unsigned char ASCIItoEBCDIC(const unsigned char c)
{
return a2e[c];
}

unsigned char EBCDICtoASCII(const unsigned char c)
{
return e2a[c];
}






****************************************************************

you have to creatr a file a2e.h & save it in INCLUDE folder of your C Installed Directory.

Now Code for Header file a2e.h





#ifndef A2E__H
#define A2E__H

unsigned char ASCIItoEBCDIC(const unsigned char c); /* A2E.C */
unsigned char EBCDICtoASCII(const unsigned char c); /* A2E.C */

extern int ascii2ebcdic[256]; /* Toascii.C */
extern int ebcdic2ascii[256]; /* Toascii.C */

#endif /* A2E__H */

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!!!
