在尝试使用C语言中的字符串数组步进的方法时,我开发了以下小程序:

#include <stdio.h>
#include <stdlib.h>
#include <string.h>


typedef char* string;

int main() {
  char *family1[4] = {"father", "mother", "son", NULL};
  string family2[4] = {"father", "mother", "son", NULL};

  /* Loop #1: Using a simple pointer to step through "family1". */
  for (char **p = family1; *p != NULL; p++) {
    printf("%s\n", *p);
  }
  putchar('\n');

  /* Loop #2: Using the typedef for clarity and stepping through
   * family2. */
  for (string *s = family2; *s != NULL; s++) {
    printf("%s\n", *s);
  } …
