Question

#include"stdio.h"
int main()
{
int a,b,n;
while(scanf("%d",&n)!=EOF)
{
b=1;
while(n<=0||n>12)
{
printf("shuruwuxiao!\n");
scanf("%d",&n);
}
for(a=1;a<=n;a++)b=b*a;
printf("%d\n",b);
}
return 0;
}
Description计算一个正整数(小于等于12)的阶乘Input任意一个正整数N（N <= 12）Output求出其阶乘
Sample Input
3
5
-5
Sample Output
6
120
shuruwuxiao!

Answer 1

while(n<=0||n>12)
{
printf("shuruwuxiao!\n");
scanf("%d",&n);
}
最好把这里改了
if(n<=0||n>12)
{
printf("shuruwuxiao!\n");
continue;
}

Answer 2

把循环内的 while改成
if(n<=0||n>12)
{
printf("shuruwuxiao!\n");
continue;
}
