Question 1

The compiled version of a VC#.NET program will be in_______________.
A)Machine code
B)IL code
C)Byte code
D)None of these

Accepted Answer

The compiled version of a VC#.NET program will be in Machine code.

Question 2

The purpose of JIT compiler is to convert____________.
A)VC#.NET source code IL code
B)IL code to byte code
C)IL code to managed native code
D)None of these

Accepted Answer

B

Question 3

The Garbage Collection solves_____________.
A)Memory leakage problem
B)DLL hell problem
C)Both a & b
D)None of these

Accepted Answer

Garbage Collection is a form of automatic memory management that helps in reclaiming the memory allocated to objects that are no longer in use by the program, thus solving the memory leakage problem.

Question 4

The code that requires the CLR at runtime for the execution is known as the ________.
A)IL code
B)Managed code
C)Binary code
D)One of these

Accepted Answer

Managed code is executed by the CLR (Common Language Runtime) at runtime, providing services like garbage collection and exception handling.

Question 5

Which one of the following JIT compilers produce highly optimized code?
A)Econo JIT
B)Standard JIT
C)Pre JIT
D)None of these

Accepted Answer

Standard JIT (Just-In-Time) compiler is designed to produce highly optimized code, balancing the need for faster application execution without the extensive memory usage and startup time associated with pre-compilation methods like Pre-JIT. Econo JIT focuses on lower memory usage and faster startup at the expense of optimization, and Pre-JIT (also known as NGen or ahead-of-time compilation) focuses on pre-compiling assemblies to improve startup time but does not inherently produce more optimized code than Standard JIT.

Question 6

The VC#.NET language________________.
A)Solves the memory leakage problems.
B)Solves the DLL hell problems.
C)Has very good correspondence with the IL language.
D)All the above.

Accepted Answer

The answer of The VC#.NET language________________.
A)Solves the memory leakage problems.
B)Solves...

Question 7

Home page in VS.NET is also known as__________.
A)Default page
B)Start page
C)First page
D)Welcome page

Accepted Answer

The home page in Visual Studio .NET is referred to as the "Start page." This is the page that typically appears when you first launch the Visual Studio IDE, providing quick access to projects, news, and other resources.

Question 8

The ______________ enables to move through the code very quickly.
A)Class view window
B)Solution explorer window
C)Code window
D)none of these

Accepted Answer

The Code window is the primary area in an Integrated Development Environment (IDE) where developers write and review the code, allowing them to navigate through the code quickly.

Question 9

In VC#.NET project files are grouped into a _____________.
A)Workspace
B)Namespace
C)Solution
D)Package

Accepted Answer

In VC#.NET, project files are grouped into a "Solution." A solution acts as a container that can hold one or more projects, including class libraries, console applications, and other types of applications within Visual Studio.

Question 10

Which one of the following statements about code debugging is correct?
A)Debugger helps us to step through our code, one line at a time.
B)Breakpoints can be set by pressing F9 function key.
C)Breakpoints can be set by left-clicking in the left margin area at the line where we want to set the breakpoint.
D)a, b and c are correct.

Accepted Answer

The answer of Which one of the following statements about...

Question 11

The arrays involved in a jagged array_____________.
A)Should be of same size.
B)May be of different sizes.
C)Are not known as subarrays.
D)None of these.

Accepted Answer

Jagged arrays are arrays of arrays, where the inner arrays (subarrays) can be of different sizes. This flexibility allows for more complex data structures compared to multidimensional arrays, where all rows must have the same number of columns.

Question 12

The parameters of a method __________.
A)Help us to pass information to a method.
B)Help us to get information from a method.
C)Help us to pass information to and from a method.
D)None of these.

Accepted Answer

Parameters are used to pass information to and from a method.

Question 13

The ref type parameters are____________.
A)"Input only" parameters.
B)"Input / Output" parameters.
C)"Output only" parameters.
D)None of these.

Accepted Answer

The ref keyword in C# indicates that a parameter is passed by reference, allowing it to be both read and modified by the called method. This makes it an "Input / Output" parameter.

Question 14

The out type parameters can be used_______________.
A)Only to pass back a result to the calling functions.
B)Only to send information to the called function.
C)To pass data to the called method and receive information from the called method.
D)None of these.

Accepted Answer

Out parameters in C# are primarily used to return additional data from a method without using the method's return value. This allows a method to return multiple values.

Question 15

In case of the Params type parameter____________.
A)Only output can be sent.
B)The number of arguments is variable.
C)Both input and output can be handled.
D)None of these.

Accepted Answer

The Params keyword in C# allows a method to accept a variable number of arguments.

Question 16

An instance class member is referred by using the format____________.
A)Object name. Class member name.
B)Class name. Class member name.
C)Object name. Class member name or class name. class member name.
D)None of these.

Accepted Answer

An instance class member is accessed using the object name followed by a dot and the class member name.

Question 17

Overloaded constructors will have________.
A)Different names
B)Different parameter lists
C)Different return types
D)none of these.

Accepted Answer

Overloaded constructors must have different parameter lists to be distinguished from one another. This allows the compiler to know which constructor to call based on the arguments passed. The names of overloaded constructors are the same (as they are the name of the class), and constructors do not have return types.

Question 18

A static constructor_____________.
A)Is executed when the class is loaded.
B)Can be accessed through an object name.
C)Can be executed any number of times.
D)Can have its own destructor.

Accepted Answer

Static constructors are executed automatically when the class is loaded into memory before any instance of the class is created, ensuring that static fields are initialized. They cannot be called directly, do not have access modifiers, and are executed only once.

Question 19

A property________________.
A)Should have a get method.
B)Should have a put method.
C)Should have both get and put methods.
D)Should have either a get method or put method.

Accepted Answer

A property in programming typically should have a get method to retrieve the value of the property.

Question 20

An indexer________________.
A)Enables us to access a property through index.
B)Can have user-defined name.
C)Is identified by its name.
D)Cannot be overloaded.

Accepted Answer

Indexers enable access to elements in a class or struct that can be indexed in a manner similar to arrays, allowing for indexed property access. They cannot have user-defined names, are identified by the "this" keyword, and can be overloaded.
