C++ Introduction

What is C++? 

  • C++ is a general-purpose object-oriented programming (OOP) language, developed by Bjarne Stroustrup 
  • It is an extension of the C language
  • Initially, the language was called "C with classes" as it had all the properties of the C language with an additional concept of "classes." However, it was renamed C++ in 1983.


Key Features of C++:

Object-Oriented Programming (OOP): C++ supports object-oriented programming concepts such as classes, objects, encapsulation, inheritance, polymorphism, etc. This enables modular, reusable, and maintainable code.

Compiled Language: C++, like C, is a compiled language, meaning that any C++ source code must be turned into machine code before execution.

Cross-Platform: C++ programs can be built to operate on multiple platforms with little or no modification, making it a versatile language for a wide range of operating systems and hardware architectures.

Rich Standard Library: C++ includes a comprehensive standard library with many functions and classes for activities such as file I/O, string manipulation, mathematical operations, and more.

Performance: C++ is renowned for its effectiveness and speed. It gives developers fine-grained control over system resources by enabling low-level data manipulation and features like manual memory management and pointers.

Compatibility with C: Because C++ and C are backward compatible, most C code may be readily incorporated into C++ systems. Developers can now take advantage of pre-existing C codebases and libraries.

Applications of C++:

Game Development: C++'s efficiency and speed make it a popular choice for game developers. It is frequently used in the creation of powerful gaming engines and titles.

User-Interface Applications: C++ is used in the development of several graphic user interface (GUI) programs, such as Adobe Photoshop, due to its ability to process graphic data quickly.

Web-Browsers: Web browsers are developed using C++; one well-known example of a project using C++ is the Chromium browser from Google.

Database Applications: Because C++ is used to write database management systems like MySQL, data processing and manipulation are made more efficient.

Operating Systems: An essential component in the creation of operating systems is C++. For example, C++ is used extensively in the development of Windows features.
