Should this work?

I got this code from MSDN for a FAQ for Visual C++ 4.2

I saw this code, ran my eyes over it and I am wondering if the code is legal, according to the standard.

Code:

//piglatin.cpp
#include <string>
#include <iostream>
//convert a string to piglatin
string piglatin(const string& s)
{
    string s1 ;
    string s2(" .,;:?") ;  //word separators
    //word boundary markers
    size_t start, end, next, p0 ;
    int done = 0 ;
    start = end = next = 0 ;
    while (!done)
    {
        // Find start of word.
        start = s.find_first_not_of(s2, next) ;
        // Find end of word.
        // Check for end of string.
        p0 = s.find_first_of(s2, start) ;
        end = (p0 >= s.length()) ? s.length() : p0 - 1 ;
        // Copy all the word separators.
        s1 = s1 + s.substr(next, start - next) ;
        // Convert word to piglatin.
        s1 = s1 + s.substr(start + 1, end - start) + s[start] + "ay" ;
        
        next = end + 1;
        // Check for end of string.
        if( next >= s.length())
            done = 1 ;
            
    }
    return s1 ;
}
void main()
{
    string s("she sells sea shells by the sea shore") ;
    cout << "s = " << s << endl ;
    cout << "\npiglatin(s) = " << piglatin(s) << "\n"<< endl;   
}

you know, even in the recent VC++ tutorial, they still used void main()...
no wonder windows has so many problems.
note: haven't tried compiling yet but I know it will compile...

Shouldn't it say

Code:

using namespace std;

under the includes...
also, i really think void should be changed to int (on main) and a return 0; added to the bottom. OR AT LEAST
__asm mov eax, 0x0
right?

I take that back, their own tutorial won't even compile:

Code:

--------------------Configuration: haha - Win32 Debug--------------------
Compiling...
haha.cpp
d:\program files\microsoft visual studio\myprojects\haha\haha.cpp(5) : error C2146: syntax error : missing ';' before identifier 'piglatin'
d:\program files\microsoft visual studio\myprojects\haha\haha.cpp(5) : error C2501: 'string' : missing storage-class or type specifiers
d:\program files\microsoft visual studio\myprojects\haha\haha.cpp(5) : fatal error C1004: unexpected end of file found
Error executing cl.exe.

haha.exe - 3 error(s), 0 warning(s)

LOL

With the addition of using namespace std, changing main to int, and adding a return value of 0 it compiles fine for me on gcc.

yeah thats what I thought...

but I can't believe this actually worked on the older compiler for Microsoft. The newer tutorial hasn't changed much either though...
