Please in the future use code tags.

I don't see where that error could be coming from.... but I do see two errors:
1. iostream and iomanip should not have the .h extension
2. you either need to preceed cout with the scope std (as in std::cout) or you need to add the statement using namespace std; before your main method.

Non errors that are bad coding practice:
1. main should not be void, it should return int
2. instead of using getch() to pause your program, you should use something else like cin or getline, there is a whole topic about this here http://cplusplus.com/forum/beginner/1988/

Hope this fixes your issue.
