C++ is a statically typed, compiled, general, case-sensitive, and irregular programming language that supports procedural programming, object-oriented programming and generic programming.
C++ is considered to be an intermediate language, which combines the characteristics of high-level and low-level languages.
C++ was designed and developed by Bjarne Stroustrup in 1979 at Bell Labs in Murray Hill, New Jersey. C++ further expanded and improved the C language, originally named C with classes, and later renamed C++ in 1983.
C++ is a superset of C. In fact, any legal C program is a legal C++ program.
Note: Programming languages that use static types perform type checking at compile time, not at runtime.
C++ fully supports object-oriented programming, including four major features of object-oriented development:
Standard C++ consists of three important parts:
- The core language provides all building blocks, including variables, data types and constants, etc.
- The C++ standard library provides a large number of functions for manipulating files, strings, etc.
- The Standard Template Library (STL) provides a large number of methods for manipulating data structures.
The ANSI standard is to ensure the portability of C++-the code you write can be compiled on Mac, UNIX, Windows, and Alpha computers.
Since the ANSI standard has been used stably for a long time, all major C++ compiler manufacturers support the ANSI standard.
The key to learning C++ is to understand the concepts and not to delve too deeply into the technical details of the language.
The purpose of learning a programming language is to become a better programmer, that is, to design and implement new systems more efficiently, and to maintain old systems.
C++ supports multiple programming styles. You can use the programming style of Fortran, C, Smalltalk, etc. to write code. Each style can effectively ensure runtime efficiency and space efficiency.
Use of C++
Basically, programmers in every application field use C++.
C++ is usually used to write device drivers and other software that directly manipulates hardware that requires real-time performance.
C++ is widely used in teaching and research.
Anyone who uses an Apple computer or a Windows PC is indirectly using C++, because the main user interface of these systems is written in C++.
