Chapter 4 - Variables
Variables are used in a program so that values can be represented with meaningful names. For example, when a variable named "Length" is used in a program, it is clear that its value is distance. The use of variables is good programming style because code is easier to modify and easier for a programmer to understand. A variable is a named memory location that stores a value. A variable must be declared before it is used.

Chapter 5 - Decision Structures
Decision Structures like "if ...then" statements control the flow of a program and provide parameters in which results are displayed.
1. Decision structures in programming are all about how the sequence of execution of program statements.
2. Inside the blocks of event code, the next level of statements that you can use to control the sequence of statements includes the traditional decision statements likeIf-Then-Else and Select Case.

Algorithm: A set of steps that tell how to solve a problem.
Boolean expression: An expression that evaluates to either True or False.
Counter: A variable used to store a value that is updated by a constant value.
Decision structure: A statement that uses a condition to determine which set of statements to execute.
Lifetime: The duration in which a declared variable exists in memory.
Logical operators: Operators (And, Or, and Not) that may be used to form a Boolean expression.
