STL Standard Template Library, which provides some data structure containers similar to Java collection classes. such as eque, list, vector, map and so on. It also provides some algorithms that support these containers and iterators that traverse

Map is ordered by key, key cannot be duplicated.1. Map.lower_bound (): Press key to find, if the found key exists, return to that location, if there is no value returned greater than the minimum key location1#include 2#include 3 using namespacestd;4

Get different objects through factory factory in simple Factory mode, but with one obvious drawback-simple Factory mode systems are hard to scale!Once you add a new product, you have to modify the simple factory method, which makes the

We create different objects with Factory.For example, if you create an interface for a car, create an object that implements the interface through the Factory factory, and create different objects based on our choices.Create a car interface ///

In C # inheritance, try to use the relevant modifiers: override and new. Both modifiers can be overridden in a new subclass, overriding the parent class method with the same name.Override: An abstract or virtual implementation that extends or
