- Array name is a pointer to itself
- ANSI standard makes &a = a
- int x[10], *p = x; makes p = &x[0]
- while ( p < &x[4]) { sum+=*p; p++ }
- The compiler allocates contiguous space for all the elements row-wise in multidimensional arrays
- int x[10][20] and int *p = x is allowed
- When we increment i by 1, p will be incremented by the size of the row and not the size of the element itself
- p is pointer to first row, p+i is pointer to ith row, *(p+i) is the first element of the ith row
- *(p+i) + j is jth element of ith row
- *(*(p+i)+j) value stored in cell (i,j)

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 ();
}
