🔣 C++ Variables

Variables in C++ are containers for storing data values. Every variable has a data type that defines the kind of value it can hold, like int, float, char, or string.

💡 Tip: Always initialize variables before using them in C++, especially with int or float, to avoid garbage values.

🔧 Common C++ Data Types

int — Integer numbers (e.g. 5, -23, 0)
float — Decimal numbers (e.g. 3.14, -0.5)
char — Single characters (e.g. 'A', 'z')
string — Text strings (e.g. "Hello")
bool — Boolean values (true or false)
