Re: Operater < overloading for struct problem

I am having trouble overloading the < operator for an assignment. I
use a struct that contains information and I would like to sort this
structure using STL sort with my own criteria of sorting. Basically, I
would like to sort on visitor count of the Attraction structure.
However, it never uses the < overloaded operator with my code.

Handler.h:

#ifndef H_HANDLER //Guard
#define H_HANDLER

#include <iostream>
#include <vector>
using namespace std;

struct Attraction {
string name;
int visitors;
};

class Handler { //Define the class Handler

private:
vector<Attraction*> attractions ;
vector<Attraction*>::iterator p ;

public: //Public functions
~Handler();
void addAttraction(string name, int visitors);
void printAttractions();
};

#endif

and in the Handler.cpp I have:

Handler.cpp - snippet:

bool operator<(const Attraction& a,const Attraction& b){
return a.visitors < b.visitors;
}

Here is the function that performs the sort after adding a value:

void Handler::addAttraction(string name, int visitors){

Attraction *attr;
attr=new Attraction();

attr->name=name;
attr->visitors=visitors;

attractions.push_back(attr);
sort(attractions.begin(),attractions.end());

}

However, whatever I do, it will never use the overloaded < operator
for sorting. What am I doing wrong?
