Answer:
The correct answer is C - Object-oriented design.
Explanation:
Object-oriented design defines code or software as objects. These objects represent instances of a real-life situation. For example, an animal class consist of a dog, cat, lion. A dog therefore is n instance of the animal class.
Objects are described as having properties and behaviours. Properties are variables, arrays, sets, maps etc and behaviours are the functions and methods that manipulate these data.
Object-oriented programming is done based on this design.
g Write a function that collects integers from the user until a 0 is encountered and returns then in a list in the order they were input.
Answer:
The function written in python is as follows;
def main():
user_input = int(input("Input: "))
mylist = []
while not user_input == 0:
mylist.append(user_input)
user_input = int(input("Input: "))
print(mylist)
if __name__ == "__main__":
main()
Explanation:
This line declares a main function with no arguments
def main():
This line prompts user for input
user_input = int(input("Input: "))
This line declares an empty list
mylist = []
The following iteration checks if user input is not 0; If yes, the user input is appended to the list; otherwise, the iteration ends
while not user_input == 0:
mylist.append(user_input)
user_input = int(input("Input: "))
This liine prints the list in the order which it was inputted
print(mylist)
The following lines call the main function
if __name__ == "__main__":
main()

Recall that within our BinarySearchTree class the root variable is of type BSTNode. A BSTNode object has three attributes: info of class T, left of class BSTNode, and right of class BSTNode, Following is the implementation of the isEmpty method: public boolean isEmpty() // Returns true if this BST is empty; otherwise, returns false.
{
return (root == null);
}
A. True
B. False
Answer:
False ( A )
Explanation:
The implementation is incorrect hence the return would be false and this is because : root.left is supposed to be NULL, root.right is supposed to be NULL and when these conditions are met then the Binary tree would be empty.
The condition for the above statement would be represented as
if( root.left = = null && root.right == null &&root.info == null)
return true;
else
return false;

Write a function that returns a chessboard pattern ("B" for black squares, "W" for white squares). The function takes a number N as input and generates the corresponding board.
Input The first line of the input consists of an integer- num, representing the size of the chessboard.
Output Print N lines consist of N space-separated characters representing the chessboard pattern.
Answer:
Here is the C++ program.
#include <iostream> //to use input output functions
using namespace std; // to access objects like cin cout
void chessboard(int N){ // function that takes a number N as parameter generates corresponding board
int i, j;
string black = "B"; // B for black squares
string white = "W"; // W for white squares
for(i=1;i<=N;i++){ //iterates through each column of the board
for(j=1;j<=N;j++){ //iterates through each row of the board
if((i+j)%2==0) // if sum of i and j is completely divisible by 2
cout<<black<<" "; //displays B when above if condition is true
else //if (i+j)%2 is not equal to 0
cout<<white<<" "; } // displays W when above if condition is false
cout<<endl; } } //prints the new line
int main(){ //start of the main function
int num; //declares an integer num
cout << "Enter an integer representing the size of the chessboard: "; //prompts user to enter size of chess board
cin >> num; //reads value of num from user
chessboard(num); } //calls chessboard function to display N lines consist of N space-separated characters representing the chessboard pattern
Explanation:
The function works as follows:
Lets say that N = 2
two string variables black and white are declared. The value of black is set to "B" and value of white is set to "W" to return a chessboard pattern in B and W squares.
The outer loop for(i=1;i<=N;i++) iterates through each column of the chess board. The inner loop for(j=1;j<=N;j++) iterates through each row of chess board.
At first iteration of outer loop:
N = 2
outer loop:
i=1
i<=N is true because i=1 and 1<=2
So the program enters the body of the outer for loop. It has an inner for loop:
for(j=1;j<=N;j++)
At first iteration of inner loop:
j = 1
j<=N is true because j=1 and 1<=2
So the program enters the body of the inner for loop. It has an if statement:
if((i+j)%2==0) this statement works as:
if(1+1) % 2 == 0
(1+1 )% 2 takes the mod of 1+1 with 2 which gives the remainder of the division.
2%2 As 2 is completely divisible by 2 so 2%2 == 0
Hence the if condition evaluates to true. So the statement in if part executes:
cout<<black<<" ";
This prints B on the output screen with a space.
B
The value of j is incremented to 1.
j = 2
At second iteration of inner loop:
j = 2
j<=N is true because j=2 and 2=2
So the program enters the body of the inner for loop. It has an if statement:
if((i+j)%2==0) this statement works as:
if(1+2) % 2 == 0
(1+2 )% 2 takes the mod of 1+2 with 2 which gives the remainder of the division.
3%2 As 3 is not completely divisible by 2
Hence the if condition evaluates to false. So the statement in else part executes:
cout<<white<<" ";
This prints W on the output screen with a space.
B W
The value of j is incremented to 1.
j = 3
Now
j<=N is false because j=3 and 3>2
So the loop breaks and program moves to the outer loop to iterate through the next row.
At second iteration of outer loop:
N = 2
outer loop:
i=2
i<=N is true because i=2 and 2 = 2
So the program enters the body of the outer for loop. It has an inner for loop:
for(j=1;j<=N;j++)
At first iteration of inner loop:
j = 1
j<=N is true because j=1 and 1<=2
So the program enters the body of the inner for loop. It has an if statement:
if((i+j)%2==0) this statement works as:
if(2+1) % 2 == 0
(2+1 )% 2 takes the mod of 2+1 with 2 which gives the remainder of the division.
3%2 As 3 is not completely divisible by 2
Hence the if condition evaluates to false. So the statement in else part executes:
cout<<white<<" ";
This prints W on the output screen with a space.
B W
W
The value of j is incremented to 1.
j = 2
At second iteration of inner loop:
j = 2
j<=N is true because j=2 and 2=2
So the program enters the body of the inner for loop. It has an if statement:
if((i+j)%2==0) this statement works as:
if(2+2) % 2 == 0
(2+2 )% 2 takes the mod of 2+2 with 2 which gives the remainder of the division.
4%2 As 4 is completely divisible by 2 so 4%2 == 0
Hence the if condition evaluates to false. So the statement in if part executes:
cout<<black<<" ";
This prints B on the output screen with a space.
B W
W B
The value of j is incremented to 1.
j = 3
Now
j<=N is false because j=3 and 3>2
So the loop breaks and program moves to the outer loop. The value of outer loop variable i is incremented to 1 so i = 3
N = 2
outer loop:
i=3
i<=N is false because i=3 and 3>2
So this outer loop ends.
Now the output of this program is:
B W
W B

7.1 Describe the six clauses in the syntax of an SQL retrieval query. Show what type of constructs can be specified in each of the six clauses. Which of the six clauses are required and which are optional
Answer:
Answered below
Explanation:
The syntax of an SQL retrieval query is made up of six clauses. In the order in which they are used, they consist of: SELECT, FROM, WHERE, GROUP BY, HAVING and order by.
Of all these clauses, the SELECT clause and the FROM clause are required and must be included. They are the first two used to begin the retrieval query. The others are optional.
The SELECT clause allows you to choose the columns you want to get information or data, from.
The FROM clause identifies the table where the information is being retrieved.
The WHERE clause specifies a condition for the retrieval of information.
You use the GROUP BY clause to group your data in a meaningful way.
You use the HAVING clause to specify a condition on the group.
The ORDER BY clause is used to order results rows in descending or ascending order.

An OS X backup utility that automatically backs up files to a dedicated drive that is always available when the computer is turned on is called ____________.
Answer:
Time machine.
Explanation:
An OS X backup utility that automatically backs up files to a dedicated drive that is always available when the computer is turned on is called a time machine.
OS X was released in 2001 and it's Apple's version ten (10) of the operating system that runs on its Macintosh computers.
A time machine is a software tool built into the Mac operating system and it is primarily designed to automatically backup user files or data onto a dedicated drive such as an external hard drive disk through a wired connection, by using a Thunderbolt or universal serial bus (USB) cable. The automatic backup can as well be done wirelessly through a network connection.
Write a function that takes any word and applies that pattern. I.E. printer =? p5r ; *** =? v2a ; function =? f6n
Answer:
I am writing a JAVA program:
import java.util.Scanner; //used to take input from user
public class Main{
public static void function(String word){ //function that takes a word as parameter an applies a pattern
int count=0; // count the number of characters between first and last characters of the word string
char first = word.charAt(0); //gets the first character of the word
char last = word.charAt(word.length() - 1); /gets the last character
for(int i = 1; i<word.length()-1;i++) //iterates through word to count the characters between first and last characters
{ count=i; } //sets the count of characters to count variable
System.out.println(first+""+count+""+last); } //prints the first and last characters of input word with the number of characters between first and last characters of word string
public static void main(String []args){//start of main function
Scanner input= new Scanner(System.in); //creates Scanner class object
System.out.print("Enter a word: "); // prompts user to enter a word
String str= input.nextLine(); //reads word string from user
function(str); } } //calls function passing the string to it
Explanation:
I will explain the program with the help of an example:
Suppose the word is printer.
charAt(0) returns the character at the 0-th index of a string word i.e printer. This means the first character of "printer" is returned i.e. 'p'
word.charAt(word.length() - 1) returns the character at the word.length() - 1 index of a string word i.e printer. This means the last character of "printer" is returned i.e. 'r'. Here length() function is used to return the length of the string. The length of "printer" is 7 (from 0 to 6) so word.length() -1 returns 7-1 = 6. This means the character at 6th index.
for(int i = 1; i<word.length()-1;i++) loop counts the character between the first and last character of "printer" . It works as follows:
1st iteration:
i = 1
i<word.length()-1 is true because 1<6
count = i
count = 1
i = i + 1
i = 2
2nd iteration:
i = 2
i<word.length()-1 is true because 2<6
count = i
count = 2
i = i + 1
i = 3
3rd iteration:
i = 3
i<word.length()-1 is true because 3<6
count = i
count = 3
i = i + 1
i = 4
4th iteration:
i = 4
i<word.length()-1 is true because 4<6
count = i
count = 4
i = i + 1
i = 5
5th iteration:
i = 5
i<word.length()-1 is true because 5<6
count = i
count = 5
i = i + 1
i = 6
At next iteration i<word.length()-1 evaluates to false because i = 6
So final value of count is:
count = 5
System.out.println(first+""+count+""+last); statement prints the first character of "printer" i.e. 'p', followed by value of count i.e. 5 , followed by last character of "printer" i.e. 'r'
Output:
p5r
A customer complains that her desktop computer will not power on. What initial actions should you take?
Answer:
Test The Components and the motherboard
Explanation:
Well, im going to assume that she turned on the pc and the screen is completely black, nothing being displayed but the fans are spinning. The first thing i would do is test the components to see if its working or not. What i would do first is test the components. I would start from the RAM, Video Card (If it has one) CPU, PSU, and motherboard. I would also take out the CMOS battery and put it back in after a while to clear the bios settings if the customer messed with the bios settings. Make sure to test the motherboard and check for physical damage (Fried Areas, blown capacitors, water Damage etc.) And if you cant find any physical damage try testing the motherboard and see if its dead or not. Also try checking if all of the cables are plugged in all the way, like a loose HDMI cable, loose psu cable etc. Also make sure the psu is connected to power
Also, this is my first brainly answer. Yay :)
Initials action we should take are as follows,
Check that all of the cables are fully plugged in.Ensure that power supply is turned on.After that, i will check for faulty power cable.Now open CPU and check parts and devices one by one such as RAM, SMPS etc.These are the initial actions we should take when computer is not powering on.

Data_____is defined as the condition in which all of the data in the database are consistent with the real-world events and conditions.
a. ubiquity.
b. quality.
c. anomaly.
d. integrity.
Answer:
d. integrity
Explanation:
Data integrity is defined as the condition in which all of the data in the database are consistent with the real-world events and conditions.
Data integrity can be used to describe a state, a process or a function – and is often used as a proxy for “data quality”. Data with “integrity” is said to have a complete or whole structure. Data integrity is imposed within a database when it is designed and is authenticated through the ongoing use of error checking and validation routines. As a simple example, to maintain data integrity numeric columns/cells should not accept alphabetic data.
