C语言指针与数组

已知一个数组，利用数组下标和指针实现打印字符串，完成表格4。#include <stdio.h>int main(){ char weekday[][100]={"Sunday","Monday","Tuesday", "Wednesday","Thursday","Friday","Saturday"};char *p1 = weekday;char (*p2)[7]= weekday;char *p3[7] ={weekday[0],weekday[1],weekday[2],weekday[3], weekday[4], weekday[5],weekday[6]};printf("%s\n",【1】);printf("%s\n",【2】);printf("%s\n",【3】);printf("%s\n",【4】);}

Answer 1

#include <stdio.h>
int main()
{
char weekday[][100]={"Sunday","Monday","Tuesday", "Wednesday","Thursday","Friday","Saturday"};
char *p1 = weekday;
char (*p2)[100]= weekday;//这里必须是100
char *p3[7] ={weekday[0],weekday[1],
weekday[2],weekday[3], weekday[4], weekday[5],
weekday[6]};
printf("%s\n",【1】);
printf("%s\n",【2】);
printf("%s\n",【3】);
printf("%s\n",【4】);
}

然后表格依次填

p1       p2[0]    p3[0]              
p1+100   p2[1]    p3[1]
p1+200   p2[2]    p3[2]
