As far as I understand it fundamental types are Scalar and Arrays are aggregate but what about user defined types? By what criteria would I divide them into the two categories? struct S { int i; int j }; class C { public: S s1_; S s2_ }; std::vector<int> V; std::vector<int> *pV = &v; Short version: Types in C++ are: Object types: scalars, arrays, classes, unions Reference types Function types (Member types) [see below] void Long version Object types Scalars arithmetic (integral, float) pointers: T * for any type T enum pointer-to-member nullptr_t Arrays: T[] or T[N] for any complete, non

I'm interested in writing some basic computerized object recognition application, so I figure I need some theoretical background in image processing algorithms, along with some AI for decision making capabilities. I'm a computer science graduate, and one day I plan to get my Master's degree, hopefully in one of these fields. In the mean time, I'd like to get a head start and do some self-learning. So my question is, where do I start? I'd appreciate an arrow in the right direction, a few links if possible. Ivan You may want to check out the answers to these similar question: Image processing

With a RESTful service you can create, read, update, and delete resources. This all works well when you're dealing with something like a database assets - but how does this translate to streaming data? (Or does it?) For instance, in the case of video, it seems silly to treat each frame as resource that I should query one at a time. Rather I would set up a socket connection and stream a series of frames. But does this break the RESTful paradigm? What if I want to be able to rewind or fast forward the stream? Is this possible within the RESTful paradigm? So: How do streaming resources fit within

I've been looking through a few notes based on this topic, and although I have an understanding of threads in general, I'm not really to sure about the differences between user-level and kernel-level threads . I know that processes are basically made up of multiple threads or a single thread, but are these thread of the two prior mentioned types? From what I understand, kernel-supported threads have access to the kernel for system calls and other uses not available to user-level threads. So, are user-level threads simply threads created by the programmer when then utilise kernel-supported

(Just a theoretical question - for non-gui apps) Assuming I have this code with many awaits : public async Task<T> ConsumeAsync() { await A(); await b(); await c(); await d(); //.. } Where each task can take a very short period of time , Question (again , theoretical) There could be a situation where the overall time dealing with all those "releasing back threads" and "fetching threads back" ( red & green here :) Is taking more time than a single thread which could done all the work with a small amount of delay , I mean , I wanted to be the most productive , but instead , since all those

How do I check if a directed graph is acyclic? And how is the algorithm called? I would appreciate a reference. FryGuy I would try to sort the graph topologically , and if you can't, then it has cycles. Doing a simple depth-first-search is not good enough to find a cycle. It is possible to visit a node multiple times in a DFS without a cycle existing. Depending on where you start, you also might not visit the entire graph. You can check for cycles in a connected component of a graph as follows. Find a node which has only outgoing edges. If there is no such node, then there is a cycle. Start a
