re not sure if the hackers have gained access to the internal network. First, based on the tools described in this chapter and some of the techniques you’ve learned in this book, write a TWO PAGE report about the things you might look for to identify an attacker or a compromised host on your network. Second, make some recommendations on how you might instrument the network with network protection systems to better detect and prevent compromises in the future.

NOTE: I WANT TWO PAGE REPORT

3. Consider the following recursive algorithm for computing the sum of the

following series: S(n) = 1/1! + 2/2! + . . . + n/n!.

ALGORITHM S (n)
//Input: A positive integer n
// Procedure: fact(n) returns the factorial of the number passed

as parameter
//Output: The sum of the series: S(n) = 1/1! + 2/2! + . . . + n/n! if n = 1 return 1
else return S(n − 1) + n/fact(n)

1. Set up and solve a recurrence relation for the number of times the algo- rithm’s basic operation is executed.

2. How does this algorithm compare with the straightforward nonrecursive algorithm for computing this sum?

Code and document the following functions using NON-RECURSIVE ITERATION only.

Test the functions by calling them from a simple interactive main() function using a menu, with different values used to select the choice of function. Overall, you should have one C program (call it Lab1.c) containing one main() function and 5 other functions, where the functions are called based on an interactive user menu. The program should contain a loop that permits users to enter a new choice of function for each loop, until exit from the loop explicitly.
