C++ variable

In C++, variables are used to store and manipulate data. Each variable has a specific data type, such as integer, float, or character, that determines the type of data it can store. When you declare a variable in C++, you must specify its data type and give it a name. Once a variable is declared, you can assign a value to it using the assignment operator (=), and you can perform operations on it using operators like +, -, *, and /. Understanding variables and data types is essential for learning to write programs in C++.
