how to output any charactor on to screen without using "printf"
fuction.(through video buffer-how to?)

[anan...@sifycorp.com]

if hope ur using turboc , under dos or windows, this works only on those

you can do an output to screen by directly accessing the video ram




char far * video_ram = (char far *)0xB8000000; //if your card is CGA use
0xB0000000;
char * data="Ananth.G";
int i=0;

while (data) {
*(video_ram+i)= *data;
*(video_ram+i+1)= 50; // 50 is the color, try something else if u
dont get any char on screen
i+=2;
++data;
}

hope this works, i dont have turboc for checking...

yours,
ananth.g

hey babu,
with the help of Video Ram we can easily achieve this.

For this you have to use far pointer.

char far *video=(char far*) 0xb0008000L;

and in VRAM each charecter take 2 bytes one for charecter to be display and another for colour of that charecter.

You just use these address for printing .
