我可以指向数组的特定地址吗？

Question

我有几个问题:

1) 什么是

ps_lst_tmp->ps_greather = & ps_lst_tmp [1];

意思是？

2)如果我正确理解指针，那么如果我写在代码末尾

ps_lst_tmp++;

那么指针 ps_lst_tmp 将指向下一个元素，并且... ps_lst_nodes 是否也指向下一个元素？

整个代码:

struct s_node_lnk_lst  /* structure used for list  */
{
    sMSC_NODE             *ps_node;       /* node */
    unsigned long int      uli_occurs;    /* occurences */ 
    struct s_node_lnk_lst *ps_greather;   /* greather neighbour in list */
} *ps_lst_nodes = NULL,*ps_lst_tmp;

ps_lst_nodes = (struct s_node_lnk_lst *) malloc 
               (sizeof (struct s_node_lnk_lst) * uli_nb_items);
ps_lst_tmp     = ps_lst_nodes;
ps_lst_tmp->ps_greather = & ps_lst_tmp [1];

谢谢

Answer 1

ps_lst_tmp->ps_greather = & ps_lst_tmp [1] 与 ps_lst_tmp->ps_greather = ps_lst_tmp + 1

相同

ptr + i 相当于 &ptr[i]，ps_lst_tmp++ 相当于 ps_lst_tmp = &ps_lst_tmp[1].

因此，ps_lst_tmp++ 将指向 ps_lst_nodes[1]。同时ps_lst_nodes不会改变
