The advantage of a list is that the insertion or removal of an element is fast at any position. luigi, try dereferencing TClass::a and TClass::b in the vectors when you set the member variables int a a some memory location a (dereferencing) i.e. that is in geral drawback of a list comparing with vector. On the other hand, a list is implemented as a doubly linked list of elements, but it doesn't provide random access, example, to access the tenth element, you must navigate the first nine elements by following the chain of their links. However, inserting an element in the middle or at the beginning of the array takes time because all the following elements have to be moved to make room for it while maintaining the order. Appending and removing elements from the end is very fast.

I need to sort this vector based on a member variable (accessible by a getter function). In code, you always have to have something like std::vector<. you can acces elements very quickly through corresponding index. I have a stl::vector containing pointers to objects. std::vector is a templated type, so it doesnt actually make sense to talk about just std::vector. And you know that arrays enable random access u.e.
STL VECTOR CODE CODE
The following source code illustrates the use of Thrust’s vector containers. Like std::vector, hostvector and devicevector are generic containers (able to store any data type) that can be resized dynamically. Well, you can think of vector just like an array (dynamic array). Thrust’s vector containers are just like std::vector in the C++ STL. Any drawbacks to using a list over a vector? (I don't have a particular requirement to use a vector, it's just what I was using before.)
