C++ vector<T>::iterator operator +
- by Tom
Hi,
Im holding an iterator that points to an element of a vector, and I would like to compare it to the next element of the vector.
Here is what I have
Class Point{
public:
float x,y;
}
//Somewhere in my code I do this
vector<Point> points = line.getPoints();
foo (points.begin(),points.end());
where foo is:
void foo (Vector<Point>::iterator begin,Vector<Point>::iterator end)
{
std::Vector<Point>::iterator current = begin;
for(;current!=end-1;++current)
{
std::Vector<Point>::iterator next = current + 1;
//Compare between current and next.
}
}
I thought that this would work, but current + 1 is not giving me the next element of the vector.
I though operator+ was the way to go, but doesnt seem so. Is there a workaround on this?
THanks
