求大神教我while(scanf("%d",&n)!=EOF)顺便教一下while(~scanf("%d",&n))

Question

#include
int main(void)
{
int max,n,i,s[100];
i=0;
while(scanf("%d",&s[i])!=EOF){
i++;
}
printf("%d",s[2]);
return 0;

}

Answer 1

while(scanf("%d",&n)!=EOF)
如果用户按下ctrl+z，那么停止输入

while(~scanf("%d",&n))
如果输入中的内容不能识别为整数，或者输入内容不足，scanf返回0
