Which of the following is NOT a reason to include comments in programs?
a. Comments help the computer decide whether certain components of a program
are important.
b .Comments help programmers debug issues in their own code
c. Comments help document how code was written for other programmers to use
d. Comments enable programmers to track their work throughout the development
process
Answer:
A Would be correct!
Explanation:
The reason for this is because in a code when you use the comment out the compiler will skip over it and will not do anything and will skip it. So the comment can help the computer do anything!
HOPE THIS HELPED MAKE ME THE BRAINLIST!
Using programming concepts, the option that is NOT a reason to include comments in a code is:
a. Comments help the computer decide whether certain components of a program are important.
-------------------------
Usually, codes are very long, and each person is responsible for a part of the problem. The parts have to be intervened with each other, and thus, sometimes a programmer will have to look at another part of the code, not coded by him. Thus, for the programmer and other people working in the project to understand, comments are important.Additionally, the comments are used to help the programmers debug their own code, as they can go part by part and see what is done in each part, also helping them work throughout the development process.In a program, there may be some components that end up not being necessary, but this is not decided by comments, and thus, option A is not a reason to include comments in programs.A similar problem is given at https://brainly.com/question/13527834
We are designing a program that must do the following:
Read 3 integers from a file called "data.txt"
Sum the integers
Compute the mean of the integers
Output the mean to a file called "mean.txt".
We are required to select functions from the library provided below to complete our program. Inside of the main () function, fill in the correct C statements to satisfy the four requirements listed above. You must fill in all the lines labeled with "statement x", where x is 2, 3, 4, 5, or 6. The first statement has been completed for you.
// These are the library functions that we must invoke!
// Precondition: The input file must already be open.
int read_integer (FILE *infile)
{
int number = 0;
fscanf (infile, "%d", &number);
return number;
}
int calculate_sum (int number1, int number2, int number3)
{
int sum = 0;
sum = number1 + number2 + number3;
return sum;
}
double calculate_mean (int sum, int number)
{
double mean = 0.0;
mean = ((double) sum) / number;
return mean;

Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get total of four cards from each different suit and display the four cards picked (it is possible that a card may be picked twice). Here is a sample run of the program:
4 of Diamonds
8 of Spades
Queen of Clubs
8 of Hearts
Number of picks: 9
Answer:
Here is the JAVA program:
public class Main { //class name
public static void main(String[] args) { //start of main method
//sets all boolean type variables spades, hearts diamonds and clubs to false initially
boolean spades = false;
boolean hearts = false;
boolean diamonds = false;
boolean clubs = false;
String[] deck = new String[4]; //to store card sequence
int index = 0; //to store index position
int NoOfPicks = 0; //to store number of picks (picks count)
while (!spades || !hearts || !diamonds || !clubs) { //loop starts
String card = printCard(getRandomCard()); //calls printCard method by passing getRandomCard method as argument to it to get the card
NoOfPicks++; //adds 1 to pick count
if (card.contains("Spades") && !spades) { //if that random card is a card of Spades and spades is not false
deck[index++] = card; //add that card to the index position of deck
spades = true; //sets spades to true
} else if (card.contains("Hearts") && !hearts) { //if that random card is a card of Hearts and hearts is not false
deck[index++] = card;
hearts = true; //sets hearts to true
} else if (card.contains("Diamond") && !diamonds) { //if that random card is a card of Diamond and diamonds is not false
deck[index++] = card;
diamonds = true; //sets diamonds to true
} else if (card.contains("Clubs") && !clubs) { if that random card is a card of Clubs and clubs is not false
deck[index++] = card;
clubs = true; } } //sets clubs to true
for (int i = 0; i < deck.length; i++) { //iterates through the deck i.e. card sequence array
System.out.println(deck[i]); } //prints the card number in deck
System.out.println("Number of picks: " + NoOfPicks); } //prints number of picks
public static int getRandomCard() { //gets random card
return (int) (Math.random() * 52); } //generates random numbers of 52 range
public static String printCard(int cardNo) { //displays rank number and suit
String[] suits = { "Spades", "Hearts", "Diamonds", "Clubs", }; //array of suits
String[] rankCards = { "Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10",
"Jack", "Queen", "King" }; //array of rank
int suitNo = cardNo / 13; //divides card number by 13 and stores to suitNo
int rankNo = cardNo % 13; //takes modulo of card number and 13 and store it to rankNo
return rankCards[rankNo] + " of " + suits[suitNo]; }} //returns rankCard at rankNo index and suits at suitNo index

Low level security is designed to detect and impede _____ some unauthorized external activity Some None Most All
Answer:
Low-level security is designed to detect and impede some unauthorized external activity.
Examples of low-level security systems include:
Basic physical obstacles to defense Locks for increased-security Simple lighting coverage Standard alarm SystemsExplanation
Protection devices that prevent and track any unwanted external actions are called Low-Level security measures.
Other obstacles to the installation of the security system, such as reinforced doors, fences, high-security locks, and window bars and grates, are often installed after simple physical protection barriers and locks have been created.
Also, a simple lighting system that could not be more complex than the standard security lighting systems over windows and doors and a regular security warning system that will be an unattended unit that offers monitoring capability and sound warnings at the location of unwanted entry.
Storage facilities, convenience shops, and small business premises are some of the locations that incorporate low-level security devices.

You have a large text file of people. Each person is represented by one line in the text file. The line starts with their ID number and after that, has the person's name. The lines are sorted by ID number in ascending order. There are n lines in this file. You write a search function that returns the name of a person whose ID number is given The simplest way to do that would be to program a loop that goes through each line and compares the ID number in the line against the given ID number. If there is a match, then it returns the name in that line. This is very inefficient, because the worst-case scenario is that this program needs to go through almost everyone the person we are looking for could be last. using the fact that he tli s sored wil greany speed up the processbus to use a birarysearch alkrhm We go to the middle line of the file first and compare the ID found there (P) to the given ID (Q). (f the number of lines is even, we go above or below the arithmetic middle.) if P=Q then our algorithm terminates . we have found the person we are looking for. If P is less than Q, that means that the person we are looking for is in the second half of the file. We now repeat our algorithm on the second half of the file. If P is greater than Q, that means that the person we are looking for is in the first half of the file. We now repeat our algorithm on the first half of the file.

g Unlike when you create a String, when you create a StringBuilder, you must use the keyword ____________.
Answer:
Unlike when you create a String, when you create a StringBuilder, you must use the keyword new
Explanation:
Strings are used in programming which also opens the way for StringBuilder to be used too. In javascript, for instance, variables are useful for storing data, We have "Let" and "const" variables. Const variables cannot be changed after they’re created. The data stored are in types an example is a string. Strings allow one to write a value and store the result in a variable.
For example, using the dot operator, when you:
console.log('love'.length); // Prints 4
Note that console.log() allows the computer to evaluate the expression inside the parentheses and print that result to the console.
.length prints 4 as the result. This shows how the string has a property that stores the number of characters in that string.
StringBuilder with the keyword "new" is used when we want to change or modify data property stored in a string.

Create an HTML form that will accept four fields: pet name, pet ID, pet weight, and birthdate. Name this file petInfo.html. There should be a submit and reset button on your html form. Your input fields for your form should be inside of a table. The submit button should send the data to a php file named updateInfo.php. The updateInfo.php file should check the data submitted by the html file for proper formatting. While it is allowable that you may check input on the client side (either HTML or Javascript), you MUST check for valid input on the server using PHP.
***IMPORTANT***
Your POST variables in your HTML file must be labeled as follows. I have written an automated script to run tests on your code, and it depends on the POST variables being labeled correctly within the HTML Form.
1) "pet_name"
2) "pet_id"
3) "pet_weight"
4) "birth_date"
The following rules must be enforced by your PHP script about the input.
• No field is allowed to be blank.
• Maximum length of pet name is 20 characters.
• Pet ID must be 4 lowercase letters followed by 3 numbers. Example: abcd123
• Max length of pet weight is 7 characters. Max of two digits after decimal point. Must be a positive value. Range: 0.00 – 9999.99.
• The name should be only made up of alphabetical characters. (no numbers or symbols).
• Birthdate should be in the format 1/1/2002. Examples of valid input: 01/01/2002, 12/1/1999, 12/25/2015. Do not allow: 12/25/02 (The whole year should appear in the input).
If all the fields are valid, your PHP script should save the data into a file named petInfo.txt which should have the following format, and be sorted by "pet_name". Put each record on its own line. To simplify things, you can assume that Names are unique - i.e. you can use the name as a key for your associative array. (I won't use two of the same name when I test your code).
PetName, PetID, PetWeight, PetBirthDate\n
Once the new data has been received, you should also display ALL data that has been entered into the text file from your PHP script into an HTML table. The table should be sorted by last name just like the text file. After successfully displaying your table, create a link back to the petInfo.html page.
