Object-Oriented	No built-in support	Yes (classes, inheritance, polymorphism)
Standard Library	Limited, focuses on basic functionalities	Extensive, including containers, algorithms, and input/output streams
Error Handling	Primarily through return codes	Exceptions
Abstraction	Limited	High, supports complex abstractions through classes and templates
Use Cases	System programming, embedded systems, performance-critical applications	Game development, high-performance computing, large-scale applications, operating systems, and more
Complexity	Simpler syntax but requires meticulous memory management and manual error handling	More complex syntax with advanced features, but provides tools for safer and more efficient coding
Learning Curve	Steeper initial learning curve due to manual memory management, but easier to grasp the overall language structure compared to C++	More gradual initial learning curve, but requires significant effort to master advanced concepts and best practices
Community Support	Mature with extensive documentation and resources, but may lack modern tooling and frameworks	Vibrant with active development and a wide range of libraries and frameworks, but can be overwhelming for beginners due to the complexity and rapid evolution of the language

1.2 Key Differences That Impact Learning
