Which of the following JavaScript methods is used to define an object collection based on a CSS (Cascading Style Sheets) selector? a. object.style.property = ""value(selector)"" b. object.property = ""value(selector)"" c. document.getElementbyId(selector) d. document.querySelectorAll(selector)
Answer:
The answer is option d.
Explanation:
The 'querySelectorAll' function enables you to extract the list of items that fit the CSS selector you choose. It's just a way to find JavaScript components. It is very adaptable and enables you to search for tags, classes, IDs, combinations of parent/child, attributes, etc.
In other words, we can say that the querySelectorAll() method returns all the matches. and other options are not correct that can be described as follows:
In option a and b, the object is a collection of unordered properties, that can be changed in adding, deleting and read-only. The option a is an attribute, that is used in CSS and option b is used in JavaScript for the property name. In option c, It reverts the element with the fixed value, that has the ID attribute.What is the formula to find the sum of cells a1 a2 and a3

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.
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.

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".
5.Consider the following code snippet:ArrayList arrList = new ArrayList();for (int i = 0; i < arrList.size(); i++){ arrList.add(i + 3);}What value is stored in the element of the array list at index 0? Think carefully about this.A. 0B. 3C. 6D. None
Answer:
The answer to this question is the option "D".
Explanation:
In the given question code we use the array list that does not store any value in the index 0, because for adding elements in the list, we use add function. In this function parameter, we pass the value that is "i+3". Which means the value of i is increased by 3. In option A, B and C we do not assign any value in the add function. so, it not correct.That's why the correct answer to this question is the option "D".
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.
What would be the results of the following code?final int SIZE = 25;int[] array1 = new int[SIZE];... // Code that will put values in array1int value = 0;for (int a = 0; a < array1.length; a++){value += array1[a];}a.value contains the highest value in array1b.value contains the lowest value in array1c.value contains the sum of all the values in array1d.This would cause the program to crash
Answer:
The correct option to this code is "a".
Explanation:
The given code contains the highest value in array1 because code will use variable value that adds all value of array1. and other options are not correct that can be described as:
In option, b The value variable, we add a number that's why it can not contain the lowest value.In option, c The value variable use for loop for add all array element not sum of values.In option, d There will no crash in program.
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".

Which of the following is the closest RAID level the technician should deploy while minimizing the number of disks and maintaining fault tolerance.
Answer:
RAID level 5 can be used to compensate a limited number of available disks.
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 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:
In the function body the value of balance variable is not return that means we use void return type .The void return type is used when the function does not return any value .
If the function are int return type that means it return "integer value ".
if the function are double return type that means it return the "double value" .
The complete implementation of this method is
public void deposit(double amount) // function definition
{
balance = balance + amount; // statement
}
