Answer 5

You are using old Turbo C++ ide, so try this...
1.
in header file, change
from
#include<iostream>
to
#include<iostream.h>
2.
there may be chances that you can remove the second line
using namespace std;
But try with and without, so you know if its making any effect or not.
Rest of the code is ok.
Kindly comment back to tell if it works or if it doesn't.
If it does, download CODE::BLOCKS ide. No one use Turbo C++ now, instead of indian education system (sad).
