C++ Data Types and Structures

These flashcards cover key vocabulary and concepts related to C++ data types and structures, including definitions of types, operators, and functions.

char

A C++ simple data type that is always 1 byte in size.

bool

A data type in C++ that contains only two values: true and false.

enum

A user-defined type in C++ that consists of a set of named integral constants.

struct

A composite data type in C++ that is used to bundle related variables.

union

A C++ struct that allows storing different data types in the same memory location.

sizeof

A C++ unary operator that returns the size in bytes of its operand.

floating point type

A data type that represents numbers with fractional parts using decimals.

integral type

A data type that represents whole numbers without fractions.

combined assignment operator

An operator that combines assignment and another operation, e.g., +=, -=.

aggregate operation

An operation that applies to the entire data structure instead of individual components.

ASCII

A character encoding standard that represents characters as one-byte integers.

header file

A file containing declarations and definitions that can be included in other C++ files.

typedef

A keyword in C++ used to create an alias for existing data types.

pointer

A variable that holds the memory address of another variable.

reference

An alias for another variable that allows direct access to its value.

human-readable type

A data type that is easily understood and interpreted by programmers.

scientific notation

A way of representing numbers that are too large or small to be conveniently written in decimal form.

data type

A classification that specifies which type of value a variable can hold.

machine-dependent

Size or behavior that can vary based on the machine architecture.

structured data type

A data type that is a collection of different data types bundled together.
