need to provide the code for the destructor, but instead the default destructor performs the operation automatically. However, if you need to do some important things before you delete an object instance, you should provide a specific destructor.For example, if a variable is out of range, the code cannot access it, but the variable still exists somewhere in the computer's memory. Only in. NET runtime to perform its garbage collection, the instance is
object-oriented design phase First, let's talk about the methods used to create objects when the current programming language implements objects. C # Is a type-Based Static language. The type specifies the state features and behavior features that an object can possess. All
a good software design is to try to change If your software is hard to change, the problem may occur when you want to improve the design. Now let's see if several instruments can be easily changed. If a new instrument is added to an existing program, we need to add a new instrument specification and add a new query method to inventory, which does not seem easy to change! It seems that we still ha
Count the 24-point program: process-oriented and object-oriented C ++-general Linux technology-Linux programming and kernel information. The following is a detailed description. 1. Overview Given four integers, each digit can only be used once. Any +-*/() is used to construct an expression, and the final result is 24,
In fact, the overload of the constructor is nothing more than implementing the definition of several functions, and then specifying different parameters. The simplicity is not reflected in the definition, but in the use. Only one function name is called, you can perform different operations. Pointer in Object-Oriented: Pointer to the object; Time * PT Time T1
Different people refer to different meanings when talking about Object-Oriented Programming (OOP. Some people think that any application that uses a graphical interface is object-oriented. Someone uses it as a term to describe a special inter-process communication mechanism. Some people use this word in a deep sense. T

Object-oriented design is divided into two stages, namely high-rise design and low-level design High-level design The overall model of development software for the development of the system in the high-rise
The goal of service-oriented design is to divide the business system into independent computing units, like CPUs. These independent computing units are services, and most of them are used to implement services, another service is used to assemble these business services, which is a workflow service. The core value of a service is autonomy and autonomy. A service is like an operational unit. This is a metap
These days re-read the "Big Talk design mode", found that there are different sentiment, but also on the internet to find the "Agile software Development-principles, patterns and practices," a book, the preface of the book there is a paragraph I think very reasonable: "Beautiful things than ugly to create cheaper and faster." "The design of a software is not abou

student and could be used to solve a multi-dimensional equation immediately. Later, structured programming was developed to split the code into multiple modules, this enhances code reusability and facilitates debugging and modification, but the structure is much more complex. The earliest programming method was process-oriented. It was very intuitive for beginners to understand quickly. Later, with the object
Become a senior architect first to understand the design pattern, before understanding, to understand the design principles, the original I ate this loss, a long time to someone asked me design principles, I am a dazed, not only design
People often talk about "object-oriented design", as if it is something highly advanced and proud of object-oriented design. Object-oriented
[Favor composition over inheritance] Combination 1. (object) combination is a method of reusing new functions by creating an object that combines other objects. 2. delegate the function to a combined object to obtain the new function. 3. Sometimes it is called "aggregation" or "inment", although some authors give special meanings to these terms 4. For example: A
Interface An interface is a group of methods that can be called by another object. An object can have multiple interfaces. Type is a special interface of an object Different objects can have the same type. An object can have multiple types. An object can
