Answer:
Running queries in SQL or structured query language interacts with a relational database. It is used to create new databases and tables, read the content of the database tables, update and also delete the content.
Microsoft Access is a database software but Excel is a spreadsheet application.
Explanation:
Access databases hold large datasets that can be accessed from other platforms and generate automatic query while datasets in Excel are limited but it has comprehensive statistical tools for data analysis.
JAVA...Write a statement that calls the recursive method backwardsAlphabet() with parameter startingLetter.
CODE BELOW
public class RecursiveCalls {
public static void backwardsAlphabet(char currLetter) {
if (currLetter == 'a') {
System.out.println(currLetter);
}
else {
System.out.print(currLetter + " ");
backwardsAlphabet(--currLetter);
}
}
public static void main (String [] args) {
char startingLetter;
startingLetter = 'z';
/* Your solution goes here */
}
}
Answer:
RecursiveCalls.backwardsAlphabet(startingLetter);
Explanation:
The statement that is needed is a single-line statement. Since the class RecursiveCalls is already in the same file we can simply use that class and call its function without making a new class object. Once we call that class' function we simply pass the variable startingLetter (which is already provided) as the sole parameter for the function in order for it to run and use the letter 'z' as the starting point.
RecursiveCalls.backwardsAlphabet(startingLetter);

Using complete sentences post a detailed response to the following.
Have you ever tried to learn a new language or do you have friends who've had that experience? What are some of the
steps you would take to learn a new language, and what are some challenges that might arise? What are some things that
can help make the process easier?
Have you ever tried to learn a new language or do you have friends who've had that experience?
Yes, I tried to learn Python and I even managed to do two Discord bots which are (somewhat) functional, but I'm far to say that I've managed to lean the language completly. There are lots of things to learn on a language as Python.
I also leant PHP on my own and managed to do a website (somehow) functional.
What are some of the steps you would take to learn a new language, and what are some challenges that might arise?
The first steps in learning any computer language is learning the syntax. If you manage to do that, with the experience you gained from previous projects/languages you might be able to create something working. At times you might feel down if the project doesn't work as expected.
What are some things that can help make the process easier?
Video tutorials, experiments and searching questions and problems on Google is a very important resource.
One vulnerability that makes computers susceptible to walmare is:
A. A using antimalware software
B. Using password software
C. Using old versions of software
D. Using encryption on sensitive files
What is the main advantage of using a WYSIWYG (“what you see is what you get”) editor when constructing a website?
Only one programming language is required.
Websites may have more professional construction.
Knowledge of HTML is not required.
Website templates are not necessary.
Answer:
The answer to this question is given below in the explanation section.
Explanation:
The correct answer among the given options to this question is:
Knowledge of HTML is not required.
Because when you are constructing a website using WYSIWYG (“what you see is what you get”) editor, then you don't need the knowledge of HTML. Because, when you use WYSIWYG editor to insert button, table, images, text, paragraph, etc. It will automatically insert HTML code behind the page. For example, you can insert a form and a submit button using drag and drop with the help of WYSIWYG (“what you see is what you get”) editor, for this purpose, you don't need exact knowledge of HTML. WYSIWYG (“what you see is what you get”) automatically inserts the HTML for the form and button on a website page.
While other options are not correct because:
Using the WYSIWYG (“what you see is what you get”) editor, you can use different programming languages in your website, such as VB.net, Asp.Net, C#, Javascript, Bootstrap, etc. It is not necessarily that you may have more professional construction and in WYSIWYG (“what you see is what you get”) website templates are mostly used and modified using WYSIWYG editor.
Answer:
(C):Knowledge of HTML is not required.

Answer:
#include <iostream>
using namespace std;
int main() {
int num, check=0;
for(int num = 1; num<=100;num++){
for(int i = 2; i <= num/2; i++) {
if(num % i == 0) {
check=1;
break; } }
if (check==0) { cout <<num<<" "; }
check = 0;
}
return 0;
}
Explanation:
This line declares num as integer which represents digits 1 to 100.
A check variable is declared as integer and initialized to 0
int num, m=0, check=0;
This for loop iterates from 1 to 100
for(int num = 1; num<=100;num++){
This iterates from 2 to half of current digit
for(int i = 2; i <= num/2; i++) {
This checks for possible divisors
if(num % i == 0) {
If found, the check variable is updated to 1
check=1;
And the loop is terminated
break; } }
The following if statement prints the prime numbers
if (check==0) { cout <<num<<" "; }
check = 0;
}
Professor Gig A. Byte needs to store text made up of the characters A with frequency 6, B with frequency 2, C with frequency 3, D with frequency 2, and E with frequency 8. Professor Byte suggests using the variable length codes:
Character Code
A 1
B 00
C 01
D 10
E 0
The professor argues that these codes store the text in less space than that used by an optimal Huffman code. Is the professor correct?
Answer:
This is not true
Explanation:
The optimal Huffman code is used to encrypt and compress text files. It uses fixed-length code or variable-length code for encryption and compression of data.
The professor's character code is similar to Huffman's variable-length coding which uses variable length od binary digits to represent the word strings. The file size of the text file above is;
= 6 x 1 + 2 x 2 + 3 x 2 + 2 x 2 + 8 x 1 = 28 bits
This would be the same for both cases.
The encrypt would be the problem as the encoded and decoding of the characters B and E may cause an error.
Write a program that calculates the average of N integers. The program should prompt the
user to enter the value for N and then afterward must enter all N numbers. If the user enters a
negative value for N, then an exception should be thrown (and caught) with the message “ N
must be positive.” If there is any exception as the user is entering the N numbers, an error
message should be displayed, and the user prompted to enter the number again.
Answer:
def Average(num):
if num == 0:
return 0
val = 0
trueNum = num
for i in range(0, num):
try:
val += int(input("Enter value (%d out of %d): " % (i+1,num)))
except Exception as e:
print ("Error processing value. Non integer detected.")
try:
val += int(input("Enter value (%d out of %d): " % (i+1,num)))
except Exception as e:
print ("Error processing value. Non integer detected.")
print ("OMITTING value from average.")
trueNum -= 1
return val/trueNum
def main():
try:
num = int(input("Enter a value N for amount of items: "))
if num < 0:
raise(ValueError)
except ValueError:
print ("N must be positive integer.")
exit(1)
print("Average: ", Average(num))
exit(0)
if __name__ == "__main__":
main()
Explanation:
This program is written in Python to collect some integer value from the user as an upper bound of integers to be input for an average. Using this upper bound, the program checks to validate it is indeed an integer. If it not an integer, then the program alerts the user and terminates. If it is a user, the Average function is called to begin calculation. Inside the Average function, the user is prompted for an integer value repeatedly up until the upper bound. Using the sum of these values, the program calculates the average. If the user inputs a non integer value, the program will alert the user that the value must be an integer and ask again. If the user again inputs a non integer value, that iteration will be omitted from the final average. The program this prints the calculated average to the user.

Write a recursive function that accepts two arguments into the parameters x and y. The function should return the value of x times y. Hint: multiplication can be performed as repeated addition. Test your recursive function by prompting the user to enter values for x and y and then displaying the result. Your function should be able to handle multiplication of negative values.
Answer:
In Python:
def times(x,y):
if y<0:
return -1*times(x,y*-1)
if y == 1:
return x
return x + times(x,y-1)
x = int(input("x: "))
y = int(input("y: "))
print(times(x,y))
Explanation:
I answered the question using Python3
This defines the function
def times(x,y):
This checks for negative values
if y<0:
return -1*times(x,y*-1)
This is the base case where y = 1
if y == 1:
If true, the value of x is returned
return x
This returns the recursion and it is repeated until the base case is achieved
return x + times(x,y-1)
This prompts user for x value
x = int(input("x: "))
This prompts user for y value
y = int(input("y: "))
This calls the recursion and also prints the result
print(times(x,y))
What are stored procedures? What kind of attack do stored procedures protect from? Identify two reasons why stored procedures are a good mitigation against the specific attack. g
Answer:
Stored procedures or procedures are subroutines or subprograms in SQL written by the user to accomplish a certain task. it helps to mitigate SQL injection by using markers as placeholders for data input and it streams the query statement and data separately in the database.
Explanation:
The stored procedure used in SQL is a user-defined function. Unlike built-in functions like pi(), they must be called to use them.
SQL injection in query statements is written by hackers to bypass conditions, especially when trying to gain access to other user accounts. Stored procedures use markers or placeholders to prevent this.
Write two statements that each use malloc to allocate an int location for each pointer. Sample output for given program:
numPtr1 = 44, numPtr2 = 99
#include
#include
int main(void) {
int* numPtr1 = NULL;
int* numPtr2 = NULL;
/* Your solution goes here */
*numPtr1 = 44;
*numPtr2 = 99;
printf("numPtr1 = %d, numPtr2 = %d\n", *numPtr1, *numPtr2);
free(numPtr1);
free(numPtr2);
return 0;
}
Answer:
#include <stdio.h>
#include <stdlib.h>
int main(void) {
int* numPtr1 = NULL;
int* numPtr2 = NULL;
/* Your solution goes here */
numPtr1 = (int *) malloc(10);
numPtr2 = (int *) malloc(20);
*numPtr1 = 44;
*numPtr2 = 99;
printf("numPtr1 = %d, numPtr2 = %d\n", *numPtr1, *numPtr2);
free(numPtr1);
free(numPtr2);
return 0;
}
Explanation:
The C library malloc function is used to assign memory locations (in bytes) to variables. It accepts the size parameter and returns a pointer to the specified variable location.
The two malloc statements above assign two memory locations 10 and 20 to the numPtr1 and numPtr2 integer variables respectively.
If you have 128 oranges all the same size, color, and weight except one orange is heavier than the rest. Write down a C++ Code/Algorithm to search the heavy orange, in how many steps would you be able to find it out?
Answer:
#include <iostream>
using namespace std;
void Search_heavy_orange(int arr[], int l, int r, int x)
{
int count = 0, m = 0;
while (l <= r) {
m = l + (r - l) / 2;
// Check if x is present at mid
if (arr[m] == x) {
count++;
}
// If x greater, ignore left half
if (arr[m] < x) {
l = m + 1;
count++;
}
// If x is smaller, ignore right half
else {
r = m - 1;
count++;
}
}
cout << "............For Worst Case......." << endl;
cout << "Orange with heavy weight is present at index " << m << endl;
cout << "Total number of step performed : " << count << endl;
}
int main()
{
// Assuming each orange is 100 gm and the weight of heavy
// orange is 150 gm
int orange_weight[128];
for (int i = 0; i < 127; i++) {
orange_weight[i] = 100;
}
// At worst case the heavy orange should be at last position
// inside the basket : 127
orange_weight[127] = 150;
// We will pass array , start index , last index and the search element
// as the parameters in the function Search_heavy_orange
Search_heavy_orange(orange_weight, 0, 127, 150);
return 0;
}

What is an information?An information refers to something that has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed.
The digital signals and other data use discrete signs or alogrithms to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and the electrical currents convey information in a more continuous form.
Information is not knowledge itself, but its interpretation is important. An Information can be in a raw form or in an structured form as data. The information available through a collection of data may be derived by analysis by expert analysts in their domain.

Which vulnerability can occur if a programmer does not properly validate user input and allows an attacker to include unintended SQL input that can be passed to a database?
Answer:
SQL injection
Explanation:
SQL injection is a vulnerability in databases that occurs when user input is not properly validated. Hackers are able to input SQL query statements to bypass the use of the actual user name and password to gain access to the account.
Using placeholders in programmed SQL statements mitigates the effects of SQL injection.
