What is the output of the following code? var x = ["a", "b", "c"]; x.push("d", "e"); x.pop(); x.pop(); a. x = ["a", "b", "d", "e"] b. x = ["d", "e"] c. x = ["a", "b", "c"] d. x = ["c", "d", "e"]
Answer:
The answer to this question is option "C".
Explanation:
The stack is part of the data structure. In this stack perform two operations that are "push and pop". The push function is used to push(insert) and pop function is used to pop(delete) elements on the stack. It follows the LIFO process that stands for last in first out.
In this code, firstly we insert three elements on the stack that is "a, b and c". Then, we insert two elements on the stack that is "d and e", in this element store in the upper part of the stack and then we call pop function two times. In first time, the call will remove elements e and the second time it will remove element d.That's why the answer is option "C".

Given the following method definitions: void mystery(double a) { System.out.print("double! "); } void mystery(int a) { System.out.print("int! "); } What will be the output of the following code? mystery(1); mystery(1.0); Select one:
a. It is impossible to predict
b. int! double!
c. Duplicate function names results in a compiler error.
d. double! int!
Answer:
The correct answer to the following question is option "b".
Explanation:
The method having the same name but the arguments have different so it is called method overloading. It is a part of the object-oriented programming language (oops).
In the given code we define same method two times that is "mystery()". but in this method, we pass two different parameters. For the first time, we pass a double variable that is "a" as a parameter. In the second time, we pass an integer variable that is "a" as a parameter and in both functions, we write some codes. In the calling time, we call function two times. In first time calling we pass an integer value that is "1" and second time calling we pass double value that is "1.0". So the output of this code is "int! double!".That's why the option "b" is correct.

The rest is made of oxygen. You are asked to determine the mass of oxygen in the sample. Which of the following expressions demonstrates a mathematical procedure to solve this problem using the proper order of operations?
((100 - 35)/100) x 5.5 grams =
100 - 35/100 x 5.5 grams =
100 - (35/100) x 5.5 grams =
Recall that to calculate a percent of an amount in grams means you have to convert the percent to a number and multiply by the amount in grams. For example, 50% means 50 out of 100, or 50 hundredths. So 50% of 10 grams is 0.50 times 10 grams. You need to take 0.50 and multiply it by 10 grams to determine 50% of 10 grams is 5.0. (50% and 10 grams are examples and not numbers for this problem.)
Answer:
((100-35)/100) x 5.5grams=3.575grams of oxygen
Explanation:
Since ha sample contains 35% carbon which means (100-35)=65% is oxygen in the sample. In order to calculate the mass of oxygen in the sample we have to find the 65% of 5.5g which means we have to multiply 65/100=0.65 with 5.5g i.e 0.65*5.5. so the mathematical expression we use will be:
((100-35)/100) x 5.5grams=3.575grams of oxygen
Given this method comment, fill in the blank in the method implementation. /* Deposits money into the bank account amount: the amount to deposit */ public _____ deposit(double amount) { balance = balance + amount; }
Answer:
"void" is the correct answer for the given question.

Explanation:
There are two type of RAID
Software RAIDHardware RAIDSoftware RAID
deliver services form the host.
Hardware RAID
provides hardware services.
RAID has levels
0, 1, 5, 6, and 10
RAID 0, 1, and 5 work on both HDD and SSD media,
4 and 6 also work on both media.
RAID 0 :Striping
In this level minimum of two disks,RAID 0 split the file strip the data.Multiple hard drive are used to split the data.
RAID 1 : Mirroring
In this level Minimum two disk require and provide data tendency.
RAID 5 :Stripping with parity
Parity is a binary data.RAID system calculate the value which system used to recover the data.
Most RAID system with parity function store parity blocks.
RAID 5 combines the performance of RAID 0 with redundancy of RAID 1.
RAID 5 level should minimize the fault tolerance.
Given a char variable c that has already been declared, write some code that repeatedly reads a value from standard input into c until at last a 'Y' or 'y' or 'N' or 'n' has been entered.
Answer:
The code to this question as follows:
Code:
do{ //do-while loop
cin >> c; //input value from user.
}while (!(c == 'Y' || c == 'y' || c=='N' || c == 'n')); //check condition.
Explanation:
The description of the code as follows:
In this code, we use a do-while loop. It is an exit control loop. In the loop, we use the char variable that is "c" this variable is used for user input. End of the loop we define the condition that is variable c value is not equal to "y", "Y", "n" and "N". In the loop, we use OR operator that means if any of the above conditions is match it will terminate the loop.
Final answer:
A while loop can be used to repeatedly read a char variable from standard input until 'Y', 'y', 'N', or 'n' is entered, utilizing a do-while loop to check the condition after each input.
Explanation:
To repeatedly read a value into a char variable c until 'Y', 'y', 'N', or 'n' is entered, one could use a while loop in the following way:
#include
using namespace std;
do {
cin >> c;
} while (c != 'Y' && c != 'y' && c != 'N' && c != 'n');
This code snippet uses a do-while loop to ensure that the body is executed at least once before checking the condition. If the character entered is not 'Y', 'y', 'N', or 'n', it repeats the prompt, continuing to read the next standard input into variable c. When one of these specific characters is entered, the loop terminates.

On a compromised computer, you have found that a user without administrative privileges was able to perform a task limited to only administrative accounts. What type of exploit has occurred?
a. privilege escalation
b. DNS cache poisoning
c. man-in-the-middle
d. ARP poisoning
Answer:
a. privilege escalation
Explanation:
Privilege escalation is the act of exploiting a bug, design flaw or configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user.
Thus, if a user without administrative privileges was able to perform a task limited to only administrative accounts, this can be called as privilege escalation.
DNS cache poisoning is a type of attack that exploits vulnerabilities in the domain name system (DNS) to divert Internet traffic away from legitimate servers and towards fake ones.
A man-in-the-middle attack is an attack where the attacker secretly relays and possibly alters the communications between two parties who believe that they are directly communicating with each other.
ARP poisoning is a technique by which an attacker sends Address Resolution Protocol messages onto a local area network.
The exploit that occurred is a privilege escalation attack, allowing a non-administrative user to perform administrative tasks.Therefore the Correct Option Is a. privilege escalation.
The Correct Answer Is a. privilege escalation. This exploit allows a user to gain elevated access to resources that are typically restricted for higher-level accounts.
Here are definitions of the incorrect options:
DNS cache poisoning: This attack involves substituting addresses in the DNS cache so that the computer is redirected to another device.Man-in-the-middle: This is where the attacker intercepts communication between two parties and can modify or eavesdrop on the conversation.ARP poisoning: In this attack, falsified ARP messages are sent over the local network to link the attacker’s MAC address with the IP address of a victim, allowing unauthorized access.The general syntax for the function prototype to overload the assignment operator = for a class is ____.a. friend className& operator=(const className&);b. const className& operator=(const className&);c. className& operator=(className&);d. string className& operator=(className&);
Answer:
Option (B) is the correct answer to the following question.
Explanation:
Here, in the code "const" is the constant keyword which is used when we need that the value stored in that variable will never change.
The following option is correct because the assignment operator are those operator which initialize the value in the variable and overloading of the assignment operator would be as we use the other operators and also we could use them by creating the objects as we use in the copy constructor.
So, that's why the following option is correct.

This morning you modified five large data files in your home folder in Linux, and now you want to find and delete the files because you no longer need them. Which of the following commands can you use to list and sort files based on the time they were modified
Answer:
ls -t
Explanation:
"ls" command in Linux is used very often. It lists the directory contents. The "ls" utility is part of the core utilities and installed in all Linux distributions.
When ls command is used with "-t" , "ls -t" sorts files/directories list by date created or modified.
More advanced version is "ls -lt", where it sorts by date and shows info about directory, size, modified date and time, file or folder name and owner of file and its permission.
The following code accomplishes which of the tasks written below? Assume list is an int array that stores positive int values only.int foo = list[0];for (int j =1 ; j < list.length; j++) if (list[j] > foo) foo = list[j];
Answer:
The code mention in question will find "Largest Number in list"
Explanation:
In first line of code
first element of array will be move in "foo" variable
then loop will start from 2nd value and ends at last value of array
in next step
2nd value of array compares with 1st value
If 2nd value is greater than 1st then greater value move into "foo" variable.
This process continues till the end of array.
after completion largest element of array will be present in "foo".
