What is the difference between Class and Structure?

Following are the differences between Class and Structure :

• Structures are value types and classes are reference types. So structures are stored on stack and classes uses heap.
• Garbage collector terminated objects created from classes. Structures are not destroyed using Garbage collector.
• Structures do not require constructors while classes require. Usually classes have default parameter less constructors.
• Since structures not allow inheritance, therefore structures members cannot be declared as protected.
