C，跪求，编程，用每周的英文名称初始化一个字符指针数组，当键盘输入整数为1到7时，显示相应的周几，

#include<stdio.h>
void main()
{

char *day[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};/*这是个指针数组，其中每一个元素都相当于一个指针变量，指向字符串的首字母，这种用法很常用，记下来*/
int a=0;
printf("输入1-7之间的一个数:");
scanf("%d",&a);
if(a>0&&a<8)
printf("%s\n",*(day+a-1));
else printf("输入数字不在1-7之间\n");

}

void main()
{
//假设第一天是星期一(Monday)的话
char *day[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};
int select=0;
printf("输入1-7之间的一个数:");
scanf("%d",&select);
switch(select)
{
case 1:
case 2:
case 3:
case 4:
case 5:
case 6:
case 7:printf("%s\n",*(day+select-1));break;
default:pr
