you have not write right syntax ptr = (struct node*)malloc(sizeof(struct node)); It is use to create a memory block in Ram. Mainly use in Data structure. Always use pointer variable to create a memory block because a pointer can contain adress of memory block. It create struct node size memory block. for more comment
