ANSWER: > please tell whether i can run C++ programs in visual studio or not....

Yes, you can compile and build and run C++ programs using Microsoft Visual Studio 2010.

iostream.h is not a C++ header file.

For a list of standard C++ headers, see http://cplusplus.com/reference/

Try this program:

#include <iostream>
using namespace std ;

int main()
{
       cout << "hello world!\n" ;
}

or, alternately:

#include <iostream>

int main()
{
       std::cout << "hello world!\n" ;
}

These are not errors, merely informational messages which you can safely ignore for now.

The program has executed and exited without errors ( code 0 ).



If you want the program to wait after "hello world!\n" is printed, add this just below it; it will wait till you press the enter key:

   std::cout << "press the enter key to quit: " ;
   std::cin.get() ;
