C语言 编写一个程序 输入周几号 输出改天的英文名 要求用指针处理

Question

输入的周几号必须合法 如果不合法 循环重输 知道合法

Answer 1

1 定义字符串指针数组，指向7个英文单词，分别为周一到周日。

2 输入周几号。

3 取出对应的英文单词并输出。

代码：

int main(void) 
{
    int n;
    char *week[]={"Monday","Tuesday","Wednesday","Thursday","Friday","Saturday","Sunday"};
    scanf("%d",&n);
    puts(week[n-1]);
    return 0;
}

Answer 2

#include <stdio.h>
void getint();
void putint(int *p);
void getint()
{
int a,*p;
p=&a;
printf("请输入1—7的星期数字\n");
scanf("%d",&a);
putint(p);
}

void putint(int *r)
{
if(*r!=1&&*r!=2&&*r!=3&&*r!=4&&*r!=5&&*r!=6&&*r!=7)
{
printf("输入错误，请重新输入\n");
getint();
}
else
switch(*r)
{
case 1:printf("monday\n");break;
case 2:printf("tuesday\n");break;
