C编程：输入1--7七个数，判别并说出它对应的是一个星期的哪一天

int main()
{
int wday;
scanf("%d", &wday);
switch(wday)
{
case 1: printf("星期一"); break;
case 2: printf("星期二"); break;
case 3: printf("星期三"); break;
case 4: printf("星期四"); break;
case 5: printf("星期五"); break;
case 6: printf("星期六"); break;
case 7: printf("星期日"); break;
default: printf("输入数据错");
}

}

#include <stdio.h>
void main()
{
int day;
printf("Please input a number:");
scanf("%d",&day);
switch(day)
{
case 1: printf("Monday\n");break;
case 2: printf("Tuesday\n");break;
case 3: printf("Wednesday\n");break;
case 4: printf("Thursday\n");break;
case 5: printf("Friday\n");break;
