C ++ Primer Plus Reading Notes, This article aims to record some key knowledge points in the fifth edition of C ++ Primer Plus for future reference. This article will be updated constantly ...... Chapter I. III 1. unsigned integers cannot store negative values. The advantage is that they can increase the maximum value that a variable can store. For example, if the short value range is-32768-32767, the value

C ++ primer (Chapter 2: variables and basic types) This is my summary of chapter 2 of c ++ primer, which is suitable for me. A small part of it is omitted without any mention, or something that is hard to remember. The layout is too hard, and the image format is put directly. It is directly attached from your oneNote. This layout can be changed again. Wait for the afternoon. It is not easy to summarize.

C ++ Primer Study Notes: Introduction to iterator, Station c In C ++ Primer (fifth edition), in example 3.4.1, a string vector named text is used to store the data in the text file and output the content in the text file. At the beginning, I wrote: # Include Error: Error: member reference base type 'const char 'is not a structure or union SetString text ("name ");ChangeConst vector No error occurs. No

What is a composite type in C + +?At first, you thought your custom class was a composite type. I checked the C + + primer to know that the composite type is not a class.In C + +, the type can be broadly divided into three typesFirst, built-in typesuch as int, char, float, unsigned and so on. Built-in types are the most basic types.Second, compound typeComposite types: Types defined by other types, using types defined by other types. There are three k

Smart pointers are obviously an attractive part of C ++ and must be mastered. I read C ++ primer, which focuses on the implementation of smart pointers. The book says: "HasPtr (Note: it is a custom smart pointer) has the same behavior as a normal pointer in other aspects. Specifically, when copying an object, the copy object and the original object will point to the same basic object. If a basic object is changed through a copy, the value accessed thr

C + + Primer Learning notes _17_ classes and Data Abstraction (3) _ Class scopeIntroduction:Each class defines its own new scope and unique type. Even though two classes have exactly the same list of members, they are different types. the members of each class differ from the members of any other class (or any other scope) .First, the name lookup in the scope of the class1) First, look for the name declaration in the block that uses the name. Consider

C + + Primer Learning Notes _15_ class and Data Abstraction (1) _ Class definition and declarationIn C + +, classes are used to define their own abstract data types. By defining types to correspond to the various concepts in the problem to be solved, we can make it easier to write, debug, and modify programs. You can make your own defined data types as easy and intuitive as the built-in types.Take a look at the Sales_item class:Class Sales_item{privat

The following is achieved by using C and C + + to implement a chain stack (linked list implementation), from which the idea of data encapsulation abstraction is realized:"C + + implementation"#include Operation Result:4 3 2) 1 0"C Language Implementation" #include Operation Result:4 3 2) 1 0The output is consistent, contrasting different ways of writing, you can experience the differences between the two languages.Reference:C + + Primer Fourth Editio

C + + Primer (Fifth edition) learning Note _1_ Standard Template Library-Quick StartWelcome to read the reference, if there are errors or questions, please leave a message to correct, thank youThe Standard Template Library (STL) provides three types of components: containers, iterators, and algorithms, all of which support generic program design standards.There are two main types of containers: sequential containers and associative containers. sequent

A: Preface This section, we need to stop our small game development, although it is not perfect now, is very simple, even there are bugs. But to get a better understanding of C #, it's time to delve into the basics.Of course, in fact, this section is still a bit difficult for beginners with 0 basic primer. Delegate and event, if only a general say, may be one or two words. However, our curriculum follows a principle: know it and know why. So, this sec

In the previous blog Windows Build Python development environment, Python primer to proficient [a] many friends mentioned that they want to use Visual Studio 2013/visual Studio Python to do the demo, here is a slightly, in fact, " Learning Python, it is recommended to use Pycharm,pycharm to set multiple IDE encodings, such as vs or Eclipse, to make it easier for most other languages to use the IDE's habits. This compatibility really does a good job. B

C++primer 18th. 1.2 In introducing the allocator class, an example of a vector modeled in the standard library was given. Feel the sample code is very good, but I found a bug, shared with everyone.According to the author's sample program, compile the program always in the Alloc.construct () function error, different IDE may be prompted by different reasons, I am undefined reference to ' vectorThink about it, it should be related to the static property

C # Basics Primer Eight Generics Generics in C # can pass a type as a parameter, that is, when creating a type, use a specific symbol, such as "T", as a placeholder instead of the actual type, and wait for the instantiation to be replaced with an actual type. public class Test Use generic types to maximize code reuse, protect types of security, and improve performance Methods that reduce the cost or risk of a cast or boxing
