Solution

Primitive data types are the most basic data types available within a programming language. They are the building blocks of data manipulation and contain pure, simple values of a kind. Examples of primitive data types include:

  1. Integer: This is used to store numeric values without decimal points. For example, 10, 20, 30 are integers.

  2. Float: This is used to store numeric values with decimal points. For example, 10.5, 20.6, 30.7 are floats.

  3. Boolean: This is used to store true or false values.

  4. Char: This is used to store a single character. For example, 'a', 'b', 'c' are characters.

Composite data types, also known as non-primitive data types, are more complex data types that are built from primitive data types. They can be used to store multiple values and complex data. Examples of composite data types include:

  1. Array: This is used to store multiple values of the same type. For example, an array of integers can store multiple integer values like [10, 20, 30].

  2. String: This is used to store a sequence of characters. For example, "Hello, World!" is a string.

  3. Object: This is used to store a collection of properties, where each property is a primitive or composite data type. For example, a person object can have properties like name (string), age (integer), and hobbies (array).

  4. List: This is similar to an array but can store multiple values of different types. For example, a list can store [10, "Hello", true].

In summary, primitive data types are simple and hold a single value, while composite data types are complex and can hold multiple values or properties.
