5-2 PROJECT 1 FLOW CHART PORTION

A semicolon (;) is necessary at the end of which type of the loop?       All loops     do-while       while     for

What is the number of times the following loop is executed? for the value of b in (1,10): a printout of b

Create a class name AddAgain for do-while loop that asks the user to enter two The numbers should be added and the sum displayed. The loop should ask the user whether he or she wishes to perform the operation again. If so, the loop should repeat; otherwise it should terminate.

option 3 is incorrect

Question #3: Write a program that asks the user to enter an integer number and checks whether the number is prime or not. Hint: A prime number (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37...) is a natural number greater than I that has no positive divisors other than 1 and itself. To check if a number N is prime, divide it in a loop from 2 to N-1 for remainder. If remainder is never 0, then N is prime. For example, 23 and 47 are prime, but 12 and 27 are not.

Write a for loop that repeats seven times, asking the user to enter a number. The loop should also calculate the sum of the numbers entered and display the final sum.       Write a for loop that displays the following set of numbers:       0, 10, 20, 30, 40, 50 . . . 1000 What’s the initialization step? The Boolean test/condition? Update action/incrementation?     Convert the while loop in the following code segment to a for loop: int count = 0; while (count < 50) { System.out.println("count is " + count); count++; } please solve three of them

Make a Craps game with the following guidelines: import random money = 100 Ask user if they want to play or "QUIT" (.upper()) while game !="QUIT": 2 dice generate random numbers 1-6 on each (generate random numbers inside while loop) Every roll cost $3 Win $5 if total is7 Win $10 for snake eyes Else display " Craps" Ask user if they want to play or"QUIT" if money<3 game ="QUIT" Print money

Write a loop that runs 10 times.  Note: You are not required to put anything inside the loop body.

Control Loops: A high school 1000 students and 1000 lockers. The principal plays the following game: She asks dthe first student to open all the lockers. Shen then asks the second student to close all the even-numbered lockers. The third student is asked to check every third locker. If it is open, the student closes it; if it is closed, the student opens it. The remaining students continue this game . In general, the nth student  checks every nth locker. If the locker is open, the student closes it; if it is closed, the student opens it. After all the students have taken their turns, some of the lockers are open and some are closed. Write a program thatprompts the user to enter the number of lockers in a school. After the game is over, the program outputs the number of lockers  and the locker numbers of the lockers that are open. Test run your program for the following inputs: 1000, 5000, 10,000. Do you see any pattern developing for the locker numbers that are open in the output?…

Question #3: Write a program that asks the user to enter an integer number and checks whether the number is prime or not. Hint: A prime number (2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37 . .) is a natural number greater than 1 that has no positive divisors other than 1 and itself. To check if a number N is prime, divide it in a loop from 2 to N-1 for remainder. If remainder is never 0, then N is prime. For example, 23 and 47 are prime, but 12 and 27 are not. Question #4: Re-write the program of Question #3 using data files. The input data numbers.txt contains (positive) integer numbers. Each time the program reads a number, check whether it is a prime and stores the result in the output file Results.txt. 373 373 is Prime!! 11 is Prime!! 2552 is NOT prime!! 5 is Prime!! 3561 is NOT prime!! 11 2552 3561 numbers.txt Results.txt End of Homework #2 ==== Page 7 of 7

Loop that will allow for one complete round of hangman and if the word is guessed correct letter by letter the gallows shows the hangman

You need to write a loop that will repeat exactly 125 times. Which is the preferred loop construct to use?   A. while   B. do while loop   C. for loop

Part A:  While Loop Program - using Java. Write a program that detects Fibonacci numbers.  Prompt the user to input a positive integer.  Upon input, the program will determine if the number is either a Fibonacci number or not.  If a Fibonacci number, then the order of the number in the sequence must be output.  If not a Fibonacci number, then the Fibonacci numbers above and below it (including their order in the sequence) must be output.  Once it finishes, the program will prompt the user for a new number.  The program will exit if the user enters a non-integer number or string (such as “quit”) instead of an integer.  Use the sample output file, fib-seq-det.txt, to view a sample session   Additionally: For both the above problems, the first four numbers of the Fibonacci sequence are: 0, 1, 1, and 2. Part A must use While loops only

Question#2. The distance a vehicle travels can be calculated as fallout: Distance = Speed * Time For example, if a train travels 60 miles-per-hour for three hours, the distance [raveled is 120 miles. Write a program that asks for the speed of a vehicle (in miles-per-hour) and the number of hours it has traveled. It should use a loop to display the distance a vehicle has traveled for each hour of a time period specified by the user. For example, if a vehicle is traveling at 40 mph far a three-hour time period, it should display a report similar to the one chat follows: Hour Distance Traveled 1 90 2 100 3 150 Input Validation: Do not accept a negative number for speed and do not accept any value les than 1 for time traveled.

Q2: Write a program that reads in a series of integer numbers, and determines how many positive odd numbers are among them. Numbers are read until a negative integer is given. Use DO-Loop with EXIT statement.
