C++ Tutorial Roadmap
Overview of C++
C++ is a powerful, high-performance programming language that supports procedural, object-oriented, and generic programming. It is widely used for system software, game development, competitive programming, and performance-critical applications.
Features of C++
- Object-oriented programming
- High performance and low-level memory control
- Support for generic programming using templates
- Rich Standard Template Library (STL)
- Backward compatibility with C
Difference Between C and C++
- C is procedural; C++ supports OOP
- C++ provides classes, objects, and templates
- C++ offers stronger type checking and abstractions
Basic Data Types
