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;
}
I believe it's invalid. I believe the functor needs to be a non-local
class. Can't find chapter and verse right now, though.
