handcrafted lists for int, chat* etc could also be written ...
here is soem for pack of str_list (fir str list), as you usually need more than one
i used resizable list of resizable lists and so on back teh *wrote on thsi here but this form with _New as above i noticed first time here
// sickle.h
   struct str_list_entry { char* str;};
   const int str_lists_max = 10;
    str_list_entry* str_list[str_lists_max] = {NULL};
     int str_list_size[str_lists_max] = {0};
   str_list_entry* str_list_new(int N)  {
       str_list[N] = (str_list_entry*) realloc(str_list[N], ++str_list_size[N] * sizeof(str_list_entry) );
       return &str_list[N][str_list_size[N]-1];  }
//main.c
#include "sickle.h"
   void Test()
   {
     *str_list_new(0)={"ala"};
     *str_list_new(0)={"ma"};
     *str_list_new(0)={"kota"};
     *str_list_new(1)={"starcrawler"};
     *str_list_new(1)={"skating polly"};
     *str_list_new(1)={"lil xan"};
     *str_list_new(1)={"kenny mason"};
      for(int i=0; i<str_list_size[0]; i++)      printf("\n %s ", str_list[0][i].str);
      for(int i=0; i<str_list_size[1]; i++)      printf("\n %s ", str_list[1][i].str);
   }
