Write a JavaScript function named testGrade() that is able to do the following tasks: • First, pop up a prompt dialog box to ask the user to enter a test mark. • Use a while-loop to verify the user input. If the input value is less than 0 or more than 100, a prompt dialog box will pop up to ask user re-enters the test mark. This prompt dialog will keep popping until the user enters a valid test mark. • If the mark entered by the user is more than 70, an alert dialog box will be prompted with the message “Pass!”, otherwise an alert dialog box will be prompted with the message “Fail!”.

in javascript please create a function that does the following and is named as such please don't copy and paste the incorrect answer sequence( start, step ) This function takes two numeric inputs, start and step, and returns a function of no inputs. The ith invocation of the resulting function will generate the value: start + step * i. The first invocation is said to be the 0th. Examples var x = sequence( 3, 15 ) [ x(), x(), x() ] => [ 3, 18, 33 ] var y = sequence( 28, -5 ) [ y(), y(), y() ] => [ 28, 23, 18 ]
Write a program whose input is two integers and whose output is the two integers swapped. Ex: If the input is: 3 8 the output is: 8 3 Your program must define and call the following function. swap_values() returns the two values in swapped order.def swap_values(user_val1, user_val2) this is what I have but its not letting mt pick random numbers : def swap_values(user_val1, user_val2):#Create a temporary variable to swap the valuestemp = user_val1user_val1 = user_val2user_val2 = tempreturn user_val1,user_val2 # Take inputs from the useruser_val1 = int(input())user_val2 = int(input())x,y = swap_values(user_val1,user_val2) print(x + ' ' + y) I need the numbers to be side by side once they are answered.
Write a program in Python for a (very) rudimentary shooter "game". You are the only shooter and you start with ammo of 10. The one enemy doesn't shoot back and starts with health of 5. Code a custom function named shoot that prints "Shot fired" and returns True for a hit or False for a miss. Generate a random 0 to assign False or 1 to assign True. In the main function, use a while loop that runs the shoot function until you run out of ammo, at which point you lose. Report both hits and misses (see Sample Outputs). If your shot is a hit as determined by the value returned by shoot, your code should lower the enemy's health. If you are lucky, the health of the enemy will be reduced to zero before you run out of ammo. If this happens, report the enemy's demise and use the break keyword to stop the loop. You have won.

Your task is to implement a variation of the classic word game Hangman, which involves players guessing the letters in a word chosen at random with a finite number of guesses. While there are alternate versions such as category Hangman and Wheel of Fortune, which involve players guessing idioms, places, names and so on, we will be sticking with the traditional version. Requirements:You will implement a function called main that allows users to play an interactive hangman game against the computer. The computer should pick a word, and players should then try to guess letters in the word until they win or run out of guesses.Here is the overarching behaviour we expect:1. The program should load a list of available words from the text file provided. Note that the file you have been given contains words in lowercase.2. The computer should then select a word at random from the list at random.3. The user is given a certain number of guesses at the beginning.4. The game is interactive; the…
Q2: Write a JavaScript function that accepts a number from a user as input and checks if the number is prime, then print True if the number is not a prime, print False. Note: A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself.
Python question, please us a docstring and have comments throughout code Write a function getInteger() that takes two integers num1 and num2 as parameters. If num1 > num2, then the function prints an error message and returns 0. If num1 is equal to num2, the function returns the common value. For cases where num1 < num2, the function prompts the user to enter an integer greater than or equal to num1 and less than or equal to num2 and returns the first valid integer that the user enters. If the user enters something that is not an integer value, the programs should display an error message and re-prompt the user to enter a valid integer Below are some sample executions of the function. Use the while and if-elif statements and a try/except in the solution. Don’t forget to include the docstring and comments. Copy and paste or screen shot the code and the thirteen test cases shown below in your submission. . >>> getInteger(5,4) 5 and 4 are not valid parameters 0…

Write a python program that has a main() function and a value returning function named numbers() that takes no arguments and returns the variable used for the total. The numbers function generates 18 random integers, it is required you use the random.randint method to generate these numbers as the unitTest requires this. The range would be 7 to 61 inclusive, (duplicates are okay), and prints them all on one line separated by spaces. A loop is required for this, and the loop should also total up the integers so the sum can be displayed when the loop ends. The main() function calls the numbers() function which prints the random numbers and the total as shown below. Do not forget that numbers() function must return variable containing total that was printed. Output should look like this: 33 59 57 44 12 49 48 18 44 51 8 51 51 50 59 53 61 19 The total is 767
Write a simple JavaScript program to calculate the average mark and to calculate the grade of a student. Pass the rest parameter prefixed with three dots (...) as an argument to implement the function calculateAverageMark() - calculateAverageMark(...args)Calculate the average mark of the student and return it. Then, this average is used to determine the corresponding grade. Return the output with 2 decimal places. Implement the calculateStudentGrade() function to calculate the student grade based on the average mark.The average mark returned by the function calculateAverageMark() is passed as argument to this function.The grades are computed as follows: Range Grade <50 F <60 D <70 C <80 B <90 A <100 O Note: You may verify the correctness of your function by invoking it from within console.log as shown in sample input and output Sample Input and Output:Sample Input1:console.log(calculateAverageMark(80, 77, 88, 95,…
python Write a program that does temperature converter", "- The user will enter if he wants the result in Celsius or in Fahrenheit. Use the input function to read this option. \n", "- Ask the user the value of the temperature he wants to convert. Use the input function to read this value and convert accordingly.\n", "- If the user wants the temperature in Fahrenheit compute: $ Fahrenheit = Celsius5/9+32$.\n", "- If the user wants the Celsius compute as follows: $ C = (F-32)5/9 $.\n", "\n", "Print the converted temperature and show the unit, like 23.5 C or 67.1 F."
I). Write a program in c++ with class that will help an elementary school student learn multiplication. Use the rand function to produce two positive one-digit integers. The program should then prompt the user with a question, such as How much is 6 times 7? The student then inputs the answer. Next, the program checks the student’s answer. If it’s correct, display the message "Very good!" and ask another multiplication question. If the answer is wrong, display the message "No. Please try again." and let the student try the same question repeatedly until the student finally gets it right. A separate function should be used to generate each new question. This function should be called once when the application begins execution and each time the user answers the question correctly.
