[The ICE Man]

your header files are incorrect;

#include <iostream.h>

You should be using this header file when it comes to c++...:P

#include <iostream>

Also you are missing

using namespace std;

Also using getch() is very bad practice you should instead use a different method...

[mrnutty]

change this :

# include <iostream.h>
# include <conio.h>
main ()

to this :

#include <iostream>
#include <string>
using namespace std;
int main ()

and instead of getch() use this :

cin.clear();
cin.ignore(256,'\n');
string pause;
getline(cin,pause);
