// File:  Ex1-1.cpp
// This example illustrates some of the basic differences of C and C++:
// Comments
// cin and cout for input and output
// declarations of variables almost anywhere
// use of type bool

#include <iostream>		// instead of <stdio.h> or <iostream.h>
using namespace std;

/* You can still use the old comment, */

/* but you must be // very careful
about mixing them */

// Your best bet is to use this style for 1 line or partial line comments
/* And use this style when your comment
consists of multiple lines */
