14.3 Write a program to use far pointer.

#include<iostream.h>

#include<constream.h>

int main()

{

clrscr();

char far *s; // pointer declaration

s=(char far*)0xB8000000L; // starting address

*s=‘W’; // displays character on the screen

return 0;

}

OUTPUT

W

Explanation: Character pointer *s, which is a far pointer, is declared. The address

0xB8000000L is assigned to it. It is ...
