To find the Python factorial of a number, the number is multiplied with all the integers that lie between 1 and the number itself. Mathematically, it is represented by “!”. Thus, for example, 5! will be 5 x 4 x 3 x 2 x 1, that is 120. Factorial for negative numbers is not ...
Scala – Find the Factorial of a Number Factorial Factorial of a number(n!)is the product of all positive numbers less than or equal to that number. The formula for factorial of a number is, n! = n * (n-1) * (n-2) * ... * 2 * 1 n! = 1 if n = 1 or 0 ...

Factorial Using a Recursive Program The following program demonstrates a recursive program to find the factorial of a number. Example Live Demo #include <iostream> using namespace std; int fact(int n) { if ((n==0)||(n==1)) return 1; else return n*fact(n-1); } int main() { ...
In this program, the user is asked to enter a positive integer. Then the factorial of that number is computed and displayed on the screen. Example: Find the Factorial of a Given Number #include <iostream> using namespace std; int main() { int n; long factorial = 1.0; cout << "Enter...
Here's the equivalent Java code: Java Program to Find Factorial of a Number. Example 2: Find Factorial of a number using BigInteger import java.math.BigInteger fun main(args: Array<String>) { val num = 30 var factorial = BigInteger.ONE for (i in 1..num) { // factorial = factorial ...
cout << " === Program to find the Factorial of a given number === \n\n"; //variable declaration int i,n; //as we are dealing with the product, it should be initialized with 1. int factorial=1; //taking input from the command line (user) cout <...
