C++ Variable Types


In C++, a variable is a named memory location that holds a value of a particular type. 

The type of a variable determines the amount of memory that is allocated for the variable, as well as the operations that can be performed on the variable.

Here's an example of declaring and initializing a variable in C++
int x = 10; // declare and initialize an integer variable

In this example, the variable x is declared as an integer using the int keyword.

 The = operator is used to assign an initial value of 10 to the variable.

C++ has several built-in data types for variables, including:

int: an integer type that can hold whole numbers, such as 1, 2, 3, etc.double:

 A floating-point type that can hold decimal numbers, such as 1.0, 2.5, 3.14159, etc.bool: 

A Boolean type that can hold true or false.char: a character type that can hold a single character, such as 'a', 'b', 'c', etc.

In addition to these built-in types, C++ also allows you to create your own custom data types using classes and structures.
