3.why code block not supportin <dos.h>...       

simple answer:
Mingw does not support building dos applications.

[reckless]

better of with open watcom if you need to develop for dos, an alternative is djgpp if you prefer using bash.

thnx a lot........
but wat about d first two ques,,,,,,,,is dis also because of failure in supporting <dos.h>

investigate. void main() is simply not standard C++, therefore it is not supported. standard C++ is int main().
