Data and Data Types

•A data type is a specific set of data values, along with a set of operations on those values.

•Data is stored in the computer’s memory.

•Data is like post office boxes, some are larger than others.

•Two data types for now:

–The char Data Type – describes data consisting of one alphanumeric character. We enclose them in single quotation marks, e.g., ‘A’ ‘a’ ‘_’ ‘8’

–The string Data Type – describes data consisting of a sequence of characters. We enclose them in double quotation marks, e.g., “Hello” “My name is Rhonda”
