哪位大侠用c编下面这个程序：从键盘输入1～7（否则应给出出错信息）之间的数字,输出表示一个星期中对应某一天的英文单词.

#include
#define DAYS_OF_WEEK 7
char *day[DAYS_OF_WEEK] =
{
"monday",
"tuesday",
"wendsday",
"thirsday",
"friday",
"saturday",
"sunday"
};
int main(void)
{
int i;
scanf("%d",&i);
if (i < 1 || i > DAYS_OF_WEEK)
{
printf("You've entered a wrong day\n");
return -1;
}
printf("The day is %s\n",day[i-1]);
return 0;
}
