Exam 3: Understanding Structure

Why is it best to use only three programming structures?

Structured programming is sometimes called goto-less programming.

Describe how you can straighten out an unstructured flowchart segment.

Structured programs use spaghetti code logic.

Attaching structures end to end is called ____ structures.

Describe a loop structure.

A structured program must contain a sequence, selection, and loop structure.

Fill in the blank in the following pseudocode: if someCondition is true then    do oneProcess ____    do theOtherProcess Endif

Because you may stack and nest structures while retaining the overall structure, it might be difficult to determine whether a flowchart as a whole is structured.

With a(n) ____, you perform an action or task, and then you perform the next action, in order.

In older languages, you could leave a selection or loop before it was complete by using a ____ statement.

The maximum number of entry points that any programming structure can have is ____.

All logic problems can be solved using only these three structures: sequence, selection, and loop. The three structures, of course, can be combined in an infinite number of ways. What are two general ways structures can be combined?

No matter how complicated it is, any set of steps can always be reduced to combinations of the two basic structures of sequence and loop.

The following pseudocode is an example of ____.

The action or actions that occur within a loop are known as a(n) ____.

One way to straighten out an unstructured flowchart segment is to use the ____ method.

The case structure is a variation of the ____ structure.

Programs that use _____ code logic are unstructured programs that do not follow the rules of structured logic.

Pseudocode uses the end-structure statement ____ to clearly show where the structure ends.
