Question

    #include<stdio.h>

    typedef struct
    {
        int *u;
        struct node next;
    } *node;

    int main()
    {
        return 0;
    }

What is meant by *node here? I don’t get it. I think there should be a node here but it is compiling anyway.

Answer 1

Here typedef defines a new type, node, which is a pointer to the structure.

The code in the question may not compile since struct node doesn’t appear to be defined anywhere and yet it’s used inside of the structure.
