12Computers can do many different jobs because they are [blank_start]programmable[blank_end].
- Aprogrammable
13A [blank_start]function[blank_end] is a portion of code within a larger program that performs a specific task; it returns a [blank_start]single value[blank_end].
- Afunction
- Bsingle value
14A [blank_start]bubble sort[blank_end] is an algorithm that compares adjacent items and swaps those that are out of order.
- Abubble sort
15In creating a model of the program, programmers frequently use the following two design tools: [blank_start]pseudocode[blank_end] and [blank_start]flowcharts.[blank_end]
- Apseudocode
- Bflowcharts
16[blank_start]Pseudocode[blank_end] is a cross between human language and a programming language.
- APseudocode
17A [blank_start]flow chart[blank_end] is a graphical representation of the logical steps to carry out a task; it shows how steps relate to each other.
- Aflow chart
18A [blank_start]runtime error[blank_end] is an error that occur while the program is running. These are usually [blank_start]logical[blank_end] errors, such as mathematical errors.
- Aruntime error
- Blogical
19In Visual Logic, the [blank_start]assignment[blank_end] statement is represented by a rectangle.
- Aassignment
20In VL, input and output statements are represented by a [blank_start]parallelograms[blank_end].
- Aparallelogram
21In programming, [blank_start]variables[blank_end] are used by the program as storage locations for data.
- Avariables
22[blank_start]Numerical[blank_end] data is entered as digits (sometimes with one decimal).
- ANumerical
23The name of a variable should [blank_start]describe[blank_end] the type of data being held by the variable.
- Adescribe
