The factorial of n (written n!) is the product of the integers between 1 and n. Thus 4! = 1*2*3*4 = 24. By definition, 0! = 1. Factorial is not defined for negative numbers. 1. Write a program that asks the user for a non-negative integer and computes and prints the factorial of that integer. You'll need a while loop to do most of the work-this is a lot like computing a sum, but it's a product instead. And you'll need to think about what should happen if the user enters 0. 2. Now modify your program so that it checks to see if the user entered a negative number. If so, the program should print a message saying that a nonnegative number is required and ask the user the enter another number.

Concept explainers

Types of Loop

Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.

Loops

Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.

While Loop

Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

Question

Factorials
The factorial of n (written n!) is the product of the integers between 1 and n. Thus 4! = 1*2*3*4 = 24. By definition, 0! = 1.
Factorial is not defined for negative numbers.
Write a program that asks the user for a non-negative integer and computes and prints the factorial of that integer. You'll
need a while loop to do most of the work-this is a lot like computing a sum, but it's a product instead. And you'll need
to think about what should happen if the user enters 0.
1.
2. Now modify your program so that it checks to see if the user entered a negative number. If so, the program should print a
message saying that a nonnegative number is required and ask the user the enter another number. The program should
keep doing this until the user enters a nonnegative number, after which it should compute the factorial of that number.
Hint: you will need another while loop before the loop that computes the factorial. You should not need to change any
of the code that computes the factorial!

What is the solution of this problem (using java language)?
I am trying to make a while loop that checks for a condition from user input. If the user inputs anything except for valid integers, the while loop requires the user to reenter until a valid integer is input. I have tested this code, but the while loop isn't overwriting the maxNotNumber variable when reentered. Please tell me what I'm doing wrong. let min = 1; //minimum number let score = 0; let max = Math.ceil(prompt("Enter a maximum number 1 or greater for the guessing game."));//asks for user's max number input and rounds any decimals up maxNotNumber = Number.isInteger(max);//checks for nonnumbers console.log(maxNotNumber); //initial user max number input let random = Math.ceil(Math.random() * (max - min) + min); console.log(random); //randomly generated number between 1 and user max while (maxNotNumber != true) {//Illegal number check maxNotNumber = Number.isInteger(max);//checks for nonnumbers max = prompt("That's not a number. Try again."); console.log("This is from the…
Write a program that uses a for loop to display a table that lists in one column values for ounces, followed by columns that show the equivalent in pints, quarts and litres: Enter a start value, an end value and a step value for a range of values for the ounces. • Use a for loop to do the following for the range values: • Show on each line of the table four columns starting with the ounces, followed by the pints, quarts and litres. The formulas for the units are: • pints: ounces * 0.0625 • quarts: ounces * 0.03125 • litres: ounces * 0.02957 • Show all values in the table with two decimal places each, and right-aligned so all the decimal places are lined up with one another. Use a while loop to show the table. • Show the table from a high value to a low value.
Write a program that asks a user to input the height of triangle and draw a triangle that has the following pattern. Use nested loops for this problem. If the user enter height as 4 Then the triangle output is 1 1 2 1 2 3 1 2 3 4 We make the following assumptions • There is no space between the margin and first number in each row • There could be a space after the last number on every line • There is pne space between numbers on every line • There maybe a newline at the end of last line There is one test-case to check your code, there are two hidden testcases that tests correctness of your code 376584 2469
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.
Write a program that receives an integer input from the user and call it n. Use a for loop, an if condition, and a continue keyword, to find the summation of all numbers that are not a multiple of 3, from 1 to n, including 1 and n and print the result. For instance, the output of your program for 9, should be 27 and for 17 should be 108. You can get an input from user and convert it to an integer using a = int(input('Please enter an integer:')).
Factorial of a number n is denoted as n! And the value of n! Is: 1*2*3... (n-1)*n. Create Java Program to find factorial of a positive integer number using the following Loops: a. for Loop b. while loop Valid input is less than or equal to 15 (Input <= 15) only, otherwise the input is Invalid. Please see the attached image for the Output format. Please don't answer my question if you don't read the instructions carefully, this is my last question so please cooperate.
JAVA A perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. A divisor of an integer x is an integer that can divide x evenly. Take an integer n as input from the keyboard, print true if n is a perfect number, otherwise, print false. You do not need to print any explanation, just print true or false. Use a for loop to generate the divisors. Example 1: Input: num = 28 Output: true Explanation: 28 = 1 + 2 + 4 + 7 + 14 1, 2, 4, 7, and 14 are all divisors of 28. Example 2: Input: num = 6 Output: true Example 3: Input: num = 496 Output: true Example 4: Input: num = 8128 Output: true Example 5: Input: num = 2 Output: false
hello...Its not correct...
Question 2: Write a program to read student ID and check whether it is odd/even number. Output a 4X4 badge if the student ID is even number and output a 3X3 badge if it is odd number. The badge is built up by the (height X width) of asterisks. (Use for-loop to draw the asterisks, do not hard-coded)
I am having an issue with this program, I keep getting the number 15 everytime I type in a code. There is also the instructions for the module itself. //PSEUDOCODE //Write a program that prompts the user for a binary number //(from 3 to 8 bits) as a String and converts it to base-10 decimal value //There are several ways to do this in Java but your program must use a for loop and first principles to perform the conversion //Print the base-10 number when the loop ends public static void main(String args[]) { long sum = 0; System.out.println("Enter a binary number: "); Scanner scan = new Scanner(System.in); String s = scan.next(); long result = 0; for (int i = 0; i < s.length(); i++) { result = (long) (result + (s.charAt(1) - '0') * Math.pow(2, s.length()- i - 1)); scan.close(); } System.out.println(result); }}
JAVA Write a java program that takes a string as input from the user and finds out if the string is a palindrome or not. A string is a palindrome if it reads the same from forward as well as from backward. For example, the string “madam” is a palindrome. Use a for loop to solve this problem. Sample inputs and outputs: Input: madam Output: palindrome Input: Dad Output: palindrome Input: hello Output: not a palindrome
