A binary heap is a heap data structure that takes the form of a binary tree. Binary heaps are a common way of implementing priority queues.[1]:162–163 The binary heap was
Sort, Binary Search, Merge Algorithms
Sort And Partial Sort You can sort a range with std::sort or std::stable_sort or sort until a position with std::partial_sort. In addition std::partial_sort_copy copies the partially sorted range. With std::nth_element you
Modifying Algorithms
Copy Elements and Ranges You can copy ranges forward with std::copy, backward with std::copy_backward and conditionally with std::copy_if. If you want to copy n elements, you

Smart Pointers
std::unique_ptr After we left the scope, both objects are destructed immediately and their memory is released to the heap. Let’s have a
Placement new operator in C++
Placement new is a variation new operator in C++. Normal new operator does two things : (1) Allocates memory (2) Constructs an object in

Resonance Circuits
Resonance in AC circuits implies a special frequency determined by the values of the resistance , capacitance , and inductance . For series resonance the condition of resonance is straightforward
Inductive Proximity Sensor
A inductive proximity sensor can detect metal targets approaching the sensor, without physical contact with the target. Inductive Proximity Sensors are roughly classified into

Understand std::move Because std::move does nothing but cast its argument to an rvalue, there have beensuggestions that a better name for it
