C++is a powerful and widely used programming language, and for those who want to delve deeper into programming and algorithms, mastering C++is an important milestone. This article will take you step by step to understand the basic knowledge of C++programming, and introduce some common algorithms and programming skills to help you get started with C++algorithms.

1. What is Programming?

Programming is the process of using a specific programming language to write a series of instructions or code to tell a computer to perform specific tasks or solve problems. It aims to translate abstract ideas and concepts into instructions that a computer can understand and execute. Programming is used to develop various software applications, websites, games, etc., and allows people to leverage the power of computers for automation, data processing, and innovation.

Here are some important milestones in the development of programming. Interested parties can take a look:

Mechanical computing equipment: In the late 19th and early 20th centuries, a series of mechanical computing equipment emerged, such as differential machines and analytical machines. These mechanical devices require physical settings to perform computational tasks, rather than programming.

Relay and electronic tube: In the mid-20th century, the invention of relays and electronic tubes made computers more reliable and efficient. These devices are capable of performing logical and arithmetic operations, but programming is still done in physical ways (such as patch panels, punched paper tapes).

Binary systems and assembly languages: The popularity of binary systems has enabled computers to represent and process information in digital form. With the introduction of binary systems, assembly language has also emerged. Assembly language uses mnemonics and symbols to represent machine instructions, simplifying the programming process.

Advanced programming languages: In the late 1950s and early 1960s, advanced programming languages began to emerge. These languages (such as Fortran, COBOL, and ALGOL) enable programmers to write code in a more human like manner, thereby improving the readability and maintainability of programming.

Operating System: With the development of computers, the operating system has become a key component for managing computing resources and providing programming interfaces. The operating system enables programmers to use higher-level abstractions to write applications without directly dealing with underlying hardware.

Object oriented programming: In the 1970s and 1980s, object-oriented programming (OOP) became popular. The idea of OOP is to encapsulate data and operations in objects, providing a more flexible and modular programming approach.

Internet and Web programming: With the popularization of the Internet, Web programming has become an important field. Technologies such as HTML, CSS, and JavaScript enable devel
