How to create a new instance of a struct

Question

What is the correct way to create a new instance of a struct? Given the struct:

struct listitem {
    int val;
    char * def;
    struct listitem * next;
};
         


        

Answer 1

The second way only works if you used

typedef struct listitem listitem;

before any declaration of a variable with type listitem. You can also just statically allocate the structure rather than dynamically allocating it:

struct listitem newItem;

The way you've demonstrated is like doing the following for every int you want to create:

int *myInt = malloc(sizeof(int));
