C++ Arrays - Chapter 2 Flashcards

Vocabulary and key concepts covering C++ arrays, memory calculation, and string handling functions based on the Chapter 2 lecture notes.

Array

A collection of elements of the same type placed in contiguous memory locations, used to store a set of values under a single variable name.

Index Number

The position of an element in an array list (also referred to as a subscript) used to access that specific element.

Array Declaration Syntax

The statement syntax used to declare an array in C++: data_type array_name[size];

Array Memory Size Formula

The formula used to calculate total memory allocated for a single dimensional array: $\text{total\_bytes} = \text{sizeof(array\_type)} \times \text{size\_of\_array}$

Array Initialisation

Assigning initial values to array elements directly within their declaration statement (for example, int score[5] = {98, 87, 92, 79, 85};).

Null Character ('\0')

A character stored in a character array that serves as a string terminator.

cin >> (for String Input)

An input statement in C++ that reads characters until it encounters a white space, allowing only single-word strings to be stored.

Stream Input Functions for Strings

Functions such as getline() and get() that belong to stream classes and are used to input strings containing white spaces.

gets()

A console function used to input strings containing white spaces.

puts() and write()

Functions used to display string data in C++.
