CTA chapter 13

Software development

Another name for programming.

Pseudocode

An outline of the logic of the program to be written.

Selection

Logic structure, also known as IF-THEN-ELSE, that controls program flow based on a decision.

high level

Programming languages that are closer to the language of humans.

Debugging

The process of testing and then eliminating program errors.

Documentation

Program step that involves creating descriptions and procedures about a program and how to use it.

Machine

The first-generation language consisting of 1s and 0s.

Interpreter

Converts a procedural language one statement at a time into machine code just before it is to be executed.

5GL

Generation of computer languages that allows a person to provide a system with a problem and some constraints, and then request a solution.

Natural Langauge

5GL that allows more direct human communication with a program.

Sequential

The programming logic structure in which one program statement follows another.

Object code

A compiler converts the programmer’s procedural language program, called the source code, into a machine language code, called the _________.

Query

These 4GL languages enable nonprogrammers to use certain easily understood commands to search and generate reports from a database.

Program maintenance

This step in the six-step programming procedure is the final step.

Data

What a program processes.

Modules

The major processing steps identified in a top-down program design.

Object-oriented

Unlike traditional systems development, this software development approach focuses less on the procedures and more on defining the relationships between previously defined procedures.

high-level language

Natural languages are considered to be a(n) _________.

Structured programs

One of the best ways to code effective programs is to use the three basic logic structures to create _________.

Program test

This step in the six-step programming procedure involves desk checking and searching for syntax and logic errors.
