Comments

What is the definition, how can we call some datatype as primitive some as non-primitive.

Primitive data-type is a basic type is a data-type provided by a programming language as a basic building block
A variable of a non-primitive type doesn't contain the value directly; instead, it is a reference (similar to a pointer)

cool, that makes it a complete answer. Thanks for supporting people and helping them.

thanks, always happy to help :)

Answer 2

A primitive data type is either a data type that is built into a programming language, or one that could be characterized as a basic structure for building more sophisticated data types.
Examples of primitive data types include integers, floating point numbers and individual characters in text. Each of these primitive data types is an example of something that doesn’t require a large amount of data for representation.
1.Characters simply correspond to a single reference point in an ASCII chart.
2.Integers are numbers that do not need complex identifiers such as exponents and decimal points.
3. Boolean values require only a binary choice between two possible values.
and the classic primitive data types : (Wikipedia)
1.Character (character, char);
2.Integer (integer, int, short, long, byte) with a variety of precisions;
3.Floating-point number (float, double, real, double precision);
4.Fixed-point number (fixed) with a variety of precisions and a programmer-selected scale.
5.Boolean, logical values true and false.
