Agile software development

In the program design step of the PDLC, the specifications developed during the problem analysis step are used to develop a(n) ____ for the program.

Algorithm

____ is a broad term to describe creating and managing an application throughout its entire lifecycle—from design through coding and testing, to maintenance, and, eventually, to retirement.

Application Lifecycle Management (ALM)

A(n) ____ is a software program that helps programmers develop software.

Application generator

____ was designed as an easy-to-learn beginner's language.

Programs created for mass distribution often have two stages of testing: an internal onsite test and one or more rounds of outside tests (called ____).

Beta tests

____ values are values that represent one of two states—yes (true) or no (false).

Boolean

The Rainbow Trout Company specializes in developing software that is useful to amateur and professional fishermen. They often work on projects with constantly changing requirements. To allow everyone, not just the original programmer, to understand the source code of a program, the Rainbow Trout Company follows a set of ____—a list of rules designed to standardize programming styles.

Coding standards

____ are notes within the actual program code that identify key features and steps of the program but that are written in such a way that the computer knows to ignore them when the program is executed.

Comments

A(n) ____ is designed for a specific programming language and translates programs written in that language into machine language so it can be executed.

Compiler

Fourth-generation languages are commonly used to access ____.

Databases

In a(n) ____ check, the programmer "walks" through the program design, keeping track of the values of any loop counters and other variables in a tracing table to ensure the program does what it is intended to do.

Desk

With the ____, the instructions in the loop are repeated as long as a certain condition is false.

Do until structure

____, which dates back to 1954, was designed by scientists and is oriented toward manipulating formulas for scientific, mathematical, and engineering problem solving applications.

FORTRAN

Although there is no precise definition of 3GLs, they are even further from machine language than fourth-generation languages, and, therefore, are much easier to use. _________________________

False

An IDE is a tool that prepares reports to be used with a software program quickly and easily.

False

An advantage to using 4GLs is that they can result in a smaller number of program statements and more efficient object code when they are compiled into machine language.

False

C is an object-oriented programming language developed by Sun Microsystems. _________________________

False

One or more rounds of outside tests for programs created for mass distribution are referred to as alpha tests. _________________________

False

Structure charts are used to illustrate the step-by-step logic that is to take place within a program, module, or method.

False

The figure above shows the selection control structure. _________________________

False

The repetition control structure is also called the selection control structure.

False

With a(n) sequence control structure, the direction that the program control takes depends on the results of a certain condition. _____________________________

False

With most programs, compiling or interpreting a program will result in errors—the assembling process consists of locating and correcting these errors.

False

With the do until structure, the instructions in the loop are repeated as long as a certain condition is true. _________________________

False

Program ____ use graphic symbols and relational operators (such as < for "less than" and = for "equal to") to portray the sequence of steps needed to fulfill the logic in that program, module, or method.

Flowcharts

____ create the forms or screens used to input data into a program or database.

Form generators

Rather than creating a complete object module for a program, a(n) ____ reads, translates, and executes the source program one line at a time.

Interpreter

Kelly is a college sophomore majoring in computer science. She is interested in gaining exposure to the most useful and current programming languages and techniques. One of the languages that Kelley is learning is ____ an object-oriented programming language that is commonly used to write Web applications.

Java

____ are small programs that are designed to be inserted into Web pages and run using a Java-enabled Web browser.

Java applets

____ errors occur when a formula is written incorrectly, when a mistake is made with a decision condition, or when the wrong variable name is used.

Logic

Programmers often use temporary dummy print statements—print statements that are temporarily inserted into the code—to help locate a ____.

Logic error

The earliest programming languages—machine language and assembly language—are referred to as ____.

Low-level languages

The first official recorded use of the word "bug" in the context of computing is associated with the temporary failure of the ____ computer.

Mark II

Two of the most significant approaches to programming are procedural programming and ____.

Object-oriented programming

____ was created to fill the need for a teaching tool to encourage structured programming.

Pascal

____ is the first phase of the PDLC.

Problem analysis

Kelly is a college sophomore majoring in computer science. She is interested in gaining exposure to the most useful and current programming languages and techniques. During the summer, Kelly will be writing a compiler as part of a research project. To prepare, she is learning ____, a functional language.

Scheme

A ____ is simply a series of statements that follow one another. After the first statement has been carried out completely, the program control moves to the next statement, and so forth.

Sequence control structure

A(n) ____ occurs when the programmer has not followed the proper rules of the programming language being used.

Syntax error

A program bug is an error that causes a program to malfunction.

True

A(n) macro is a sequence of saved actions (such as keystrokes, mouse clicks, and menu selections) that can be replayed whenever needed within the application program in which it was created. _________________________

True

If an application is going to need to interact with existing programs, it will likely be coded in the same language as those other programs.

True

In a(n) procedural program, variables can be accessed and their values changed from any module in the program, as appropriate. _________________________

True

In addition to its traditional uses, COBOL is evolving to support new applications.

True

Java source code cannot be converted into object code using a Python compiler. _________________________

True

Much of the coding in a declarative programming language consists of mouse clicks to select instructions and issue commands to the program. _________________________

True

Procedural programming utilizes procedures, which are also called modules or subprograms. _________________________

True

Program coding is the process of writing the actual program steps in the proper format for a particular programming language. _________________________

True

Pseudocode expresses the steps in a program, module, or method, but uses English-like statements in place of the flowchart's graphical symbols.

True

Python programs run on computers using the Windows, Linux, UNIX, Mac OS X, or OS/2 operating systems, as well as on some mobile devices.

True

Run time errors are noticed after all syntax errors are corrected and the program can be executed. _________________________

True

To use a macro recorder, you start the macro recorder and then you perform the desired tasks—the macro recorder records all of the keystrokes and mouse clicks you make until the recorder is turned off.

True

User documentation normally consists of a user's manual containing instructions for running the program, a description of software commands, and so forth. _________________________

True

With a logic error, the program will run but the output will be wrong.

True

In a computer program, ____ are named memory locations that are defined for that particular program and are used to store the current value of data items used in the program.

Variables

Fourth-generation languages (4GLs) are ____.

very-high-level languages
