I know that std::vector uses a contiguous block of memory, but I often see people use vectors of vectors, even when they modify the number of elements in these vectors contained within an outer ...
Been brushing up on my C++ lately, on Ubuntu QQ. I love the Qt framework for everything, especially building GUI's. I became quite familiar with it when using PyQt over the last few years. When ...
I've run 3 different experiments involving C++ lists and vectors. Those with vectors proved more efficient, even when a lot of insertions in the middle were involved. Hence the question: in which ...
In the C++ STL, priority_queue (heap) can be used with any underlying container, such as a deque. How does the implementation stay O(log n) if deques don't swap an item in index a with index b in ...
I know in some areas (game industry, for example), STL is not recommended. So my question is: is it really a good practice not to use STL in some cases? If so, what's the biggest reasons of not using ...
I recently started using <vector.h> library and I was wondering, since all the operations are already implemented, IF the method of the sorting algorithm is the most efficient one. Everything ...
I want to write a class which offers two sequences of elements to its users. The first one (lets call it "primary") is the main of the class and will be use 80% of the time. The second one (lets call ...
When I write high-level documentation about what an algorithm does, I use the term "array" to refer to the data structure on which the algorithm operates even though the actual data structure is an ...
