The d_addatbeg( ) function adds a node at the beginning of the existing list. This function too accepts parameter dura, which holds an integer to be added to the Jist.Memory is allocated for the new node whose address is stored in q. Then num is stored in the data part of the new node. A NULL value is stored in prev part of the new node as this is going to be the first node of the list. The next pari of this new node should contain the address of the first node of the list. This is done through the statementq -> next = p;Now what remains to be done is to store the address of this new node into the prev part of the first node and make this new node the first node in the list. This is done through the statements

History Of C..
In the beginning was Charles Babbage and his Analytical Engine, a machine
he built in 1822 that could be programmed to carry out different computations.
Move forward more than 100 years, where the U.S. government in
1942 used concepts from Babbage’s engine to create the ENIAC, the first
modern computer.
Meanwhile, over at the AT&T Bell Labs, in 1972 Dennis Ritchie was working
with two languages: B (for Bell) and BCPL (Basic Combined Programming
Language). Inspired by Pascal, Mr. Ritchie developed the C programming
language.
My 1st Program...
#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n");
printf ("\t\t\t*******Pankaj *******\n");
printf ("\t\t\t********************************\n");
printf ("\t\t\t\"Life is Good...\"\n");
printf ("\t\t\t********************************");
getch ();
}
Next Step...
#include
#include
void main ()
{
clrscr ();
printf ("\n\n\n\n\n\n\n\n");
printf ("\t\t\t --------------------------- \n\n");
printf ("\t\t\t | IGCT, Info Computers, INDIA | \n\n");
printf ("\t\t\t --------------------------- ");
getch ();
}
