Answer:
Option (b) is the correct answer.
Explanation:
Here in option "D", "C" language is used, so the answer is given on the behalf of "C" language and in "C" language, the String is written in double quotes which are opposite of option "b" hence it is a wrong statement. hence it is the correct option for this question.
The String is also called a word in the English language which is made of character. So in C programming language, a user needs to create a character array to store the string because the array is used to create multiple variables of the same type and variable is used to store the data.
In any programming language character array is used to store the string but for back-end and the user uses String data type for the front-end.
Option a states that the string is made up of character, letter, digits and special symbol which is correct.Option c states that a string is assigned on the character array which is correct.Option d states that the last character of the "String" is the "NULL" character which is also right.
The false statement is B) String literals are written inside of single quotes.
Explanation:The false statement among the given options is B) String literals are written inside of single quotes. In programming languages like C, C++, and Java, string literals are written inside double quotes, not single quotes. For example, "Hello, World!" is a string literal.
A company has made the decision to host their own email and basic web services. The administrator needs to set up the external firewall to limit what protocols should be allowed to get to the public part of the company's network. Which ports should the administrator open? (Choose three.)
Answer:
Port 25
Port 53
Port 80
Explanation:
Port 25 is to be used for relaying messages between MTAs (Mail Transfer Agents) or from MSAs (Mail Submission Agents) to MTAs.
Port 53 is used by the Domain Name System (DNS), a service that turns human readable names like AuditMyPc.com into IP addresses that the computer understands. Because port 53 is usually open, malicious programs may attempt to communicate on it.
On a Web server or Hypertext Transfer Protocol daemon, port 80 is the port that the server "listens to" or expects to receive from a Web client, assuming that the default was taken when the server was configured or set up. By default, the port number for a Web server is 80.
Write an abstract superclass encapsulating a college applicant:
A college applicant has two attributes: the applicant’s name and the college the applicant is applying to.
This class has two non-abstract subclasses: one encapsulating an applicant for undergraduate school, and the other encapsulating an applicant for graduate school.
An applicant for undergraduate school has two attributes: a SAT score and a GPA. An applicant for graduate school has one additional attribute: the college of origin.
It also has a method that returns "from inside" if the college of origin is the same as the college applied to; otherwise, it returns "from outside".
You also need to include a class to test two classes.Java please.
Answer:
The code snippet file is attached. There are four files:
Abstract Applicant ClassThe Graduate ClassThe Undergraduate classThe TestApplicantClassThe code is well commented and explanatory.
Explanation:
In evaluating a loop, you find the following statement:
"value += 1".
What happens to the value variable upon each iteration of the loop?
Group of answer choices:
A. The variable's value is changed to a positive value.
B. The variable is reset to an int type, with a value of 1.
C. The variable is incremented by itself.
D. The variable is increased by 1 each iteration through the loop.
Answer:
D) The variable is increased by 1 each iteration through the loop
Explanation:
In Most popular programming languages such as java, c++, python etc, there is a variance to the simple assignment operator. (=). This variance is called a compound assignment operator. Compound operators come in different styles for example
x = x+1 equivalent x+=1
x = x-1 equivalent x- =1
x = x/y equivalent x/=y
In the question scenario value += 1 is equivalent to value = value+1. Compound operators are important in providing short hands while coding as well as helping the programmer from having to cast variable types explicitly
________ symbol is used in the "Advanced" section of the time range picker to round down to nearest unit of specified time.
Answer:
@(at sign) is the correct answer to the following statement.
Explanation:
Because the following symbol is the "at sign" symbol that is used for the Advanced section in the time range picker that lets the user search for the specified time for the round down the closest entity of a particular period. So, that's why the following answer is correct for the following statement.
A dictionary attack works by hashing all the words in a dictionary and then comparing the hashed value with the system password file to discover a match.
A. True
B. False
Answer:
True
Explanation:
A dictionary attack is an attempts to gain illegal access to a computer system by hashing all the words in a dictionary and then systematically entering each hashed value as a password so as to discover a match. it has been the most successful password guessing technique over the years because many users and organization use ordinary words as passwords.
What should you double check for some reason its not working? You have created a workflow rule to send an email in your configuration sandbox.
A. You have the correct email address
B. HTML does not work in sandbox, make sure your email has no HTML
C. Check the deliverability settings
D. Look at the system audit trail
Answer:
Option A and C are the correct options
Explanation:
The following options is true because when the user created the flow of the work rule for sending an email in their configuration sandbox then, the user correct these email address and also users can examine their deliverability setting.
Option B is false because the HTML also works in the sandbox.
Option D is false because the audit trail did not look at the system.
#include ... void sig_handler(){ static int i = 1; printf("Beep\n"); alarm(i); ++i; } int main(){ struct sigaction sa; sa.sa_flags = 0; sa.sa_handler = sig_handler; if(sigaction(SIGALRM, &sa, NULL) != 0){ printf("Failed to bind handler.\n"); exit(1); } printf("Going into an infinite loop.\n"); alarm(1); while(1); return 0; }
Suppose the above program is run for 7.5 seconds after it prints "Going into an infinite loop". The program is run multiple times where the "system load" from other processes sharing the cpu will vary from none to many other processes. Which best characterizes how many times "Beep" is printed?
Answer:
Explained below
Explanation:
After the compiling the program it prints "Going to infinite loop" after that i started the timer till 4.5 sec. The program prints more than 4 beeps nearly 6-7 beep messages were printed.
The number "Beep" would always be strictly greater than 4.
Hence, if the above program is run for 7.5 seconds after it prints "Going in an infinite loop", it will print Beep for about 9-10 times. Hence, the number will always be greater than 7
Write a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program should first ask for the number of years. The outer loop will iterate once for each year. The inner loop will iterate four times, once for each quarter. Each iteration of the inner loop will ask the user for the inches of rainfall for that quarter.
Answer & Explanation:
Written in java
import java.util.Scanner;
public class Main{
public static void main(String[] args) {
int totalRainfall = 0;
int rainfall;
Scanner keyboard = new Scanner(System.in);
int year;
do {
System.out.println("Enter number of year(s): value must be greater than 0");
year = keyboard.nextInt();
} while (year < 1);
// {
//
// System.out.println("Invalid input, please enter a number greater than zero ");
//
// year = keyboard.nextInt();
//
// }
for (int i = 0; i < year; i++) {
for (int quarter = 1; quarter <= 4; quarter++) {
int currentYear = 1 + i;
System.out.println("Enter the inches of rainfall for year " + currentYear + " quarter " + quarter);
rainfall = keyboard.nextInt();
if(rainfall > -1){
totalRainfall += rainfall;
}
while (rainfall < 0) {
System.out.println("Enter the inches of rainfall for year " + currentYear + " quarter " + quarter +": value must be greater or equal to 0 ");
rainfall = keyboard.nextInt();
}
}
}
System.out.println("Average quarterly rainfall is: " + (totalRainfall/(year*4)));
System.out.println("Average yearly rainfall is: " + (totalRainfall/(year)));
}
}
Final answer:
A Python program is provided that calculates the average rainfall over a number of years. User inputs the number of years, then for each quarter of each year, the rainfall in inches. The program computes and outputs the average rainfall in inches and converts it to millimeters.
Explanation:
The program to calculate the average rainfall over a period of years will involve two nested loops. The outer loop will iterate through the number of years, while the inner loop will iterate through each quarter of a year. For each quarter, the program will collect the rainfall data in inches and calculate the average, eventually converting the final result to millimeters.
Python Code Example:
years = int(input('Enter number of years: '))
total_rainfall = 0
for year in range(1, years + 1):
for quarter in range(1, 5):
rainfall = float(input(f'Enter the inches of rainfall for year {year} quarter {quarter}: '))
total_rainfall += rainfall
average_rainfall_inches = total_rainfall / (years * 4)
average_rainfall_mm = average_rainfall_inches * 25.4
print(f'The average rainfall over {years} years is {average_rainfall_inches} inches or {average_rainfall_mm} mm.')

Which of the following is the definition of registration authority ( RA)?
a. The process of applying an algorithm to cleartext (or plain text) data, resulting in a ciphertext.
b. The certificate authority’s list of invalid certificates.
c. The concept of ensuring that an originator cannot refute the validity of a statement or document.
d. An entity that is responsible for the registration and initial authentication of certificate subscribers.
Answer:
The correct answer following question will be Option D.
Explanation:
An authority that verifies the user requests for digital certificates and tells to the CA (Certificate authority) to issue the certificates, known as Registration Authority (RA). The digital certificate contains a key named "public key" which is used to encrypt and decrypt digital signatures.
Hence, registration authority, it's an entity that is responsible for the authentication of certificate and registration and the other given options are not relatable to this authority.
So, option D is the correct answer.
To create the array variable named ar, you would use :A. int ar;
B. int() ar;
C. int[] ar;
D. None of these
Answer: (C)
Explanation:
You can declare it as:
int[ ] ar; or
int ar[ ];
Final answer:
To create an array variable named 'ar', the correct syntax is 'int[] ar;'. This declares 'ar' as an array of integers,
Therefore, the correct answer is option c 'int[] ar;'
Explanation:
To create an array variable named ar in many programming languages such as Java, you would use the syntax provided in option C: int[] ar; This line of code defines an array of integers. The square brackets ([]), which come after the data type, tell the compiler that this variable will be used as an array, which can store multiple values of the specified type, in this case, integers.
