“Implementing polymorphism and virtual functions in C++ for better code structure. Using GCC compiler.”Title: Notes on C++ Programming
1. Introduction to C++:
– C++ is a high-level programming language derived from C, with added features.
– Combines procedural and object-oriented programming paradigms.
– Widely used in system/application software, game development, embedded systems, etc.
2. Basic Syntax:
– Similar to C, includes data types, variables, control structures, functions, etc.
– Additional features like classes, objects, inheritance, polymorphism, etc.
3. Object-Oriented Programming (OOP) Concepts:
– Classes and Objects:
– Classes define blueprints for objects, encapsulating data and methods.
– Objects are instances of classes, representing real-world entities.
– Inheritance:
– Allows a class to inherit properties and behavior from another class.
– Supports the creation of hierarchical class structures.
– Polymorphism:
– Ability of objects to take multiple forms, achieved through function overloading and overriding.
– Encapsulation:
– Bundling data and methods within a class, hiding internal implementation details.
4. Pointers and Memory Management:
– Pointers facilitate dynamic memory allocation and manipulation.
– Essential for managing memory efficiently, but requires careful handling to avoid memory leaks and segmentation faults.
5. Standard Template Library (STL):
– Provides a collection of generic data structures and algorithms.
– Includes containers (vectors, lists, maps, etc.) and algorithms (sorting, searching, etc.).
– Boosts productivity and code reusability.
6. Exception Handling:
– Mechanism to handle runtime errors gracefully.
– Enables the separation of error-handling code from normal program logic.
– Uses try, catch, and throw keywords.
7. File Handling:
– Allows reading from and writing to files.
– Uses streams (ifstream, ofstream) to perform file operations.
– Facilitates input/output operations for persistent data storage.
8. C++11/14/17 Features:
– Modern C++ standards introduce new features like lambda expressions, auto keyword, smart pointers, etc.
– Enhances code readability, performance, and maintainability.
9. Compiler and Development Environment:
– Various compilers available (GCC, Clang, Visual C++, etc.).
– Integrated Development Environments (IDEs) like Visual Studio, Code::Blocks, and CLion offer comprehensive tools for C++ development.
10. Best Practices and Coding Guidelines:
– Follow naming conventions and coding standards for consistency.
– Use comments to document code and improve readability.
– Practice modularization and code reuse for maintainability.
11. Conclusion:
– C++ is a powerful and versatile programming language suitable for a wide range of applications.
– Understanding its core concepts and features is essential for writing efficient and maintainable code.
