Data types03
There are three main data types in C++: primitive, derived, and user-defined. Primitive types include basic types like int and float. Derived types include arrays, which can contain collections of other data types. User-defined types encompass structures and enums, which are custom data types created by the programmer. Common primitive data types vary in size and range depending on the type.

- 1. DATA TYPES • Primitivedata types – int, float, double, char • Derived data types – Arrays come under this category – Arrays can contain collection of int or float or char or double data • User defined data types – Structures and enum fall under this category.
