Below code is for inserting data to the front of the node ,just wanted to know we have reassigned start = tmp ,i.e. start will point to the inserted node which is now new first node but how
Code:
int add_begin(int data)
{
struct node *tmp;
tmp=malloc(sizeof(struct node));
tmp->info=data;// put data
tmp->link=start;// point to nxt node
start=tmp; // start will point to inserted node
