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
