What is .net? What is boxing , unboxing? Wha is constraints ? Explain oops?

Question

Accepted Answer

.NET is a software framework developed by Microsoft. Boxing and unboxing are operations to convert value types to reference types and vice versa.

Boxing is the process of converting a value type to an object type, which involves creating a new object on the heap and copying the value into it.
Unboxing is the process of extracting the value type from an object type, which involves casting the object to the appropriate value type and copying the value back to the stack.
Constraints in .NET are used to restrict the types that can be used as generic type arguments. They define requirements that a type must meet to be used with a generic type or method.
Object-Oriented Programming (OOP) is a programming paradigm that organizes software design around objects, which are instances of classes. It emphasizes encapsulation, inheritance, and polymorphism.

Accepted Answer

Boxing:- Boxing is the process of converting a value type variable(char, Int, etc) to a reference type variable(object) and value type variable always stored in stack memory and reference type variable are stored in heap memory.

Unboxing:- Unboxing is the process of converting a reference type variable into a value type variable.

Constraints:- Constraints are set or specific rules that inform to the compiler about capabilities a type must have.
