Hi
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
