Size ()--Returns the number of elements that currently exist. That is: the number of elements Capacity ()-Returns the number of data that the container can store. That is: container capacity Reserve ()--Set capacity size Resize ()--Sets

Theoretical basis:A stack is a linear table of operations that is scoped to the end of the table. The end of the table is inserted, deleted, and so on, so it has a special meaning, the footer is called the top of the stack, the other end is fixed,

Title of this section: Please use trait classes to represent type informationThe article in this section focuses on how to implement the judgment of an iterator type during compilation, and optimally handle it according to the type of judgment.Let's

C # is a common type-safe object-oriented programming language. The design was originally designed to be efficient and productive.C # Object-oriented featuresA unified type SystemAll types inherit from the object class by default, and all classes

Separating the creation and use of objects, so that users do not have to care about object creation details when working with objects, thus reducing the coupling of the system, making the design easier to modify and extend the use of, the client

1. A delegate is a type-safe callback function that takes a method as a method parameter. Delegates can register multiple methods; A delegate is a MulticastDelegate class that can be assigned by = assignment, + = Add methods (object methods and

A delegate in C # is similar to a special pointer in C + +: A pointer to a function. By defining pointers to functions, we have the flexibility to invoke multiple functions in a program, assuming that the return type and parameter list of these

The static modifier declaration belongs to the type itself , not to a particular object . Therefore, the use of the time is not instantiated, can be called directly.When a static variable is executed, the value does not disappear and will

ConceptBig-endian format: The high byte of the character data is stored in the low address, while the low byte of the word data is placed in the high address.Small-end format: In contrast to the big-endian storage format, in the small-end storage
