If a function does not return a value, which of the follow is correct?Group of answer choicesThe return type is a Swift optional type.The return type must be set to nil.The return type is omitted from the function declaration.

Answers

Answer 1

Answer:

In swift programming language it is ok when a function does not return any value you are not necessarily required to set return type because it is optional so the correct answer is  "The return type is omitted from the function declaration".

Explanation:

If programing language is swift so we can omit return type from function declaration otherwise if language is C++ we can set return type "Void".

The concept of boolean variables is that; variables declared as boolean type can only take any of two values. The variable can either be true or false. Such variable cannot take any other value apart from these two.

The short quiz program is as follows.

Please note that comments are used to explain difficult lines.

import java.util.*;

public class shortQuiz{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

//This declares the variables that represent correct answers as boolean data type; the variables are also initialized

 boolean q1 = true, q2 = false, q3 = true;

//This declares the response to each question as boolean data type

 boolean q1response, q2response, q3response;

//This prints the first question

 System.out.print("Java is a programming language, true or false? ");

//This gets input for the first response

 q1response = input.nextBoolean();

//This prints the second question

 System.out.print("Only numbers can be stored by variables in Java, true or false? ");

//This gets input for the second response

 q2response = input.nextBoolean();

//This prints the third question

 System.out.print("There are only 2 possible values which can be held by a boolean variable, true or false? ");

//This gets input for the third response

 q3response = input.nextBoolean();

//This prints your first response, alongside the correct answer to the first question

 System.out.println("Question 1 - Your answer: "+q1response+". Correct answer: "+q1);

//This prints your second response, alongside the correct answer to the second question

 System.out.println("Question 2 - Your answer: "+q2response+". Correct answer: "+q2);

//This prints your third response, alongside the correct answer to the third question

 System.out.println("Question 3 - Your answer: "+q3response+". Correct answer: "+q3);

//The program ends here

}

}

g Unlike when you create a String, when you create a StringBuilder, you must use the keyword ____________.

Answers

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.

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

Answers

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.

In #1 A can pass legally, in #2 B can pass legally, and in #3 neither can pass legally.

The Goal: Similar to the first project, this project also uses the random module in Python. The program will first randomly generate a number unknown to the user. The user needs to guess what that number is. (In other words, the user needs to be able to input information.) If the user’s guess is wrong, the program should return some sort of indication as to how wrong (e.g. The number is too high or too low). If the user guesses correctly, a positive indication should appear. You’ll need functions to check if the user input is an actual number, to see the difference between the inputted number and the randomly generated numbers, and to then compare the numbers.• Concepts to keep in mind: • Random function• Variables• Integers• Input/Output• Print• While loops• If/Else statements

Answers

Answer:

Here is the Python program:

import random #to generate random numbers

def generateRandNo(): #function to generate random number

    randNo = random.randint(1,100) #generates random number in range from 1 to 100

    return randNo #returns the generated random number

   

def userInput(message = "Guess the number "): #to gets integer input from user and return the input number

    userGuess = int(input(message)) #store the int type input from user in userGuess variable

    return userGuess #returns the user input number

   

def compareNumbers(userGuess,randNo): #compares the user input with actual randomly generated number

    if userGuess > randNo: # if user input is greater than actual number

         return "The number is too high"

    elif userGuess < randNo: #if user input is less than actual number

         return "The number is too low"

    else: #if user guess is correct

         return "Correct"

def main(): #main method

    correct = False #sets correct to False

    begin = True #sets start game i.e. begin to True

    while correct or begin: #while loop keeps repeating as long as user guess is correct or user wants to start game again

         guessCount = 0  #counts number of trials user takes to guess the correct number

         randNo = generateRandNo() #generates a random number using generateRandNo

         userGuess = userInput() #gets input number from user using userInput method

         guessCount+=1 #increments at each guess made by user

         message = compareNumbers(userGuess,randNo) #compares user guess input number with actual number

         

         while message != "Correct" : # while message is not equal to Correct

              print(message) #prints to guess the number

              userGuess = userInput("Try again: ") #keeps asking user to try again and enter a number

              guessCount = guessCount + 1 #increments guessCount  by 1 at each guess made by user

              message = compareNumbers(userGuess,randNo) #compares user input with actual number

         print()

         print(message,"It took you ",guessCount," attempts to answer\n") #prints how much trials user took to guess correct number

         choice = input("Do you wish to continue? (Enter yes or no) ") #asks user if user wants to start over

         if choice == 'no': # if user enters no

              exit(1) #exits the program

         else: #if user enters yes starts the game again

              correct = True #sets correct guess to True

main() #calls main method to start the guess game

Explanation:

The program is well explained in the comments attached with each line of the code. Suppose the randomly generated number (actual number) is 50 and user input is 24  then message The number is too low is displayed and if user guess input is 80 then The number is too high is displayed. If the user guesses the correct number i.e. 50 3rd time then the message displayed is:

It took you 3 attempts to answer.

The the user is asked to continue as:

Do you wish to continue? (Enter yes or no)

If user enters no the program exits if yes then user is asked to Guess the number again.

Explanation:

In the above given C++ language modified code, four-string variable " name, address, MSG_YES, and MSG_NO", four integer variable "item, quantity, size, and i", and "integer and double" array is defined, that holds values.

In the string and integer variable "name, address, and item, quantity", we input value from the user-end and use the while loop, which uses the if block to check the "item and quantity" value from the user end and print its respective value.

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.

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.
