Answer:

C

Explanation:

Answer:

The program in Python is as follows:

char = input("Character: ")[0]

string = input("String: ")

kount = string.count(char)

print(kount,char,end="")

if kount!=1:

   print("'s")

Explanation:

This gets character input

char = input("Character: ")[0]

This gets string input

string = input("String: ")

This counts the occurrence of char in string

kount = string.count(char)

This prints the number of occurrence and the character

print(kount,char,end="")

This prints 's, if kount is other than 1

if kount!=1:

   print("'s")

Solution :

Here, we need to perform JOIN operation of the students and registration.

Use NATURAL JOIN operator [tex]\Join[/tex] and so no need to specify Join condition.

Also we need to selection operator tp select only those course whose major in "philosophy".

Finally we projection operator π to project only distinct students name who took at least three courses.

[tex]$\pi [\sigma_{\text{student's nam}e} [ \sigma(\text{three courses}) \Join \text{"Philosophy"}]]$[/tex]

Answer:

"In inner for loop" is printed twice.

Answer: C. 2

Explanation:

Code:

int main()

{

   int limit = 0;

   for  (int i =0; i>=limit; i-=2) {

       for (int j = i; j <= 1; ++j){

           cout << "In inner for loop" << endl;

       }

       cout << "In outer for loop" << endl;

   }

   return 0;

}

Output:

In inner for loop

In inner for loop

In outer for loop

The output "In inner for loop" print twice.

Thus, option (c) is correct.

In the given code example, the inner for loop has a condition j <= 1.

This condition means that the loop will execute as long as j is less than or equal to 1.

However, the initial value of j is i, and the value of i decreases by 2 in each iteration of the outer for loop.

When i = 8, the inner loop has the condition j ≤ 1.

The loop will iterate as long as j is less than or equal to 1.

So the inner loop executes twice: once when j = 8, and then when j = 9. The statement "In inner for loop" prints twice.

Therefore, the output print twice.

Thus, option (c) is correct.

Answer:

The true statements are :

A. assertEquals(student1,student2)  

C. assertSame(student1,student3)

Explanation:

AssertEquals() asserts that the objects are equal, but assertSame() asserts that the passed two objects refer to the same object or not, if found same they return true, else return false.

Methods are collections of named code segments that are executed when evoked

The assertion method that will return true for the given code is: assertEquals(student1,student2)  

The code segment is given as:

Student student1 = new Student();

Student student2 = new Student();

Student student3 = student1;

In Java, the assertEquals() method returns true if two objects have equal values.

Assume student1 and student2 have equal values, the statement assertEquals(student1,student2) will return true

keylogger.

Explanation:

A keylogger can be defined as a software program or hardware device designed for monitoring and recording the keystrokes entered by an end user through the keyboard of a computer system or mobile device.

Basically, a keylogger can be installed as a software application or plugged into the USB port of a computer system, so as to illegally keep a record of all the inputs or keys pressed on a keyboard by an end user.

In order to prevent cyber hackers from gaining access to your keystrokes, you should install an anti-malware software application such as Avira, McAfee, Avast, Bitdefender, Kaspersky, etc.

An antivirus utility is a software application or program that's used to scan, detect, remove and prevent computer viruses such as Malware, Trojan horses, keyloggers, botnets, adwares etc.

In conclusion, a bot can use a keylogger to capture keystrokes on the infected machine to retrieve sensitive information.

Answer:

There is a lack of predictability because of the high variance of response time. Additionally, SSTF may cause starvation of some requests. Starvation is possible for some requests as it favors easy to reach requests and ignores the far-away processes.

SSTF disk scheduling is not practically feasible because it makes an external call and is forced to wait for I/O to complete, thereby giving up its first-place position.

Shortest Seek Time First (SSTF) is a disc scheduling algorithm that is abbreviated as SSTF. Before moving the head away to service other requests, it selects the request that is closest to the current head location.

Because of the high variance in response time, there is a lack of predictability. Furthermore, SSTF may cause some requests to be denied. Some requests may experience starvation because the system prioritizes nearby requests and overlooks distant operations.

Therefore, because it makes an external call and is obliged to wait for I/O to complete, SSTF disc scheduling is not viable because it loses its first-place status.

Answer:

The program is as follows:

n = int(input("List elements: "))

mylist = []; myList2 = []

for i in range(n):

   num = int(input(": "))

   mylist.append(num)

for i in mylist:

   if i >= 0:

       myList2.append(i)

for i in mylist:

   if i < 0:

       myList2.append(i)

print(myList2)

Explanation:

This gets the number of list elements from the user

n = int(input("List elements: "))

This initializes two lists; one of input and the other for output

mylist = []; myList2 = []

This is repeated for every input

for i in range(n):

Get input from the user

   num = int(input(": "))

Append input to list

   mylist.append(num)

This iterates through the input lists

for i in mylist:

If list element is non-negative

   if i >= 0:

Append element to the output list

       myList2.append(i)

This iterates through the input lists, again

for i in mylist:

If list element is negative

   if i < 0:

Append element to the output list

       myList2.append(i)

Print output list

print(myList2)

Explanation:

Queues can be implemented using linear arrays; such that when items are added or removed from the queue, the queue repositions its front and rear elements.

The value of the REAR after adding 3 elements is 5

Given that:

[tex]REAR = 5[/tex] --- the rear value

[tex]n = 20[/tex] --- size of array

[tex]Elements = 3[/tex] --- number of elements to be added

When 3 elements are added, the position of the REAR element will move 3 elements backward.

However, the value of the REAR element will remain unchanged because the new elements that are added will only change the positioning of the REAR element and not the value of the REAR element.

Answer:

Explanation:

The following pseudocode for this method using operations of the ADT list would be the following

swap(aList, indexI, indexJ) {

    initialize temp_variable = Retrieve(indexI, aList)

    Insert(Retrieve(indexJ, aList), indexI, aList)

    Insert(Retrieve(indexI, aList), temp_variable, aList)

}

This code basically saves the aList index of i , into a temporary Variable. Then it sets the aList index of i to the value of the element in index of j. Then it does the same for the index of j with the tem_variable. If we assume that the indexes of i and j exist, then it can crash our entire program if those indexes are missing from the list when we try to access them.
