Question 1

The name of the method,modifiers,return type,and the types of its formal parameters make up the signature of the method.

Accepted Answer

False

Question 2

A standard convention used by programmers for naming classes is to use an action verb phrase.

Accepted Answer

A standard convention used by programmers for naming classes is to use a noun or noun phrase, representing the class's purpose or nature. For example, "Employee" or "CustomerOrder".

Question 3

Methods may be defined in any order and placed anywhere in the file,in or outside of the class.

Accepted Answer

Methods must be defined within the class or object they belong to in most programming languages, and their placement order in the file does not typically affect their functionality, but they cannot be placed "anywhere" outside of their respective classes or objects.

Question 4

A standard convention used by C# programmers is to use Pascal case style for class,data member identifiers,and method identifiers.

Accepted Answer

In C#, the standard convention is to use PascalCase for class and method identifiers, but camelCase is typically used for data member identifiers (fields and properties may vary, with properties often using PascalCase).

Question 5

Methods are the members of a class that perform an action,and through writing methods you describe the behavior of data.

Accepted Answer

Methods in a class define the behavior of data. They perform specific actions and can manipulate instance variables within the class.

Question 6

The accessibility modifier identifies what type of value is returned when the method is completed.

Accepted Answer

The accessibility modifier determines the visibility of the method (who can access it) and has nothing to do with the return type of the method. The return type is specified separately in the method signature.

Question 7

The entries found inside the parentheses of the method heading are called the access modifiers.

Accepted Answer

The entries found inside the parentheses of the method heading are called parameters or arguments, not access modifiers. Access modifiers (like public, private) are used outside the parentheses to define the access level of the method.

Question 8

The body of a method can include statements that declare other methods.

Accepted Answer

The body of a method can include statements that perform operations, such as declaring variables or executing loops, but it cannot declare other methods. Methods must be declared within a class or an interface, not within another method.

Question 9

If a method does not return a value,the void keyword is placed inside the parentheses in the method heading.

Accepted Answer

The void keyword is used before the parentheses in the method heading to indicate that the method does not return a value.

Question 10

The Read( )method is different from the ReadLine( )method in that the Read( )returns an int and the ReadLine( )returns a string argument.

Accepted Answer

The Read() method in C# reads the next character from the input stream and returns it as an int, representing the character code. In contrast, the ReadLine() method reads a line of characters from the input stream and returns it as a string.

Question 11

A semicolon is placed on the end of a method heading following the parameter list.

Accepted Answer

A semicolon is placed at the end of a class heading, not a method heading, to indicate the end of the class declaration.

Question 12

Console applications require a Main( )method,unlike Windows applications that do not require a Main( )method.

Accepted Answer

Both console applications and Windows applications in .NET require a Main() method as the entry point for the application.

Question 13

One required entry for a method heading is the return type.

Accepted Answer

The return type is a required entry for a method heading.

Question 14

The definition of the method includes the entry inside the curly braces,which is sometimes called the body of the method.

Accepted Answer

The answer of The definition of the method includes the...

Question 15

In order to hold the screen when the program runs,programmers often add Console.Read( )as a last statement.

Accepted Answer

Console.Read( ) reads a single character from the console and allows the program to wait for user input before closing the window and ending the program. Therefore, adding this statement will hold the screen until the user presses a key.

Question 16

The Console class is defined in the System namespace.

Accepted Answer

The Console class is defined in the System namespace in C#.

Question 17

The following are examples of the access modifiers available in C#: public,personal,protected.

Accepted Answer

The access modifiers available in C# are public, private, and protected.

Question 18

In order to call a static method from another class,the class name must be used with the method name.

Accepted Answer

To call a static method from another class, the class name must be used with the method name as follows: ClassName.methodName().

Question 19

The Write( ),WriteLine( ),Read( ),and ReadLine( )methods are all overloaded.

Accepted Answer

The answer of The Write( ),WriteLine( ),Read( ),and ReadLine( )methods...

Question 20
