	Short int
	enum
	static int

Question 2

In C# Conversion from value type to reference type is known as

	Unboxing
	Boxing
	Type casting
	None of the above

Question 3

	Reference Type Assignment
	Value Type Assignment
	Object Type Assignment
	Pointer Type Assignment

Question 6

Which of the following are similar to classes, define a set of properties, methods, and events, but unlike classes, they do not provide implementation. They are implemented by classes, and defined as separate entities from classes.

	Functions in C#
	Structures in C#
	Interfaces in C#
	Objects in C#

Question 7

What allows a change to the implementation of a base class method in a derived class? Furthermore the virtual and override keywords play a vital role in this objective.

	Operator overriding
	Function overloading
	Method overriding
	Method overwriting

Question 8

Which keyword works like a cast operator except one difference is that it results in a null reference if cast fails and does not generate an exception.

	is
	like
	as
	while

Question 9

Have a look at the following code and choose the option which best describes it:

public static Vector operator +(Vector lhs, Vector rhs)
{
Vector result = new Vector(lhs);
result.x += rhs.x;
result.y += rhs.y;
result.z += rhs.z;
return result;
}

	Method overriding in C#
	Function overloading in C#
	Function Overriding in C#
	Operator Overloading in C#

Question 10

Consider a situation in which we want to call a method in our function ABC() but we don’t know the method until runtime; in this case what will we do?

	We will pass pointer to the function
	We will pass reference to the function
	Delegate at runtime
	a and b are correct

Question 11

If a delegate wraps around more than one method such a delegate is known as

	Delegate casting
	Multi level delegates
	Multicast delegate
	None of the above

Question 12

Constraints help us defining certain rules for the types we pass in. Please look at the constraint below and choose which kind of constraint it is:

public class Dictionary where K : class {}

	Reference type constraints
	Simple Derivation Constraint
	New() Constructor Constraint
	Value type Constraint
