Complete the calcAverage() method that has an integer array parameter and returns the average value of the elements in the array as a double.(Java program)
Ex: If the input array is:
1 2 3 4 5
then the returned average will be:
3.0
Answers
Answer:
Explanation:
The following Java program has the method calcAverage(). It creates a sum variable which holds the sum of all the values in the array and the count variable which holds the number of elements in the array. Then it uses a For Each loop to loop through the array and go adding each element to the sum variable. Finally it calculates the average by dividing the sum by the variable count and returns the average to the user. A test case has been created in the main method using the example in the question. The output can be seen in the image attached below.
class Brainly {
public static void main(String[] args) {
int[] myArr = {1, 2, 3, 4, 5};
System.out.println(calcAverage(myArr));
}
public static double calcAverage(int[] myArr) {
double sum = 0;
double count = myArr.length;
for (int x: myArr) {
sum += x;
}
double average = sum / count;
return average;
}
}

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);
}

provides an automated method for discovering host systems on a network. Although it doesn't necessarily discover all weaknesses, it does determine which systems are active on the network and what services they offer or what ports are available
Answers
Answer:
Network scan
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.
Generally, a security assessment is carried out by network security experts on a regular basis to determine potential loopholes or vulnerabilities in the information and technology (IT) infrastructure. One of the techniques or approach used in security assessment is a network scan.
A network scan is a security assessment technique used for the automatic detection of host systems on a network. Although a network scan isn't capable of discovering or detecting all the weaknesses on a network, it avails users information about the computer systems that are active on the network and what services the computer systems offer or what ports are available on them.

ii. How do the first three security concepts relate to these four attacks
Answers
Answer and Explanation:
I and II answered
Interruption: interruption occurs when network is tampered with or communication between systems in a network is obstructed for illegitimate purposes.
Interception: interception occurs when data sent between systems is intercepted such that the message sent to another system is seen by an unauthorized user before it reaches destination. Interception violates confidentiality of a message.
Modification: modification occurs when data sent from a system to another system on the network is altered by an authorized user before it reaches it's destination. Modification attacks violate integrity, confidentiality and authenticity of a message.
Fabrication: fabrication occurs when an unauthorized user poses as a valid user and sends a fake message to a system in the network. Fabrication violates confidentiality, integrity and authenticity.

The statement that is true about network protocols is that:
Using a protocol other than TCP/IP can result in data loss.What are network protocols?A network protocol is a system of principles that governs how data is delivered between devices on the same network.
Primarily, it enables linked devices to interact with one another despite variations in internal operations, architecture, or design.
The way this is done is true the use of Transmission-control protocol/Internet protocol (TCP/IP).
TCP/IP is the primary protocol or communication language of the Internet. Therefore, using a protocol other than TCP/IP can result in data loss.

Draw a Card. Write a program to simulate drawing a card. Your program will randomly select one card from a deck of 52 playing cards. Your program should display the rank (Ace, 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King) and suit (Clubs, Diamonds, Hearts, Spades) of the card. Here is a sample run of the program: in The card you picked is Jack of Heart The program should use at a minimum: sequence, selection, arrays, and random numbers.

Answer:
Explanation:
The following code is written in Java. It is a function that creates a Random object to generate random values, then uses those values to choose a random rank and suit using switch statements. It then saves the rank and suit into a String variable in the correct format and finally prints the card that was picked to the screen. The function was called 4 times in the main method and the output can be seen in the attached image below.

Random rand = new Random();
int rank = rand.nextInt(14)+1;
int suit = rand.nextInt(4)+1;
String chosenCard = "";
switch (rank) {
case 1: chosenCard += "Ace"; break;
case 2: chosenCard += "1"; break;

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:

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.

Can anyone decipher these? There a bit random. Maybe binary but if there are other ways please include them.
Answers
Answer:
Explanation:
so this is what "format" is about, it's saying what do the ones and zeros represent. b/c the bits can represent lots of different things , like letters with ascii code , and that's got several types. some are 8 bits, some are 16 bits, the questions you've shown are in groups of 5 which is really not a "thing" in binary, it's always by twos, without some type of "frame work" around the bits, we won't know what they represent, if that is helping? the important part is what is the "frame work" that these bits are in.
all of your questions seem to have some "art" thing going on, they make some kinda of binary artwork, for what they are saying, that's not what's important. Other than if they form palindromes, maybe that's what the questions are really about, how these do from palindromes, that is, they read the same backwards as forwards... I know.. why would anyone read backwards.. but a computer can do that pretty quickly, sooo sometimes to check, it will read forwards and backwards.. but when there is a palindrome, the computer is "confused"
this is also a big big part of "typing" not like on a keyboard but when you program, and you say that your variables are of a certain type, like a char, or a string, or a double, you are specifying how many bits will be used to represent your data. so then when you put the ones and zeros into the memory , ( think RAM) then it's stored in groups of what ever size you've determined. hmmmm does this help?

In Chernoff faces, each attribute is associated with a specific feature of a face (nose, eyes, ears, hair, mouth, and eyebrows), and the attribute value with respect to size, shape, orientation, colour and placement is used to determine the way a facial feature is expressed.
The Chernoff face is a technique designed and developed to help detect similarities between different items and discern subtle changes in facial expressions from the perspective of an observer.
