To use old C header files, use
#include <c[headerfilename]>
For example,
#include <cstdlib>
instead of
#include <stdlib.h>
To use iostream, you write:
#include <iostream>
However, to use cout and endl, you have to either put the line:
using namespace std;
OR
using std::cout;
using std::endl;
However, if I remember correctly, conio.h is not an Ansi standard
include file, it's a Borland-specific file. If you're going to use
that, you're going to have to track down someone's implementation of
that for mingw.
