THE HISTORY OF PROGRAMMING: FOCUS ON C++ UNDERSTANDING THE EVOLUTION AND IMPACT OF C++ Wendell J. Del Campo University of Southeastern Philippines  1 INTRODUCTION Overview: Introduction to programming languages and their evolution. Focus on C++: Exploring the origins, development, and significance of C++ in the programming world. Importance: C++ has played a crucial role in software development, influencing modern programming languages and paradigms. University of Southeastern Philippines  1 THE BIRTH OF PROGRAMMING LANGUAGES Early Programming: Assembly Language: The first low-level language that allowed programmers to write machine instructions in a human-readable format. FORTRAN (1957): One of the first high-level programming languages, designed for scientific computing. ALGOL (1958): Introduced the concept of structured programming, influencing many later languages. University of Southeastern Philippines  1 THE BIRTH OF PROGRAMMING LANGUAGES The Need for High-Level Languages: To simplify coding, improve readability, and enhance productivity. University of Southeastern Philippines  1 THE GENESIS OF C (1969-1973) Creation of C: Dennis Ritchie developed it at Bell Labs between 1969 and 1973. Purpose: Designed for system programming, particularly for writing operating systems. UNIX Connection: C was used to rewrite the UNIX operating system, contributing to its widespread adoption. University of Southeastern Philippines  1 THE GENESIS OF C (1969-1973) Key Features of C: Efficiency: Close to machine-level code, making it fast and efficient. Portability: Code written in C can be run on different hardware with minimal modification. Structured Programming: Support for functions, loops, and conditionals to create well-organized code. University of Southeastern Philippines  1 THE DEVELOPMENT OF C++ (1979-1985) Bjarne Stroustrup's Vision: Origin: C++ was developed by Bjarne Stroustrup at Bell Labs in 1979 as an extension of C. Objective: To add object-oriented features to C while retaining its efficiency and flexibility. Initial Name: Originally called "C with Classes." University of Southeastern Philippines  1 THE DEVELOPMENT OF C++ (1979-1985) First Release: 1983: The language was officially named C++. 1985: The first commercial release of C++ and the publication of "The C++ Programming Language" book by Stroustrup. University of Southeastern Philippines  1 KEY FEATURES OF C++ Object-Oriented Programming (OOP): Classes and Objects: Introduced the concept of defining data structures as classes and creating objects as instances of these classes. Inheritance: Allows new classes to inherit properties and methods from existing classes, promoting code reuse. University of Southeastern Philippines  1 KEY FEATURES OF C++ Polymorphism: Enables objects to be treated as instances of their parent class, enhancing flexibility. Encapsulation: Ensures that an object's data is hidden and only accessible through defined methods. University of Southeastern Philippines  1 KEY FEATURES OF C++ Efficiency: Low-Level Manipulation: C++ retains the ability to perform low-level memory manipulation through pointers and direct access to hardware. Templates: Introduced generic programming, allowing functions and classes to operate with any data type. Compatibility: Fully compatible with C, allowing C programs to be compiled and run with C++ compilers. University of Southeastern Philippines  1 EVOLUTION OF C++ C++98 (1998): First ISO Standard: C++ was standardized by the International Organization for Standardization (ISO) in 1998. New Features: Added features like the Standard Template Library (STL), namespaces, and exceptions. University of Southeastern Philippines  1 EVOLUTION OF C++ C++03 (2003): Minor Revisions: Focused on bug fixes and minor improvements to the C++98 standard. C++11 (2011): Major Update: Introduced features like auto keyword, lambda expressions, smart pointers, and improved multithreading support. University of Southeastern Philippines  1 EVOLUTION OF C++ C++14 (2014) and C++17 (2017): Incremental Improvements: Continued to refine and expand the language, adding features like constexpr, structured bindings, and filesystem support. University of Southeastern Philippines  1 EVOLUTION OF C++ C++20 (2020): Modern Enhancements: Introduced concepts, ranges, coroutines, and more, making C++ more expressive and safer. C++23 and Beyond: Ongoing Evolution: The language continues to evolve with community input and emerging computing needs. University of Southeastern Philippines  1 IMPACT OF C++ ON PROGRAMMING Widespread Use: Systems Programming: Used for developing operating systems, compilers, and embedded systems. Game Development: Preferred for performance-critical game engines like Unreal Engine. High-Performance Applications: Used in applications requiring efficient memory and processing management, such as financial systems and simulation software. University of Southeastern Philippines  1 IMPACT OF C++ ON PROGRAMMING Influence on Other Languages: Java: Borrowed many object-oriented concepts from C++. C#: Developed by Microsoft with C++ and Java influences. Modern C++: Continues to influence new languages and paradigms, such as Rust and Swift. University of Southeastern Philippines  1 CHALLENGES AND CRITICISMS Complexity: Steep Learning Curve: The combination of low-level features and object-oriented programming makes C++ challenging for beginners. Potential for Errors: Manual memory management and pointer arithmetic can lead to bugs and security vulnerabilities. University of Southeastern Philippines  1 CHALLENGES AND CRITICISMS Comparison with Other Languages: Java and Python: Offer easier learning curves and automatic memory management, making them popular for rapid development. C#: Provides a more modern, streamlined object-oriented experience while retaining some of C++'s power. University of Southeastern Philippines  1 MODERN USAGE OF C++ Continued Relevance: Cross-Platform Development: C++ remains a top choice for applications that need to run on multiple platforms. Performance-Critical Applications: Still preferred in domains where performance is critical, such as gaming, simulations, and real-time systems. Embedded Systems: Widely used in embedded systems due to its efficiency and control over hardware. University of Southeastern Philippines  1 MODERN USAGE OF C++ Adoption in New Fields: AI and Machine Learning: Leveraged in high-performance libraries and frameworks (e.g., TensorFlow, PyTorch backend). Cloud Computing: C++ is used in the development of cloud infrastructure and services, requiring robust and efficient code. University of Southeastern Philippines  1 FUTURE OF C++ Ongoing Development: Continuous evolution of the language with regular updates, ensuring it stays relevant. Community Support: A strong community and industry backing keep C++ at the forefront of programming languages. Adoption of Modern Practices: Emphasis on safer and more expressive features while retaining the power and flexibility of the language. University of Southeastern Philippines  1 CONCLUSION Summary: C++ has been a pivotal language in the history of programming, combining the power of C with modern programming paradigms. Final Thoughts: Its impact on software development is undeniable, and its ongoing evolution ensures it remains a vital tool for future generations of programmers.
