Memory Representation
  • 2-D arrays are Stored in contiguous memory location row wise.
  • 3 X 3 Array is shown below in the first Diagram.
  • Consider 3×3 Array is stored in Contiguous memory location which starts from 4000 .
  • Array element a[0][0] will be stored at address 4000 again a[0][1] will be stored to next memory location i.e Elements stored row-wise
  • After Elements of First Row are stored in appropriate memory location , elements of next row get their corresponding mem. locations.

Basic Memory Address Calculation :

a[0][1] = a[0][0] + Size of Data Type
ElementMemory Location
a[0][0]4000
a[0][1]4002
a[0][2]4004
a[1][0]4006
a[1][1]4008
a[1][2]4010
a[2][0]4012
a[2][1]4014
a[2][2]4016

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 ();

}

Hits!!!
