请编写函数fun()，它的功能是计算下列级数和，和值由函数值返回。
S=1－x＋x2(上标)/2!－x3(上标)/3!＋…＋ (-1*x) n(上标)/n!
例如，当n=15，x=0.5时，函数值为0.606531。
注意：部分源程序给出如下。
请勿改动主函数main和其他函数中的任何内容，仅在函数fun的花括号中填入所编写的若干语句。
试题程序：
include＜conio.h＞
include＜stdio.h＞
include＜math.h＞
double fun(double x, int n)
{
}
main()
{
clrscr();
printf("%f ",fun (0.5,15));
}

OSPF协议要求所有的区域都连接到OSPF主干区域0，当一个区域和OSPF主干区域0的网络之间不存在物理连接或创建物理连接代价过高时，可以通过创建OSPF虚链路(virtual link) 的方式完成断开区域和主干区域的互连。在该公司的网络中，区域3和区域0之间也需要通过虚拟链路方式进行连接，请给出路由器R3和路由器R8上的 OSPF进程配置信息。

S. government, therefore, supported the South Vietnamese government./This government' s policies led to rebellion in the South./Finally, however, the United States failed to achieve its goal,/and in 1975 Vietnam was reunified under Communist control;/in 1976 it officially became the Socialist Republic of Vietnam./
