C++ is a powerful, general-purpose programming language known for its performance and versatility. It's widely used in game development, system programming, and high-performance computing. Understanding its basic syntax is crucial for any aspiring C++ programmer.
Essential Elements
1. Variables
-
Declaration: Variables must be declared before use. This involves specifying the variable's name and data type.
int age; // Declaring an integer variable named "age" float height; // Declaring a floating-point variable named "height" -
Data Types: C++ supports various data types to store different kinds of information:
int: Whole numbers (e.g., 10, -5)float: Decimal numbers (e.g., 3.14, -2.5)double: Double-precision floating-point numbers (for greater precision)char: Single characters (e.g., 'A', '!', '
