Exam 8: Advanced Method Concepts

You name an argument in a method call using its parameter name and a ____ before the value.

The rules that determine which method version to call are known as ____________________.

When you don't know how many arguments you might eventually send to a method, you can declare a(n) ____.

If you assign a default value to any variable in a method's parameter list, then all parameters to the right of that parameter must have ____ values.

When you use a(n) ____ parameter, the argument used to call the method must have an assigned value.

You use the keyword ____ as a modifier to indicate an output parameter.

To ensure that the original value of an argument passed to a method remains unchanged after returning from the method, you should use a reference parameter or an output parameter.

When a method call could execute multiple overloaded method versions, C# determines which method to execute using a process called ____________________.

Omitted ____ arguments are ignored for betterness purposes on argument conversions.

What are two options for writing a called method that results in altering a single value in the calling method?

What is the difference between a reference parameter and an output parameter?

Describe the similarities and differences among method versions when the method is overloaded.

A(n) ____ parameter to a method is one for which a value is automatically supplied if you do not explicitly send one as an argument.

Given the following two method signatures, explain the reasoning behind how the C# compiler determines which method version to invoke for the call MyMethod(12) : private static void MyMethod( int a) private static void MyMethod( int a, char b = 'B')

Write the DisplayStrings() method called in the code below using a parameter array declared in the method header. The method should write its arguments in a single line, followed by a newline. What will the output be after running Main() ? using static  System.Console; class ParamsDemo { static void Main() { string[] names = {"Mark"), "Paulette"), "Carol"}; DisplayStrings("Ginger"); DisplayStrings("George"), "Maria"), "Thomas"); DisplayStrings(names); } }

____ involves the ability to write multiple versions of a method using the same method name.

Using a(n) ____ parameter is convenient when the variable to be passed does not have an assigned value at the time the method is called.

Overloaded methods sharing the same identifier must have the same return type.

Only one ____ keyword is permitted in a method declaration.

Suppose that you create overloaded method versions with the following declarations: private static void MyMethod( double d) private static void MyMethod( float f) Would MyMethod() run if it is called with an integer argument? Describe how C# determines which, if either, method should run when MyMethod() is called.
