What are the data types?
According to Wikipedia,
"In computer science and computer programming, a data
type or simply type is a classification identifying one
of various types of data, such as real-valued, integer or Boolean,
that determines the possible values for that type; the operations
that can be done on values of that type; the meaning of the data;
and the way values of that type can be stored."
"Almost all programming languages explicitly include the notion
of data type, though different languages may use different
terminology. Common data types may include:
- floating-point numbers,
- alphanumeric strings."
