c++ learning route

1. Elementary entry stage

Data types, variables, memory layout, pointer basics;

String, one Dimensional array, two-dimensional array;

First-level pointer, second-level pointer, third-level pointer, N-level pointer concept, pointer array and array pointer;

Use of structures and files;

Encapsulation and design of dynamic libraries;

Function pointer callback function.

Object-oriented programming ideas;

Class encapsulation, construction and destruction, static members, object management;

Class construction (parameterized constructor, parameterless construction , copy construction, default constructor) and destruction;

Object dynamic management, friend functions, friend classes, operator overloading;

C compiler object management model analysis;

Dynamic management of class objects (new/delete);

Friend functions and friend classes;

Operator overloading (unary operator, binary operator, difficulty in operator overloading, Operator overloading in project development);

Class inheritance, multiple inheritance and its ambiguity, virtual inheritance;

Polymorphism (concept, meaning, principle analysis, polymorphic cases);

Virtual functions, pure virtual functions, abstract classes (cases of abstract class programming ideas);

Function templates, class templates, template inheritance;

C type conversion;

C Input and output stream (standard I/O file I/O character stream I/O);

C Exception handling (exception mechanism, exception type, exception variable, exception hierarchy, standard Exception library);

2. IDE development tools

such as Windows platform VC series: VC 6.0 (relatively old);

Visual Studio2013, Visual Studio2015;

The XCode series for the Mac platform, as well as CodeBlock, also comes with some common settings for advanced editors Notepad, EditPlus, UE and other development tools and the use of some common shortcut keys.

3. Development advanced

1. STL

STL = Standard Template Library, that is, the standard template library. This is a great tool for improving development efficiency. By studying this stage, you should master generic programming skills, understand the application mode of container classes in C language, and be proficient in the use of all STL classes.

2. Design pattern

The most important factor that determines the success or failure of a project is the overall design of the project. Through this stage of study, you can master an important part of object-oriented programming, which is the key to coding before coding. The skill of modeling lies. Singleton mode; factory mode; agent mode; iteration mode, etc.

3. Data structure basics

This is the most important part to learn in all programming languages ​​and one of the foundations of program composition.

Sequential storage, chained storage, circular linked list;

Double linked list, stack (sequential and chained), queue (sequential and chained);

Application of stack , basic concepts of trees and traversal, binary trees;

Sorting algorithm, merge algorithm, selection, insertion, fast, Hill.

4. UI interface development

Master the QT class library architecture and graphical interface development model;

Master QT development skills, message mechanism, and graphics processing;

Master QT network programming, UDP, TCP usage;

Master QT file processing methods, serialization;

Master QT under different platforms of windows, linux, ios, android transplantation technology.

5. UBIX/LINUX network server

Master the Unix/Linux platform development method;

Proficient in using system calls;

Proficient in Unix/ Linux memory management, process, thread scheduling;

Familiar with network server development methods, proficient in writing TCP, UCP network service programs;

Master the use of synchronous/asynchronous IO models in network programming.

6. Database development

Master the practical skills of SQL language. How to use Oracle and MySQL databases.

4. Advanced Development

1. The knowledge and skills required for software development work at this stage are relatively difficult. Senior software engineers need to have coding proficiency and standardization. Certain requirements;

2. Have certain project capabilities (including debugging capabilities, document writing capabilities, testing capabilities, etc.) and comprehensive technical qualities (including understanding of software life cycle, understanding of design patterns, essential Industry knowledge and experience, etc.);.

3. Understand the mainstream back-end technology and front-end and back-end collaboration methods, and be able to understand the entire life cycle of the project from a global perspective.
