in other programming language like

[hughLg]

in other programming language like Pascal, we can refer the link list like:

top^.next^.data = 123;
top^.next^.next = nil;

but in C, i don't know what's the problem. i just know when i try to compile the following code, error message occurs:

top->next->data = 123;
top->next->next = NULL;

the structure type is defined is like this:

typedef struct {
int data;
struct List *next;
} List;

i have no any problem when i write these:

top->data = 123;
top->next = NULL;

thank you for you attention.

actually, i'm not a actual C/C++ programmer. i call myself as programmer here because i want to be a real programmer. and the programming language i mot like is C/C++. is these 2 languages can produce whatever things? no matter we want or not?

Try this:

typedef struct list_tag {
int data;
struct list_tag *next;
} List;

The code that's giving you an error looks like it should work as long as

first->next

is something other than 0. Is the error you get a compiler error, or does the program crash in the middle of execution?

What you're doing in that code is accessing the second item from the top. It's not going to work if there's not a first item from the top yet.
