Unstructured programs that do follow the rules of structured logic

Front 3

Structure

Back 3

A structure is a basic unit of programming logic; each structure is a sequence, selection, or loop

Front 4

Sequence Structure

Back 4

A Sequence structure contains a series of steps executed in order. A sequence can contain any number of tasks, but there is no option to branch off and skip any of the taks

Front 5

selection struction

Back 5

A selection structure or decision structure contains a questions, and, depending on the answer, takes one of two courses of action before continuing with the next task

Front 6

end structure statement

Back 6

An end-structure statement designates the end of a pseudocode structure

Front 7

what is another name for an "if-then-else" statement

Back 7

An if-then-else is another name for a selection structure

Front 8

Dual-alternative ifs

Back 8

Dual-alternative ifs (or dual-alternative selections) define one action to be taken when the tested condition is true and another action to be taken when it is false

Front 9

Single -alternatives ifs

Back 9

Single alternatives ifs (or single-alternative selections) take action on just one branch of the decision.

Front 10

null case

Back 10

The null case is the branch of a decision in which no action is taken

Front 11

loop structure

Back 11

A loop structure continues to repeat actions while a test condition remains true

Front 12

Repetition and iternation

Back 12

Repetition and iteration are alternate names for loop structure

Front 13

while...do

Back 13

In a while...do, or more simply a while loop, a process continues while some condition continues to be true

Front 14

Stacking Structures

Back 14

Stacking Structures is the act of attaching structures end to end

Front 15

Nesting Structure

Back 15

Nesting Structure is the act of placing a structure within another structure

Front 16

block

Back 16

A block is a group of statements that executes as a single unit

Front 17

priming input

Back 17

A priming input or priming read is the statement that reads the first input data record prior to starting a structured loop

Front 18

Goto-less Programming

Back 18

Goto-less programming is a name to describe structured programming, because structure programmers do not use a "go to" statement

Front 19

What are 3 basic structures

Back 19

- sequence

- selection

- loop
