functor returning 0
- by Jon
I've recently started teaching myself the standard template library. I was curious as to why the GetTotal() method in this class is returning 0?
...
class Count
{
public:
Count() : total(0){}
void operator() (int val){ total += val;}
int GetTotal() { return total;}
private:
int total;
};
void main()
{
set<int> s;
Count c;
for(int i = 0; i < 10; i++) s.inset(i);
for_each(s.begin(), s.end(), c);
cout << c.GetTotal() << endl;
}
