C++ supports several built-in data types for storing different kinds of data. These include:
Integer types - used for storing whole numbers. Examples include int, long, short, and char.
Floating-point types - used for storing decimal numbers. Examples include float and double.
Boolean types - used for storing true or false values. The type is bool.
Character types - used for storing individual characters. Example is char.
Wide character types - used for storing characters from a wide character set. Example is wchar_t.
Pointer types - used for storing memory addresses.
Enumeration types - used for declaring a set of related named integer constants. Example is enum.
User-defined types - can be created by the user using classes, structs, and unions.
C++ also supports several other data types, such as arrays, functions, and references. It's also worth noting that C++ supports type casting, which allows you to convert a value of one data type to another.
