Exam 6: Modularizing Your Code With Methods

The benefit of using methods is known as ____________ because you are writing code to perform a task once and then reusing it each time you need to perform the task.

____________ are useful for establishing two-way communication between methods.

A method definition has two parts: a header and a body.

Dividing a large problem into several smaller problems that are easily solved is sometimes called ____________.

void methods are useful for simplifying complex conditions that are tested in decision and repetition structures.

Nested if statements can be useful for modularizing input validation.

Methods usually belong to a class, so you must write a method's definition inside the class to which it is supposed to belong.

When an argument is ____________, only a copy of the argument's value is passed into the parameter variable.

The method header is always terminated with a semicolon.

In C#, you declare a reference parameter by writing the ____________ keyword before the parameter variable's data type.

The ____________, which appears at the beginning of a method definition, lists several important things about the method, including the method's name.

A method that has an output parameter must set the output parameter to some value before it finishes executing.

When a ____________ finishes, it returns a value to the statement that called it.

The value that is returned from a method can be used like any other value.

When you call a method that has a reference parameter, you must also write the keyword ref before the argument.

The statements that make up the method body are enclosed inside a set of curly braces.

When working with value-returning methods, the data type of the value that the method returns is commonly called the method's ____________.

In C#, you declare an output parameter by writing the ____________ keyword before the parameter variable's data type.

A value-returning statement must have a(n) ____________ statement.

You have to write the data type for each parameter variable that is declared in a parameter list.
