C++ supports three kinds of object types:Fundamental types are built into the language (such as int, float, or double). Instances of these fundamental types are often called "variables." Derived types are new types derived from built-in types. Class types are new types created by combining ...

Data types in C can be divided into 2 main categories-basic data types and derived. BasicC programming languagedata types are built-in datatypes that store fundamental information such as numbers, letters, and text. Some of the commonly used basic data types in C are char (character), int ...
