    Data Types in C++ Programming

    • A data type is a set of values together with a set of operations.
    • C++ data types can be categorized into three main categories.

    Primary Data Types (Simple)

    Integer Data Type

    • Keyword: int
    • Requires 4 bytes of memory space
    • Range: -2147483648 to 2147483647
    • Examples: -6728, 0, 78, +763
    • Positive integers do not need a + sign
    • Commas are not used within an integer, but are used to separate items in a list

    Character Data Type

    • Keyword: char
    • Requires 1 byte of memory space
    • Range: -128 to 127 or 0 to 255
    • Used for characters: letters, digits, and special symbols
    • Each character is enclosed in single quotes
    • Examples: 'A', 'a', '0', '*', '+', '$', '&'
    • A blank space is a character and is written ' ', with a space left between the single quotes
    • Example declaration: char test = 'h'; char case = 'A';

    Boolean Data Type

    • Keyword: bool
    • Used for storing boolean or logical values
    • Can store either true or false
