    "end of file" in Windows

    Hi, I've been reading B. Stroustrup's FAQ and found
    How do I write this very simple program?

    What is interesting is this sentece:
    The program ends reading input when it sees "end of file". If you run the program from the keybord on a Unix machine "end of file" is Ctrl-D. If you are on a Windows machine that because of a bug doesn't recognize an end-of-file character, you might prefer this slightly more complicated version of the program that terminates input with the word "end":
    I test it on my Dev-Cpp compiler with this code
    Code:
            #include<iostream>
    	#include<vector>
    	#include<algorithm>
    	using namespace std;
    
    	int main()
    	{
    		vector<double> v;
    
    		double d;
    		while(cin>>d) v.push_back(d);	// read elements
    		if (!cin.eof()) {		// check if input failed
    			cerr << "format error\n";
    			return 1;	// error return
    		}
    		if(cin.eof())
    		{
                         cout<<endl<<"Test is OK"<<endl;
                    }
    
    		cout << "read " << v.size() << " elements\n";
    
    		reverse(v.begin(),v.end());
    		cout << "elements in reverse order:\n";
    		for (int i = 0; i<v.size(); ++i) cout << v[i] << '\n';
    
    		return 0; // success return
    	}
    And after entering Ctrl-Z I saw line "Test is OK".
    Can you comment this?
    I'd like to read your opinion on this.

    Cheers!

    There have been a large number of different compilers for windows machines, some of which are less buggy than others.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Ok, so under Windows Ctrl-Z means end of file and I can assume this when working with MSVC++ .net and Dev-Cpp?
