复杂数据类型的向量的迭代器

Question

I have a structure like below

struct voxelParam
{
int voxelID;
int paramID;
}

and I have a vector of the structure

std::vector<voxelParam*> &finalist;

I want to navigate through the vector using iterators

for (std::vector<voxelParam*>::iterator it = finalList.end(); it != finalList.begin(); --it)
{
    //I want to get 'it->voxelID' but that is not the way to do it.   
}

How do I access the voxelID part using the iterator defined

Answer 1

Use (*it)->voxelID instead.

Note that finalist is a reference of a vector of voxelParam pointers . So *it gives the value at the iterator which is voxelParam* , which is then used to access the members via -> .
