Re: Is this a legal C++ code?

Hi everyone,

I originally implemented following code in Visual StudioC++ 2005 with
SP1, it gets compiled and runs well. However when I try to compile it
in VC++ 2005 without SP, the compiler compains about an internal error
and stop the building process.

I also tried to compile it in gcc, but I get a error message of:
"error: no matching function for call to
`for_each(__gnu_cxx::__normal_iterator<std::string*,
std::vector<std::string, std::allocator<std::string> > >,
__gnu_cxx::__normal_iterator<std::string*, std::vector<std::string,
std::allocator<std::string> > >, foo(std::vector<std::string,
std::allocator<std::string> >&)::Doer)'

can anyone tell me if the following code is a valid C++ code per
current standard?

#include <cstdlib>
#include <iostream>
#include <vector>
#include <iterator>
#include <algorithm>

using namespace std;

void foo(vector<string>& strings)
{
     struct Doer
     {
            Doer() : nCount('0'){}

            void operator()(string& str)
            {
                 str += nCount;
                 nCount++;
            }

     private:
             char nCount;
     };

     for_each(strings.begin(), strings.end(), Doer());
}

int main(int argc, char *argv[])
{
    vector<string> strings(5, "Test");
    foo(strings);

    copy(strings.begin(), strings.end(),
ostream_iterator<string>(cout, "\n"));

    return EXIT_SUCCESS;
}
