用C语言编程 ：输入一个正整数n 用3种方法分别计算下式的和 保留4位小数

/
printf(", total).4f\ i <
for (j = i;= n;/
total += temp;= n;
double total = 0.h"
double total = 0:%:%;;= n;嵌套循环, temp = 1.0, total); j >.0; i <.0;
total = total + temp.0; i;;

/%d" j, &n); j--)
temp = temp / i++)
{
temp = temp /
}

return total;

double fact(int n)
{
int i.0;= 1;n"
}

int main(void)
{
int i; i++)
{
temp = 1, temp = 1; i <;
for (i = 1;调用函数
total = 0.4f\.0;嵌套循环
total = 0;

scanf(", fact(n));/

// i, n;调用函数;n".4f\一重循环
for (i = 1:%; i++)
{
temp = temp /一重循环;, j;
total = total + temp;
for (i = 1#include "
