本文通过两个示例展示了如何使用C语言中的数组和指针来打印一周的每一天及其对应的数字。第一个示例使用了一维字符数组，第二个示例则通过二维数组实现了相同的功能。

#include <stdio.h>
#include <locale.h>

char *Weekdays[] = {
   "Monday",
   "Tuesday",
   "Wednesday",
   "Thursday",
   "Friday",
   "Saturday",
   "Sunday"
};

void printWeekday()
{
   char **ptr=Weekdays;
   int i=0;

   printf("%p\n",i,&Weekdays[0]);
   printf("%p\n",i,&ptr);

   for(i=0;i<7;i++){
       printf("i=%d:%s\n",i,*ptr);
       ptr++;
   }
   printf("\n");
}

char *Weekdays2[][2] = {
   {"Monday",       "1"},
   {"Tuesday",       "2"},
   {"Wednesday",   "3"},
   {"Thursday",   "4"},
   {"Friday",       "5"},
   {"Saturday",   "6"},
   {"Sunday",       "7"}
};

void printWeekday2()
{
   char **ptr=&Weekdays2[0][0];
   int i=0;

   printf("%p\n",i,&Weekdays[0]);
   printf("%p\n",i,&ptr);

   for(i=0;i<7;i++){
       printf("i=%d:%s \t",i,*ptr);
       ptr++;
       printf("%s\n",*ptr);
       ptr++;
   }
   printf("\n");
}

输出结果为：

linxuan__ ../usrAppInit.c 43
0x0
0x0
i=0:Monday      1
i=1:Tuesday     2
i=2:Wednesday   3
i=3:Thursday    4
i=4:Friday      5
i=5:Saturday    6
i=6:Sunday      7
