Introduction to Problem Solving: Arrays

These flashcards cover key concepts and vocabulary related to arrays in problem-solving, including their definitions and functions in programming.

Array

A data structure that stores a collection of homogeneous data items, organized by a single variable name.

Element

An individual item within an array, accessed by its index.

Index

A position number used to access an element in an array, typically starting from 0.

Subscript

A notation used to distinguish elements in an array, often enclosed in parentheses following the array name.

Accumulator

A variable that collects a total or sum as a series of values are added.

Direct Access

A method to retrieve an array element immediately using its index.

Sequential Access

Accessing array elements one by one, starting from the first position.

Linear Search

An algorithm that checks each element in an array sequentially to find a specific value.

Modular Programming

A programming practice that divides a program into separate, manageable modules.

Mean

The average value of a set of numbers, calculated by dividing the sum of the values by their count.

Algorithm

A step-by-step procedure for solving a problem or accomplishing a task.

Homogeneous Data

Data items that are of the same type and length.

Pseudocode

A simplified programming structure that uses plain language to outline algorithms.

DO Loop

A control flow statement used to repeat a block of code a specified number of times.
