Thread: Question about dynamic memory allocation

Hi guys , i have a question about din. memory alloc. and i want to ask it with an example.

Code:

/* here is my struct */
struct node
{
      int data;
      struct node *next;
}
/* here is my simple making node function*/

struct node *makenode(int value)
{
        struct node *np;
        np=malloc(sizeof(struct node));
        np->data=value;
        np->next=NULL;
}

What if i did not write the np=malloc(sizeof(struct node)); line, Does the code work properly ? When i need to take a place from memory using with pointer and when i dont need ? Thank you for your answers.
