Question 1

Which of the following statements are correct about exception handling in C#.NET?1 If an exception occurs then the program terminates abruptly without getting any chance to recover from the exception. 2 No matter whether an exception occurs or not, the statements in the finally clause (if present) will get executed.3 A program can contain multiple finally clauses.4 A finally clause is written outside the try block.5 Finally clause is used to perform cleanup operations like closing the network/database connections.
A)1 only
B)2 only
C)2 and 5 only
D)3 and 4 only

Accepted Answer

2 and 5 are correct. The finally block always executes when the try block exits, ensuring cleanup operations like closing connections are performed. Statement 1 is incorrect because C#.NET provides try-catch blocks to handle exceptions and prevent abrupt termination. Statements 3 and 4 are incorrect because a finally clause is associated with a try block and cannot exist independently or in multiples for a single try block.

Question 2

______ parameters are used to pass results back to the calling method.
A)Input
B)Reference
C)Value
D)Output

Accepted Answer

Output parameters are specifically designed to pass results back to the calling method, allowing the method to return multiple values.

Question 3

The formal-parameter-list is always enclosed in _______.
A)Square
B)Semicolon
C)Parenthesis
D)Colon

Accepted Answer

The formal-parameter-list in programming languages, such as C, C++, Java, and many others, is always enclosed in parentheses. This is a standard syntax used to define parameters that a function or method can accept.

Question 4

_______ variables are visible only in the block they are declared.
A)System
B)Global
C)Local
D)Console

Accepted Answer

Local variables are visible only within the block or function where they are declared, unlike global variables which are accessible throughout the entire program.

Question 5

C# does not support _____ constructors.
A)parameterized
B)parameter-less
C)Class
D)Method

Accepted Answer

The answer of C# does not support _____ constructors.
A)parameterized
B)parameter-less
C)Class
D)Method...

Question 6

A structure in C# provides a unique way of packing together data of ______ types.
A)Different
B)Same
C)Invoking
D)Calling

Accepted Answer

A structure in C# can pack together data of different types, allowing for the creation of a complex data type that aggregates elements of disparate types.

Question 7

Struct's data members are ____________ by default.
A)Protected
B)Public
C)Private
D)Default

Accepted Answer

Struct's data members are private by default because they are only accessible within the struct itself.

Question 8

A _______ creates an object by copying variables from another object.
A)Copy constructor
B)Default constructor
C)Invoking constructor
D)Calling constructor

Accepted Answer

A copy constructor is a special constructor in a class that is used to create a new object as a copy of an existing object. This involves copying the values of all variables from the object being copied.

Question 9

The methods that have the same name, but different parameter lists and different definitions is called______.
A)Method Overloading
B)Method Overriding
C)Method Overwriting
D)Method Overreading

Accepted Answer

Method Overloading occurs when two or more methods in the same class have the same name but different parameters. This allows methods to perform similar functions but with different inputs.

Question 10

The C# provides special methods known as _____ methods to provide access to data members.
A)Loop
B)Functions
C)Methods
D)Accessor

Accepted Answer

C# provides special methods known as accessor methods to provide access to data members. These include getters and setters, which are used to retrieve and set the values of private fields, respectively.

Question 11

Storage location used by computer memory to store data for usage by an application is ?
A)Pointers
B)Constants
C)Variable
D)None of the mentioned

Accepted Answer

Variables are used by computer memory as storage locations to store data that can be accessed and manipulated by applications.

Question 12

Which of these can be overloaded?
A)Constructors
B)Methods
C)Both a & b
D)None of the mentioned

Accepted Answer

Both constructors and methods can be overloaded in many programming languages, including Java. Overloading allows multiple constructors or methods to have the same name with different parameters.

Question 13

Number of constructors a class can define of ?
A)1
B)2
C)Any number
D)None of the mentioned

Accepted Answer

A class in Java can define any number of constructors as long as they have different parameter lists. This allows for overloading constructors to initialize objects in different ways.

Question 14

Correct statement about constructors in C#.NET is ?
A)Constructor cannot be overloaded
B)Constructor allocate space for object in memory
C)Constructor are never called explicitly
D)Constructor have same name as name of the class

Accepted Answer

Constructors in C#.NET have the same name as the class they are defined in. This is a fundamental rule for constructors in C#.

Question 15

Constructors are used to
A)initialize the objects
B)construct the data members
C)both a & b
D)None of the mentioned

Accepted Answer

Constructors are used to initialize the objects and construct the data members.

Question 16

To overload a method which of the following statement is false?
A)If the return type is different methods are overloaded
B)Name of the overloaded method should be same
C)Type of the parameter should be different
D)Order of the parameter should be different if types are same

Accepted Answer

Overloading a method is based on changing the parameter list; the return type alone cannot be used to differentiate overloaded methods. If only the return type is different but the parameter list is the same, the methods are not considered overloaded.

Question 17

Which of the following statements is correct about constructors in C#.NET?
A)A constructor cannot be declared as private
B)A constructor cannot be overloaded
C)A constructor can be a static constructor
D)None of the mentioned

Accepted Answer

The answer of Which of the following statements is correct...

Question 18

What is return type of constructors?
A)int
B)float
C)void
D)None of the mentioned

Accepted Answer

Constructors do not have a return type, not even void. They are called automatically when an object is created and are used to initialize the object.

Question 19

Which method have same name as that of its class?
A)delete
B)class
C)constructor
D)None of mentioned

Accepted Answer

Constructors in object-oriented programming have the same name as the class they are in, and they are used to initialize objects of that class.

Question 20

Which of following statement are correct about functions?
A)C# allows a function to have arguments with default values
B)Redefining a method parameter in the method's body causes an exception
C)C# allows function to have arguments of private type
D)Omitting the return type in method definition results into exception

Accepted Answer

C# allows functions to have arguments with default values, enabling optional parameters.
