C C++: The Art and Engineering of Programming Languages.
I. Introduction. C and C++ are two very powerful and commonly used programming languages, each with its own unique features and use cases. C is known for its efficiency and flexibility, and is often used to develop low-level system software and embedded systems; C++, on the other hand, adds object-oriented features to C and is widely used in game development, desktop applications, mobile applications, and other fields. This article will delve into the features and applications of C and C++ in order to help readers better understand and master both languages.
2. C language: the cornerstone of low-level programming.
Brief introduction. C language is a general, procedural computer programming language, which is widely used in system application software, operating systems, embedded systems and other fields. It was created by Dennis MRitchie was designed in 1972 to develop components for the operating system on Unix systems.
Characteristic. The C language has the following features:
Procedural language: C is a structured programming language that supports basic control structures such as sequence, selection, and looping.
Low-level language: C is considered a low-level language because it allows programmers to access memory directly, perform bit operations, etc.
Static type: C is a statically typed language, which means that the type of a variable cannot be changed after it has been declared.
Compiled language: C language needs to be compiled into machine code before it can be executed.
Apply. C language is widely used in the development of operating systems, compilers, embedded systems, and other fields. Many well-known software and operating systems, such as Linux and UNIX, are written in C.
Example**. Here's a simple C program for printing "Hello, World!."”：
cCopy**.
3. C++: Object-oriented programming language.
Brief introduction. C++ is an object-oriented programming language developed by Bjarne Stroustrup in 1983 on the basis of the C language. It is widely used in game development, desktop applications, mobile applications, and other fields.
Characteristic. C++ has the following features:
Object-oriented: C++ supports object-oriented features such as classes, objects, inheritance, and polymorphism.
Statically typed: Like C, C++ is a statically typed language.
Compiled language: C++ also needs to be compiled into machine code before it can be executed.
Apply. Due to its object-oriented nature, C++ is widely used in game development, desktop applications, mobile applications, and other fields. Many well-known games and software are developed using C++.
Example**. Here's a simple C++ program for calculating the sum of two numbers:
