#include <stdio.h>
main()
{
int n;
do
{
printf("please input a odd number.\n");
scanf("%d",&n);
}while((n>15)||(n<3)||(n%2==0));
getch();
}


以上程序，当我输入非数字的字符时，结果是执行无限循环的printf("please input a odd number.\n");根本不再做scanf的动作，为什么？

I found the answer myself.
reason:
The next character read can't be converted under the current format (for example, an A when the format is decimal).
