Q31.
What is the advantage of .NET and its programming languages' ability to interoperate?

a.

They allow for explicit deletion of objects.

b.

They allow for multiple levels of inheritance.

c.

They allow for seamless inheritance between programs written in different languages.

d.

They allow for unsafe typecasting.

Discuss
Answer: (c).They allow for seamless inheritance between programs written in different languages. Explanation:Because of the presence of metadata that accurately describes an executable, programs can interoperate at the object level regardless of the programming language they are created in, allowing for seamless inheritance between programs written in different languages.
Q32.
What is the Common Type System (CTS)?

a.

A system that governs the organization of data types in .NET programs

b.

A system that governs the organization of data types in Java programs

c.

A system that governs the organization of data types in Python programs

d.

A system that governs the organization of data types in PHP programs

Discuss
Answer: (a).A system that governs the organization of data types in .NET programs Explanation:The Common Type System (CTS) governs the organization of data types in .NET programs.
Q33.
What are the two fundamental data types in .NET programs?

a.

a.

The process of converting a value type data structure into a reference type object

b.

The process of converting a reference type data structure into a value type object

c.

The process of allocating an object on the stack

d.

The process of allocating an object on the heap

Discuss
Answer: (a).The process of converting a value type data structure into a reference type object Explanation:Boxing is the process of converting a value type data structure into a reference type object.
Q36.
What is unboxing?

a.

The process of converting a value type data structure into a reference type object

b.

The process of converting a reference type data structure into a value type object

c.

The process of allocating an object on the stack

d.

The process of allocating an object on the heap

Discuss
Answer: (b).The process of converting a reference type data structure into a value type object Explanation:Unboxing is the process of converting a reference type data structure into a value type object.
Q37.
Why is boxing needed?

a.

To check the object's type in runtime

b.

To duplicate the object in question

c.

To modify the object while it is in object form

d.

To free the heap block

Discuss
Answer: (a).To check the object's type in runtime Explanation:Boxing is needed so that a method can check the object's type in runtime.

a.

1

b.

2

c.

3

d.

4

Discuss
Answer: (b).2 Explanation:.NET programs essentially have two compilation stages.
Q40.
What is the role of the just-in-time compiler in .NET execution?

a.
