正整数n的阶乘是从n到1的所有值的乘积。例如,阶乘3是(3 * 2 * 1 = 6)。
1. Take integer variable A 2. Assign a value to the variable 3. From value, A up to 1 multiply each digit and store 4. The final stored value is factorial of A
import java.util.Scanner; public class Factorial { public static void main(String args[]){ int i, factorial=1, number; System.out.println("输入您需要查找阶乘的数字:"); Scanner sc = new Scanner(System.in); number = sc.nextInt(); for(i = 1; i<=number; i++) { factorial = factorial * i; } System.out.println("Factorial of the given number is:: "+factorial); } }
输出结果
输入您需要查找阶乘的数字: 25 Factorial of the given number is:: 2076180480
