Exam 2: First You Need to Plan the Party Problem-Solving Process

You should test an algorithm with invalid data because users sometimes make mistakes when entering data.

The parallelogram symbol in a flowchart is called a(n) ____ symbol.

Most algorithms begin with an instruction that enters the input items into the computer.

The first step that programmers follow when they solve problems is to plan the algorithm.

When analyzing a problem, you always search first for the input, and then for the output.

Before you begin the desk-check, you first choose a set of sample data for the input values, which you then use to manually compute the expected output values.

If you are having trouble analyzing a problem, try reading the problem specification several times, as it is easy to miss information during the first reading.

Most algorithms end with an instruction to print, display, or store the output items.

When planning an algorithm, you need to create both a flowchart and pseudocode.

Besides using pseudocode, programmers also use ____ when planning algorithms.

Display, print, and store refer to a file on disk, the printer, and the computer screen, respectively.

A helpful way to identify the ____ is to search the problem specification for what information the computer will need to know to print, display, or store the output items.

To avoid confusion, it is important that the algorithm is consistent when referring to the input and output items.

Programmers use the pseudocode as a guide when coding the algorithm, which is the ____ step in the problem-solving process.

Not all algorithms require a processing item.

The oval symbol in a flowchart is called the ____ symbol.

You can only perform a desk-check using an algorithm's pseudocode.

The rectangle in a flowchart is called the ____ symbol and is used to represent tasks such as calculations.

The ____ step is the most difficult of the problem-solving steps, and it requires a lot of time, patience, and effort.

You ____ an algorithm to verify that it is not missing any steps, and that the existing steps are correct and in the proper order.
