Programming Language Related Short Questions and Answers
What are the differences between C, C++ and C#? (C vs C++ vs C#)
Ans : C, C++, and C# are all popular programming languages, but they have some key differences:
- Level: C is a low-level language, C++ is a mid-level language, and C# is a high-level language. This means C provides more control over hardware but requires more code, while C# is more abstract and easier to use.
- Memory Management: C++ requires manual memory management, which can be error-prone. C# has automatic garbage collection, which simplifies memory management.
- Compilation: C and C++ compile directly to machine code, while C# compiles to an intermediate code that’s then executed by the Common Language Runtime (CLR). This makes C# more portable.
- Use Cases: C is often used for system programming and embedded systems. C++ is used for performance-critical applications, game development, and system programming. C# is popular for developing Windows applications, web services, and games.
