Project 14: Class scores Write a program that calculates the total grade for N classroom exercises as a percentage. The user should input the value for N followed by eachof the N scores and totals. Calculate the overall percentage (sum of the total points earned divided by the total points possible) and output it as a percentage.SAMPLE RUN #1: ./ETestInteractive SessionHide InvisiblesEnter the number of exercises to input:.4.4#Enter the score received for Exercise 1: 6..Enter the total points possible for Exercise 1: 20...Enter the score received for Exercise.2: -6.4Enter the total points possible for Exercise-2:-30.4Enter the score received for Exercise. 3:.18...Enter the total points possible for Exercise. 3:.30..Enter the score received for.

A for statement is a loop that goes through a list of things. Therefore, it keeps running as long as there are objects to process. Is this a true or a false statement?
Count of Guess Create a JAVA program to generate a random number in the range [1,10] and then prompt the user to guess a number until the user guesses the correct random number generated. The program should print the number of attempts in which the user enters the correct number.
Chapter 4 Loops and Files 17. Random Number Guessing Game Write a program that generates a random number and asks the user to guess what the num- ber is. If the user's guess is higher than the random number, the program should display "Too high, try again." If the user's guess is lower than the random number, the program should display "Too low, try again." The program should use a loop that repeats until the user cor rectly guesses the random number.
Add Fractions problem: create in a sandbox environment. Directions: In this program you will ask the user for 4 integers that represtent two fractions. First ask for the numerator of the first and then the denominator. Then ask for the numerator and denominator of the second. Your program should add the two fractions and print out the result. For example: a sample program run might look like this, Numerator One: 1 Denominator One: 2 Numerator Two: 2 Denominator Two: 5 The sum is 9/10 //remember if you have two fractions, the following formula should be used: a/b + c/d = (a*d +b*c) / b* d public class MyProgram { public static void main(String[] args) { //Ask the user for 4 numbers. (don't forget to import your Scanner class) //create your final numerator //create your final denominator //print out your result like the example above
program4_2.pyWrite a program that uses a while loop to enable the user to enter any number of positive integers. The loop should end when a sentinel value of 0 (zero) is entered. The program should then report the sum of the even integers and the sum of the odd integers.
True or False: When asking user for data, we can always turn an algorithm that uses a user-confirmation loop into one that uses a sentinel loop. Select one: a. False b. True
START Declare variables: evenCount = 0 oddCount = 0 continueProgram = true WHILE continueProgram = true Display "How many random numbers to generate?" Input quantity Set counter = 1 WHILE counter <= quantity Set randomNumber = Random number between 1 and 500 IF randomNumber % 2 = 0 THEN Set evenCount = evenCount + 1 ELSE Set oddCount = oddCount + 1 END IF Set counter = counter + 1 END WHILE Display "Total even numbers: " + evenCount Display "Total odd numbers: " + oddCount Display "Do you want to generate another set of random numbers? (yes/no)" Input response IF response = "no" THEN Set continueProgram = false END IF END WHILE Display "Program ended."END convert the code to Flowgorithm chart
Overview: Create a coin flip game that allows the user to guess whether the coin will be heads or tails. Save the data associated with the flip. Repeat for a total of 10 guesses/flips. Display result summary and details at end. Technical Requirements: Participant will guess whether a coin flip will result in Heads or Tails Computer will "flip" a coin to determine the side it lands using random generator import random at top of program result = random.randint(x,x) The program will display the results: Guess, Flip, Outcome (Match or No Match) The program will track the results and, when the game is over, display: Summary Detailed result of each turn Use parallel arrays to collect details from each turn that can be displayed as a table when the game is over Use running totals of each result detail to display at end
LAB: Loops: Output range with increment of 10 Write a program that reads two integers as input, and outputs the first integer and subsequent increments of 10 as long as the value is less than or equal to the second integer. Ex: If the input is: -15 30 the output is: -15 -5 5 15 25 Ex: If the second integer is less than the first as in: 20 5 the output is: Second integer can't be less than the first. For coding simplicity, output a space after every integer, including the last.
