array

a named storage location in memory, which can hold a group of values.

size declarator

the number inside array’s brackets

elements

storage locations in an array

subscript

a unique number to which each element in array is assigned

initialization list

the series of values separated with commas

bounds checking

when programming language do not allow a program to use an invalid array subscript. Typically happens during runtime

off-by-one error

error which occurs when a loop iterates one time too many or one time too few

For Each loop

a specialized version of the “For” loop that is known for simplifying array processing when your task is to step through an array, retrieving the value of each element

search algorithms

is a techniques that have been developed to locate specific item in a larger collection of data, such as an array

sequential search algorithm

an algorithm that uses a loop to sequentially step through an array, starting with the first element. It compares each element with the value being searched for and stops when the value is found or the end of the array is encountered.

total

accumulator variable in the algorithm

index

loop counter variable in the algorithm

get the total of the values

the first step in calculating the average of the values in an array is to…

subscript

by using ______, it is possible to establish relationship between data stored in two or more arrays

parallel arrays

are two or more arrays that hold related data, and the related elements in each array are accessed with a common subscript

one dimensional arrays

an arrays that can hold only one set of data

two-dimensional arrays, 2D arrays

an arrays that can hold multiple sets of data

element

this is an individual storage location on an array
