Hi,
change:
Quote
#include <iostream.h>
to
Quote
#include <iostream>
and add below includes:
Quote
using namespace std;
(or change all cout's and cin's to std::cout/cin). This should help.
best regards,

Hello,

Here you can find some suggestion on good C++ books.

Best wishes,
Michael

conio.h is a non-standard header file.

You already commented clrscr() and getch() doesn't work either 'cause it's part of conio.

C++ states you should include the C header math.h this way: #include <cmath>

Everything else seems to be fine.

tiwag: I don't get it, what's your point? I was just naming problems with that source code, and using conio.h is one of those.

He maybe comes from Turbo C++ (at least that happened to me), so it's time to wake up and realize many things have changed since the 80's. It's somehow part of the learning process :)

Well, I got tiwag's answer in PM and it's right that MinGW comes with a conio.h, but it's a reduced version of it.

If you have plans to use conio.h in the meanwhile I suggest you trying the one Dev-C++'s ppl was working in a long time ago which can be found here.

It provides some extra functions, like clrscr().

The idea would be to "merge" the .c and .h files so it wouldn't require anything else than a conio.h.
