Q

Loop Control Variable

A

A variable that determines weather a loop will continue

2
Q

Definite Loop

A

Which the number of repetitions is predetermined value.

3
Q

Counted or Counter-Contolled Loop

A

A loop whose repetitions are managed by a counter.

4
Q

Increment

A

A variable is to add a constant value to it, frequently 1.

5
Q

Decrement

A

A variable is to decrease it by a constant value, frequently 1.

6
Q

Counter

A

One for which you cannot predetermine the number of executions.

8

Occur when a loop structure exist within another loop structure.

9

Outer Loop

A

This loop contains another loop when nested.

14
Q

Pretest Loop

Tests a loop control variable after each iteration, meaning that the loop body executes once.

16
Q

Accumulator

A

A variable that you use to gather or accumulate values.

17
Q

Summary Report

A

List only totals, without individual detail records.

18
Q

Defensive Programming

A

A technique with which you try to prepare for all possible error before they occur.

19
Q

Validate Data

A

Ensuring data items are meaningful and useful. Examples include ensuring that the values are correct data type or that they fall within an acceptable range.

20
Q

GIGO

A

(Garbage in, Garbage Out) means that if your input is incorrect, you output is worthless.

21
Q

Forcing

A
