Introduction
C++ is a high-level, object-oriented programming language developed by Bjarne Stroustrup. It is widely used for software development, game development, and operating system programming. With its clean and efficient code, C++ is suitable for large-scale applications. This tutorial covers all the basic and advanced topics of C++, including C++ basics, functions, classes, and STL concepts.
What is C++?
C++ is a popular cross-platform programming language used to create high-performance applications such as operating systems, games, and e-commerce software. Developed as an extension of the C language, C++ offers a high level of control over system resources and memory.

Applications of C++
Here are some real-world applications of C++:
Operating Systems
C++ is extensively used in developing operating systems. Major parts of Mac OS X and Microsoft's software, such as Windows and Office, are written in C++.
Games
C++ is the go-to language for game development. It allows developers to create complex 3D games, multiplayer games, and more. Popular game engines like Unreal Engine are built using C++.
Web Browsers
Many web browsers, including Mozilla Firefox and Google Chrome, are developed using C++. C++ provides the necessary speed and efficiency required for browser development.
Compilers
Compilers for various programming languages, including C and C++, are built using C++. Its low-level nature allows for efficient compilation and optimization.
Embedded Systems
C++ is widely used in embedded systems development, such as smartwatches and medical equipment. Its ability to manipulate system resources makes it ideal for low-level programming.
FAQs on C++
What is the difference between C++ and C?
C++ is an extension of the C programming language. While both languages share similarities, C++ introduces object-oriented programming concepts and additional features.
C++ offers more control over system resources, supports classes and objects, and provides features like inheritance and polymorphism. On the other hand, C is more procedural and lacks these object-oriented features.
What are the differences and similarities between C++ and Java?
C++ and Java are both object-oriented programming languages, but they have some differences:
- Inheritance: C++ supports multiple inheritance, while Java supports single inheritance.
- Memory Management: C++ requires manual memory management, while Java has automatic garbage collection.
- Exception Handling: C++ uses try-catch blocks for exception handling, while Java has built-in exception handling mechanisms.
- Performance: C++ is typically faster than Java due to its closer-to-hardware nature.
- Templates vs Generics: C++ uses templates for generic programming, while Java uses generics.
Despite these differences, both languages are widely used and have large communities of developers.
Can C++ be used for competitive programming?
C++ is a popular choice for competitive programming due to its efficiency and flexibility. It offers features like fast I/O, STL algorithms and data structures, and a wide range of libraries. Learning C++ for competitive programming can give you an edge in solving complex problems efficiently.
