1. Find factorial using Loop# Code to find factorial on num # number num = 4 # 'fact' - variable to store factorial fact = 1 # run loop from 1 to num # multiply the numbers from 1 to num # and, assign it to fact variable for i in range(1, num + 1): fact = fact * i ...
In the following PHP program factorial of number 5 is calculated. This is a simple program using for loop. This for loop is iterated on the sequence of numbers starting from the number till 1 is reached. Code: <?php //example to calculate factorial of a number using simple for loop //...
Note: To test the program for a different number, change the value of num. Here, the number whose factorial is to be found is stored in num, and we check if the number is negative, zero or positive using if...elif...else statement. If the number is positive, we use for loop and...
let mut result = 1;: This line declares a mutable variable 'result' and initializes it with the value 1. for i in 1..=n { ... }: This line starts a "for" loop. The loop iterates from 1 to 'n' (inclusive) and for each iteration, the current value of i is multiplied with ...
Solution 1: Factorial Calculation using Loops Code: import java.util.Scanner; public class FactorialUsingLoop { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); // Taking user input System.out.print("Enter a number: "); ...
