(C++) data type

A type of data. As C++ is type safe, different types of data are distinguished. For example, the data type bool can only contain true and false, an integer only whole numbers and a double broken numbers.

There are standard data types (which are also keywords), 'extended data types' and user-defined data types, mostly classes.

The standard data types for C++ are as follows:

• bool
• char
• double
• float
• int
• long
• short
• void (in the form of void*)
• wchar_t

The range of each of these data types can be found with std::numeric_limits.

'Extended data types'

• Arrays
• class, e.g. std::string
• const
• pointer
• struct
