我可以通过这种方式创建链接列表吗？

Question

struct node
{
    int data;
    node *link;
} n1, n2;
n1.data = 1;
n1.link = &n2;  //in the link pointer of n1 store the address of n2
n2.data = 2;

Is the above code correct? What command should I write to print the data of the node whose address is stored in the link of n1.

Answer 1

Is the above code correct?

It will compile, and run, but it would make sense to set n2.link = NULL; so that your other code can find where the end of the list is.

What command should I write to print the data of the node whose address is stored in the link of n1.

printf("%d\n", n1.link->data);
