Why doesn't this work?
See the compiler output below.

What clue tells you it doesn't work? An error message? Could you

No.

Thanks.

Reposting a complete desierable compilable part:
pt2.h
#include <string>
#include <vector>
using namespace std;
// Auxiliary functions
class Aux
{ private:
public:
static string &toLower(string &s);
static void toLower(vector<string&vs); // Changing the name works!
};
pt2.cpp
#include "pt2.h"
string &Aux::toLower(string &s)
{ transform(s.begin(),s.end(),s.begin(),::tolower);
return s;
}
void Aux::toLower(vector<string&vs) // Changing the name works!
{ transform(vs.begin(),vs.end(),vs.begin(),Aux::toLo wer);
}
int main()
{
return 0;
}
This code doesn't compile (because 'string' or 'vector' are undefined).
:-)
No!. This is part of a bigger program. The needed headers are there.
I think the compiler cannot determine which "toLower" to use in the 2nd.
transform.
Is there a way I can force it to use the first?
