Key Differences Between class (C++/Java) and struct (C#) Feature class in C++/Java struct in C# Type Reference type Value type Memory Storage Stored in heap (reference) Stored in stack (value) Default Access Modifier Private (C++), Public (Java) Public Inheritance Support Supports inheritance Limited inheritance (cannot inherit from a class) Garbage Collection Yes (Java), Optional in C++ No (automatically deallocated when out of scope) Performance Slightly slower (heap allocation) Faster for small data structures (stack allocation) Best Use Cases Large, complex objects, need polymorphism Small, lightweight data structures like coordinates or points Summary: Use class when you need object-oriented features like inheritance, polymorphism, and heap allocation. Use struct in C# for small, simple data types that don’t need inheritance and benefit from stack allocation. read less
