Holds addresses that refer to objects . You can assign any reference type (string, array, class, or interface) to an Object variable. An Object variable can also refer to data of any value type (numeric, Boolean , Char , Date , structure, or enumeration).15 Eyl 2021

To check the data type of a variable in R, use the typeof() function . The typeof() is a built-in R function that defines the (internal) type or storage mode of any R object.

An Object is an instance of a Class . When a class is defined, no memory is allocated but when it is instantiated (i.e. an object is created) memory is allocated. Defining Class and Declaring Objects. A class is defined in C++ using keyword class followed by the name of class.

For example, you can use the object type to specify the datatype of an attribute, column, variable, bind variable, record field, table element, formal parameter, or function result . At run time, instances of the object type are created; that is, objects of that type are instantiated.
