Data Types Flashcards
The operator used in a programming language that gives a value to a variable or constant.
Assignment Operator
A term in the study of logic and programming meaning a true or false value.
Boolean
A data type in programming that contains a symbol, letter, or digit, like ‘A’, ‘b’, ‘5’ or ‘#’.
Consists of 16 bits.
Character (Char)
A memory location in programming that is unchanged during the execution of the program once it has been given a value, unlike a variable which can be changed.
Constants
A classification identifying one of various types of data, such as real, integer or Boolean, that determines the possibles values for that type.
Data Type
A real number that has a whole part and a fractional part, like 3.14.
The general term for the base ten numbering system.
Decimal
Specifies properties of an identifier of a function, procedure, method, variable, constant, or class, but can also be used for other entities such as enumerations and type definitions.
Declaration
A data type in some languages that is designed to contain floating-point numbers, generally using twice as much memory as a float data type. In Java, this uses 64 bits of memory compared to a float that uses 32 bits.
Double
A data type in programming that contains a floating point value, more commonly referred to as a decimal value, like 1.5 or 3.14.
Float
A decimal value such as 1.5 or 3.14.
Floating Point
The process of assigning a beginning value to a variable or constant in a computer program.
Initialization
In object oriented programming, this is the process of bringing into existence an object defined by a class, in Java initiated by the term “new,” which calls a constructor appropriate for that object.
Instantiate
A data type in various languages which contains a positive or negative number value.
One bit is used to indicate positive or negative (sign bit).
Takes up 32 bits of memory.
Integer (int)
Names used in programming for classes methods, variables, and constants that help describe the general purpose and function associated with that item.
Meaningful Identifiers
A row of characters combined together to make a word, sentence, or other text-based value.
String
