What is a copy constructor?Only a single parameter, which is a reference to objects of this class type (commonly used const adornments), is called a copy constructor.When do I use the copy constructor?1. Displays or implicitly initializes an object

The title of the article in this section is: Extract the parameter-independent code from templatesLearning this section of the article first need to understand one thing, that is, template instantiation process will not repeat?Let's give an example:#

Previously written merge sorting algorithm, but time too long, forget how to write, (also drunk). Just review the algorithm when encountered this problem, and then re-write a bit, the encounter some of the problems in the way to record.The core is

The linear time selection problem, in fact, is an extension of the random fast sorting algorithm, IE, can be achieved by small changes to the random fast sorting algorithm.The algorithm still refers to the relevant content in the introduction of the
