Data Structure
From CS253: Data Structures and Algorithms. Lecture 2: Basics
Primitive Data Types
- Integer Types
- Purpose: Store whole numbers (positive, negative, or zero).
- Examples:
int (e.g., in Python, Java, C++).short, long (e.g., in Java and C++).
- Range depends on size (e.g., 4 bytes in Java: −2^31 to 2^31−1).
- Floating-Point Types
- Purpose: Store numbers with fractional parts.
- Examples:
float, double (e.g., in Python, Java, C++).
- Used for scientific calculations and when precision is important.
- Character Type
- Purpose: Store a single character.
- Examples:
char (e.g., in Java, C++).- Unicode support allows representation of a wide range of characters
(e.g., ASCII, UTF-16).
- Boolean Type
- Purpose: Store
true or false values.
- Examples:
bool (e.g., in Python, C++).
