Factorial
program in C#
Factorial Program in C#: Factorial of n is the product of all positive descending integers. Factorial of n is denoted by n!. For example:
|
4! = 4*3*2*1 = 24 6! = 6*5*4*3*2*1 = 720 |
|
private static void
Factorial() { int i,
fact = 1, number;
Console.Write("Enter any Number: ");
number = int.Parse(Console.ReadLine()); for (i =
1; i <= number; i++) {
fact = fact * i; }
Console.Write("Factorial of " +
number + " is: " + fact); } |
Factorial using recursive function
|
static void Main(string[]
args) {
Console.Write("Enter a Number : "); int
number = int.Parse(Console.ReadLine()); long
factorial = RecursiveFactorial(number);
Console.Write($"Factorial of {number} is:
{factorial}");
Console.ReadLine(); } static long
RecursiveFactorial(int number) { if
(number == 1) { return 1; } else { return
number * RecursiveFactorial(number - 1); } } |
