Exam 13: Program Development and Programming Languages

Fourth-generation languages are commonly used to access ____.

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

Case 13-1 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. -The Rainbow Trout Company uses the ____ approach,which emphasizes teams of people working closely together,which provides for continuous learning and adaptation as the project is developed.

Fourth-generation languages (4GLs)are ____.

Structured programming embodies a top-down design philosophy.

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

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

Ruby on Rails is a framework for developing dynamic Web applications that is written in the Ruby programming language

The basic selection control structure is the _________________________,in which the condition can only result in two possibilities-true or false (yes or no).

A structured program is divided into individual modules;each module represents a specific processing task.

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

____ are small programs that are designed to be inserted into Web

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.

____ is the first phase of the PDLC.

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.

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.

Comments are usually preceded by a specific symbol.

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.

It is easier to write comments- particularly comments explaining the logic of a program-at the time the program is coded,instead of trying to add those comments at the end of the project.

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