Suppose that you write a subclass of Insect named Ant. You add a new method named doSomething to the Ant class. You write a client class that instantiates an Ant object and invokes the doSomething method. Which of the following Ant declarations willnot permit this? (2 points)I. Insect a = new Ant ();II. Ant a = new Ant ();III. Ant a = new Insect ();1) I only2) II only3) III only4) I and II only5) I and III only

Answers

Answer 1

Answer:

5) I and III only

Explanation:

From the declarations listed both declarations I and III will not permit calling the doSomething() method. This is because in declaration I you are creating a superclass variable but initializing the subclass. In declaration III you are doing the opposite, which would work in Java but only if you cast the subclass to the superclass that you are initializing the variable with. Therefore, in these options the only viable one that will work without error will be II.

A _____ is a systematic and methodical evaluation of the exposure of assets to attackers, forces of nature, or any other entity that is a potential harm.

Answers

Answer:

Vulnerability assessment

Explanation:

Cyber security can be defined as preventive practice of protecting computers, software programs, electronic devices, networks, servers and data from potential theft, attack, damage, or unauthorized access by using a body of technology, frameworks, processes and network engineers.

Some examples of cyber attacks are phishing, zero-day exploits, denial of service, man in the middle, cryptojacking, malware, SQL injection, spoofing etc.

A vulnerability assessment is a systematic and methodical evaluation used by network security experts to determine the exposure of network assets such as routers, switches, computer systems, etc., to attackers, forces of nature, or any other entity that is capable of causing harm i.e potential harms. Thus, vulnerability assessment simply analyzes and evaluate the network assets of an individual or business entity in order to gather information on how exposed these assets are to hackers, potential attackers, or other entities that poses a threat.

LAB: Count multiples (EO)
Complete a program that creates an object of the Count class, takes three integers as input: low, high, and x, and then calls the countMultiples() method. The countMultiples() method then returns the number of multiples of x between low and high inclusively.
Ex: If the input is:
1 10 2
countMutiples() returns and the program output is:
5
Hint: Use the % operator to determine if a number is a multiple of x. Use a for loop to test each number between low and high.
Note: Your program must define the method:
public int countMultiples(int low, int high, int x)
Count.java
1 import java.util.Scanner;
2
3 public class Count {
4
5 public int countMultiples(int low, int high, int x) {

Analyze the following code:
// Enter an integer Scanner input = new Scanner(System.in);
int number = input.nextInt(); if (number <= 0) System.out.println(number);
1) The if statement is wrong, because it does not have the else clause;
2) System.out.println(number); must be placed inside braces;
3) If number is zero, number is displayed;
4) If number is positive, number is displayed.
5) number entered from the input cannot be negative.

Answers

Answer:

3) If number is zero, number is displayed;

Explanation:

The code snippet created is supposed to take any input number from the user (positive or negative) and print it to the console if it is less than 0. In this code the IF statement does not need an else clause and will work regardless. The System.out.println() statement does not need to be inside braces since it is a simple one line statement. Therefore, the only statement in the question that is actually true would be ...

3) If number is zero, number is displayed;

Answer:

If number is zero, number is displayed

Explanation:

Given

The above code segment

Required

What is true about the code segment

Analyzing the options, we have:

(1) Wrong statement because there is no else clause

The above statement is not a requirement for an if statement to be valid; i.e. an if statement can stand alone in a program

Hence, (1) is false

(2) The print statement must be in { }

There is only one statement (i.e. the print statement) after the if clause. Since the statement is just one, then the print statement does not have to be in {} to be valid.

Hence, (2) is false

(3) number is displayed, if input is 0

In the analysis of the program, we have: number <=0

i.e. the if statement is true for only inputs less than 0 or 0.

Hence, number will be printed and (3) is false

(4) number is displayed for positive inputs

The valid inputs have been explained in (3) above;

Hence, (4) is false.

(5) is also false

// Other parts omitted
void PrintAll() {
cout << "Name: " << lastName;
cout << ", Age: " << ageYears;
};
private:
int ageYears;

class StudentData: public PersonData {
public:
void SetID(int studentId) {
idNum = studentId;
};
int GetID() {
return idNum;
};
private:
int idNum;
};
int main() {
StudentData courseStudent;
/* Your solution goes here */
return 0;
}

Answers

Answer:

Replace /* Your solution goes here */

with the following:

courseStudent.SetName("Smith");

courseStudent.SetAge(20);

courseStudent.SetID(9999);

courseStudent.PrintAll();

cout <<courseStudent.GetID();

Explanation:

From the given code segment, we have the following methods defined under the StudentData class;

SetName -> It receives name from the main

SetAge -> It receives age from the main

SetID --> It receives ID from the main and passes it to GetID method

printID --> Prints all the required output.

So, we have:

Pass name to setName

courseStudent.SetName("Smith");

Pass age to setAge

courseStudent.SetAge(20);

Pass ID to setID

courseStudent.SetID(9999);

Print all necessary outputs

courseStudent.PrintAll();

Manually print the student ID

cout <<courseStudent.GetID();

write a loop that reads positive integers from stands input and that terinated when it reads an interger that is not positive after the loop termpinates

Answers

Loop takes only positive numbers and terminates once it encounters a negative numbers.

Answer and Explanation:

Using javascript:

Var positiveInt= window.prompt("insert positive integer");

While(positiveInt>=0){

Alert("a positive integer");

Var positiveInt= window.prompt("insert positive integer");

}

Or we use the do...while loop

Var positiveInt= window.prompt("insert positive integer");

do{

Var positiveInt= window.prompt("insert positive integer");

}

While (positiveInt>=0);

The above program in javascript checks to see if the input number is negative or positive using the while loop condition and keeps executing with each input until it gets a negative input

Write a recursive function that returns 1 if an array of size n is in sorted order and 0 otherwise. Note: If array a stores 3, 6, 7, 7, 12, then isSorted(a, 5) should return 1 . If array b stores 3, 4, 9, 8, then isSorted(b, 4) should return 0.

Answers

Answer:

The function in C++ is as follows:

int isSorted(int ar[], int n){

if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){

 return 1;}

if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){

 return 0;}

return isSorted(ar, n - 1);}

Explanation:

This defines the function

int isSorted(int ar[], int n){

This represents the base case; n = 1 or 0 will return 1 (i.e. the array is sorted)

if ([tex]n == 1[/tex] || [tex]n == 0[/tex]){

 return 1;}

This checks if the current element is less than the previous array element; If yes, the array is not sorted

if ([tex]ar[n - 1][/tex] < [tex]ar[n - 2][/tex]){

 return 0;}

This calls the function, recursively

return isSorted(ar, n - 1);

How long does it take to send a 15 MiB file from Host A to Host B over a circuit-switched network, assuming: Total link transmission rate

Answers

Answer:

The answer is "102.2 milliseconds".

Explanation:

Given:

Size of file = 15 MiB

The transmission rate of the total link= 49.7 Gbps

User = 7

Time of setup = 84.5 ms

calculation:

[tex]1\ MiB = 2^{20} = 1048576\ bytes\\\\1\ MiB = 2^{20 \times 8}= 8388608\ bits\\\\15\ MiB= 8388608 \times 15 = 125829120\ bits\\\\[/tex]

So,

Total Number of bits [tex]= 125829120 \ bits[/tex]

Now

The transmission rate of the total link= 49.7 Gbps

[tex]1\ Gbps = 1000000000\ bps\\\\49.7 \ Gbps = 49.7 \times 1000000000 =49700000000\ bps\\\\FDM \ \ network[/tex]

[tex]\text{Calculating the transmission rate for 1 time slot:}[/tex]

[tex]=\frac{ 49700000000}{7} \ bits / second\\\\= 7100000000 \ bits / second\\\\ = \frac{49700000000}{(10^{3\times 7})} \ in\ milliseconds\\\\ =7100000 \ bits / millisecond[/tex]

Now,

[tex]\text{Total time taken to transmit 15 MiB of file} = \frac{\text{Total number of bits}}{\text{Transmission rate}}[/tex]

[tex]= \frac{125829120}{7100000}\\\\= 17.72\\\\[/tex]

[tex]\text{Total time = Setup time + Transmission Time}\\\\[/tex]  

                 [tex]= 84.5+ 17.72\\\\= 102.2 \ milliseconds[/tex]

Explanation:

In C language
In a main function declare an array of 1000 ints. Fill up the array with random numbers that represent the rolls of a die.
That means values from 1 to 6. Write a loop that will count how many times each of the values appears in the array of 1000 die rolls.
Use an array of 6 elements to keep track of the counts, as opposed to 6 individual variables.
Print out how many times each value appears in the array. 1 occurs XXX times 2 occurs XXX times
Hint: If you find yourself repeating the same line of code you need to use a loop. If you declare several variables that are almost the same, maybe you need to use an array. count1, count2, count3, count4, … is wrong. Make an array and use the elements of the array as counters. Output the results using a loop with one printf statement. This gets more important when we are rolling 2 dice.

Answers

Answer:

The program in C is as follows:

#include <stdio.h>

#include <stdlib.h>

#include <time.h>

int main(){

   int dice [1000];

   int count [6]={0};

   srand(time(0));

   for (int i = 0; i < 1000; i++) {

       dice[i] = (rand() %(6)) + 1;

       count[dice[i]-1]++;

   }

   for (int i = 0; i < 6; i++) {

       printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");

       printf("\n");

   }

   return 0;

}

Explanation:

This declares an array that hold each outcome

   int dice [1000];

This declares an array that holds the count of each outcome

   int count [6]={0};

This lets the program generate different random numbers

   srand(time(0));

This loop is repeated 1000 times

   for (int i = 0; i < 1000; i++) {

This generates an outcome between 1 and 6 (inclusive)

       dice[i] = (rand() %(6)) + 1;

This counts the occurrence of each outcome

       count[dice[i]-1]++;    }

The following prints the occurrence of each outcome

   for (int i = 0; i < 6; i++) {

       printf("%d %s %d %s",(i+1)," occurs ",count[i]," times");

       printf("\n");    }
