The main object of this article is CPU and memory. Why learn C language before must understand, because C language is very close to the underlying principle of the language, understand the principle of CPU and memory, to learn C language has a great help.In fact, I am a personal advocate of computer science should first learn the

application-layer language (bottom-level is C/S, WINAPI, COM Ole VB, DirectX, or a custom library on a mono project), and . NET -based IL CLR Runtime Libraries, and application sets, the application domain is a great innovation for application compilation and application composition Systems , but the pros also bring drawbacks. Low-level or real-time high-performance applications that are difficult to replace c
distributions are often used, and other distributions include bernoulli_distribution,exponential_distribution and chi_distribution. Detailed descriptions can be found in the C + + programming Language. The return value of the integer distribution is the closed interval [A:B], and the return value of the real (floating-point) distribution is the open interval [a:b].By default, each time the program runs, the generator (except Random_device) produces t
concise than the description in natural language (English, Chinese). This applies in many cases, and the purpose of the programming language is to describe our thoughts in a more concise and accurate manner.The method of function definition is described as follows:type function name (parameter table) function bodyWhere the type is the return value type of the function, the function name is the token of the function, in parentheses is the parameter table, and the function body is the statement t
operator:First, the destructor of the vector is activated; The constructor activates the destructors for these elements (if they have destructors), and then releases the memory used by those elements.Then, release the memory used by the vector.Type blending: untyped pointers and pointer type conversionsWe are very close to the hardware level when using pointers to free-space allocation arrays. Basically, we map the operation of pointers (initialization, assignment, * and []) directly to machine
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 mode? And do not know the principle of design is like writing calligraphy, in italics is the founder, Vertical Road has vertical dew, etc., the official script has a silkworm
, including the parent class of the exported class, regardless of the order or quantity of the definition, and do not move all virtual functions, either in order or in quantity.When exporting a class design, remember not to export anything other than a function.It is recommended that when you publish the DLL of the exported class, you redefine the declaration of a class, which can be listed in the declaration of the class, regardless of the member variables in the original class, as in the follo
needWorkaround:1, use the delegate to separate the interface. 2, using multiple inheritance to separate the interface. 3. Split the bloated interface I into separate interfaces, and Class A and Class C are dependent on the interfaces they need. That is, the principle of interface isolation.Summary: We in the code writing process, the use of interface isolation principle, must be moderate, the interface design is too large or too small is not good.

object-oriented design process, under specific scenarios, and between classes and communicating with each other.? A deep understanding of object-oriented is the basis of learning design patterns, mastering certain object-oriented design principles can grasp the essence of object-oriented design pattern, and thus realize the flexible use of design patterns.? Three basic object-oriented design principles– Pr

Key System PrinciplesR900: Increment and decrement operations cannot be used as sub-expressions.Example:int x=v[++i]; Violate++i;int x=v[i]; That's rightCause: It may be missed out.R901: Code should not rely on precedence rules under algorithm expression precedence.Example:X=a*b+c
In this article we will talk about the seven principles, namely: single duty, Richter replacement, Dimitri Law, Reliance reversal, interface isolation, synthesis/aggregation principle, open-closed .

This is an excellent textbook for beginners.
Among the programming books I have read, this is the second entry book suitable for beginners who have no programming experience (the previous book is called "C language parsing tutorial"). However, this book has not yet heard of related exercises and questions, so it cannot be regarded as a completely self-tau
