C数组字符串数组

Question

在C中,我需要静态地预分配一个数字数组,每个数字与不同的字符串数组相关联.像下面这样的代码可以做到这一点:

struct number_and_strings {
  int  nnn;
  char **sss;
}

static struct number_and_strings my_list[] = {
  {12, {"apple","banana","peach","apricot","orange",NULL}},
  {34, {"tomato","cucumber",NULL}},
  {5,  {"bread","butter","cheese",NULL}},
  {79, {"water",NULL}}
}

Answer 1

sss是指向指针的指针.因此无法将指针数组直接分配给它.您可以使用复合文字(这是C99功能)分配如下:

static struct number_and_strings my_list[] = {
      {12, (char*[]){"apple","banana","peach","apricot","orange",NULL}},
      {34, (char*[]){"tomato","cucumber",NULL}},
      {5,  (char*[]){"bread","butter","cheese",NULL}},
      {79, (char*[]){"water",NULL}}
    };
