DATA TYPES, VARIABLES AND CONSTANTS

LEARNING OBJECTIVES  Be able to identify and explain the difference between data and information  Be able to identify, explain and apply constants and variables  Be able to identify and know how to apply different data types

WHAT IS DATA?  Data is facts and statistics collected together

WHAT IS INFORMATION?  Information is data, with a rule applied to it

THE DIFFERENCE  Data is the raw version of information. Data is information without any rules applied to it, to give context

VARIABLE  A variable is a programming concept that stores information, so it can be called upon later on in the program.  Dim ___ As ____?

DATA TYPES  Integer / (Number)  String / (Word)  Boolean / (True or False)  Double / (Number with Decimal)  Date / (A Date)  Character / (Letter)

WHAT DATA TYPES WOULD THESE BE?  Dim name As String  Dim moneyEarnt As Double  Dim gradeA_F As Character  Dim goalsScored As Integer  Dim canVote As Boolean
