Key differences between C and C#

Characteristic C C#
Type Compiled, statically-typed programming language Compiled to intermediate language (IL), statically-typed programming language
Memory Management Manual (using malloc/free) Automatic (Garbage Collection)
Platform Dependency Platform-dependent (compiled to machine code) Platform-independent (runs on .NET runtime, including .NET Core and Mono)
Syntax and Features Procedural programming, supports pointers, no built-in support for OOP Object-oriented programming, supports properties, events, delegates, LINQ, async/await
Compilation Compiled to native machine code Compiled to Intermediate Language (IL), which is then JIT-compiled by the .NET runtime
Standard Library Standard C Library (stdlib) for basic functions Extensive .NET Standard Library with support for a wide range of applications
Object-Oriented Programming Does not support object-oriented programming natively Fully supports object-oriented programming
Concurrency Requires libraries for multithreading support (e.g., pthreads) Built-in support for multithreading and asynchronous programming (Task Parallel Library, async/await)
Use Cases System software, embedded systems, real-time applications Web applications, enterprise software, desktop applications, game development with Unity
Performance Typically faster, closer to hardware Generally slower due to JIT compilation and garbage collection, but optimized for productivity and ease of use
