can anybody please tell me why my program in visual C++ 2008 is not running due error #include<iostre am.h>?

You want:

#include <iostream>

instead.

I cant see my output window.

Either you are not compiling it as a console application or you should add something like
[code=cpp]
std::cout << "Press Enter or Return to continue.\n";
std::cin.get();
[/code]
or system("pause") ; in windows to pause the program before it exits.
