Well thank u all for ur answers.I found one simple answer by a comment from Mr. Hao below the question. his answer is simple program like this

Turbo C(DOS program):

char far* src = (char far*) 0xB8000000L; 
*src = 'M'; 
src += 2; 
*src = 'D'; 

or try this: http://en.wikipedia.org/wiki/Brainfuck :) – //Hao (an hour ago)

I tried it on Turbo C and its working. I wanted a simple solution like this and I wanted to accept it as correct answer but he(Hao) gave it as a comment so I pasted it here for other users to know about this on behalf of him and accepted it. Once again thank u Mr.Hao.
