Vector pop.back

[tomazi]

Hello People....

I got a vector that stores distances between two points, Now i iterate over this vector to retrieve the values stored in it that I will use for different calculations. But before I do that i want to makes sure that the vector does not store any values that are == 0 for memory management.

I have this code:

	double Pt3; 
	double Pt4; 
	for(vector<Point>::iterator iter_b = Right_Arm_xy.begin()+1; iter_b != Right_Arm_xy.end(); ++iter_b)
	{
		
		Pt3 = pow((double) iter_b->x - (iter_b -1)->x,2);
		Pt4 = pow((double) iter_b->y - (iter_b -1)->y,2);

			double result_b;
			result_b  = (Pt3 + Pt4);
		
			Right_Point_distance.push_back(sqrt(result_b));

	}


	
	for(vector<double>::iterator iter_dist = Right_Point_distance.begin(); iter_dist != Right_Point_distance.end(); ++iter_dist)
	{
		
		if(*iter_dist == 0)
		{
			Right_Point_distance.pop_back();
		}	
	
	}

I think the way I am trying to pop.back an element is not correct....could anybody suggest a solution to what i am trying to achieve. Regards

	for(vector<double>::iterator iter_dist = Right_Point_distance.begin(); iter_dist != Right_Point_distance.end(); /*nothing*/)
	{
		if(*iter_dist == 0)
		{
			iter_dist = Right_Point_distance.erase(iter_dist);
		}
		else ++iter_dist;
	}

Also I like that you use tabs and not spaces for indentation :) it's too bad the forum stretches out tabs like a maniac.
