Data Types in Programming

Data Types

Integer

• A whole number, either positive, negative, or zero
• Examples: 1, -5, 0
• Can be used for counting, indexing, and performing arithmetic operations
• Typically stored as 32-bit or 64-bit signed integers

Float

• A number with a fractional part, can be positive, negative, or zero
• Examples: 3.14, -0.5, 0.0
• Used for decimal numbers, scientific notation, and very large/small numbers
• Typically stored as 32-bit or 64-bit floating-point numbers

String

• A sequence of characters, can be letters, digits, or special characters
• Examples: "hello", 'hello', "123"
• Used for text, labels, and descriptions
• Can be enclosed in single quotes or double quotes

Boolean

• A true or false value
• Examples: true, false
• Used for conditional statements, flags, and logical operations

Character

• A single character, can be a letter, digit, or special character
• Examples: 'a', '1', '+'
• Used for single characters, parsing text, and validation
• Can be enclosed in single quotes

Text Data

• Strings: Sequences of characters, can be letters, digits, or special characters, used for text, labels, and descriptions.
• Examples of strings: "hello", 'hello', "123"
• Can be enclosed in single quotes or double quotes

Logical Data

• Booleans: True or false values, used for conditional statements, flags, and logical operations.
• Examples of booleans: true, false

Single Characters

• Characters: Single characters, can be a letter, digit, or special character, used for single characters, parsing text, and validation.
• Examples of characters: 'a', '1', '+'
• Can be enclosed in single quotes
