我们都知道如何计算一个数的阶乘,可是,如果这个数很大呢,该如何计算? 当一个数很大时,利用平常的方法是求不出来它的阶乘的,因为数据超出了范围.因此我们要用数组来求一个大数的阶乘,用数组的每位表示结果的每个位数.话不多说,直接上代码 #include<stdio.h> #include<string.h> int main() { int i,j,n,temp,d=1,carry;//temp为阶乘元素与临时结果的乘积,carry是进位 ,d是位数 int a[3000];//确保数…

循环从1乘到20,要注意的就是结果可能会很大,长度超出int类型的范围,所以定义乘积的时候用long. 代码如下: public class Practice3 { public static void main(String args[]){ long result=1; for(int i=1;i<=20;i++) result=result*i; System.out.println("20的阶乘为"+result); } } 效果如图:…
