       Several summers ago, Joe Smith, the coach of a football team, and his family were spending their

holiday in a small town. One rainy afternoon, it was impossible for them to go out to do anything

interesting, so the family decided to go to the cinema. Joe, his wife and their children walked down to the

town’s only cinema, bought tickets and went into the hall. The lights were still on, and there were just six other people there. As Joe entered, some of them saw him and started clapping (鼓掌).    

       Joe gave them a smile and turned to his wife. “Aha, I can’t believe they know me and I’m getting a warm welcome here,” he said, “I guess they saw my games on TV.”    

       They sat down and then a young man came over and reached out his hand to shake hands with Joe. “Thanks a lot,” replied the coach, “I just can’t believe you know who I am.” The man looked

puzzled (困惑的). “All I know,” replied the man, “is that they would not show the film until at least

ten people bought tickets.”

以下是某C程序段，其功能为计算输入数字的阶乘。请仔细阅读程序并完成要求。
#include＜stdio. h＞
#include＜stdlib. h＞
int main()

int i=0；/*i为计数器*/
int n；
int factorial=1；/*保存阶乘的结果*/
puts("*************************************")：
puts("*The program will compute *")；
puts("*the factotial of an integer *")；
puts("*************************************")：
puts("please input the number n：")；
scanf("%d"，＆n)；
if(n＜0)/*判断输入的数是否大于或等于0*/

printf("please input an interger>=0. \n")；
return 0；

if(n==0)/*0的阶乘是1*/

printf("factorial of 0 is 1.\n")；
return 0；

i=1；
while(i＜=n)

factorial = factorial * i；
i++：

printf("factorial of % d is：%d. \n"，n，factorial)；
getch()；
return 0：

设计一组测试用例，使该程序所有函数的语句覆盖率和分支覆盖率均能达到100%。如果认为该程序的语句或分支覆盖率无法达到100%，需说明为理由。
