- - - - Iteration
        
        Iteration is when the program loops through a section of it's code until a requirement is met.
      - Selection
        
        Selection is when the program must make a decision and choose a path to follow based upon the information it's given
      - Sequence
        
        Sequencing is when the program operates in a linear fashion where each line of code is executed and then the next.
  - - - Variables are like named addresses in memory that are used to store data that is important for the program to function. Each variable must also contain a data type which determines what kind of value the variable will hold.
        
        Boolean
        
        This type of variable stores a TRUE or FALSE state
        
        Float
        
        This type of variable stores numerical values that can also be in the form of decimals and can be operated on mathematically
        
        String
        
        This type of variable stores a set of letters or words and isn't able to be used in mathematical operations
        
        Integer
        
        This type of variable stores whole numerical values and can be operated on mathematically, to an extent
        
        Character
        
        This type of variable stores a single alphanumerical character
      - Arrays are used as sort of a collection of variables of similar, related data
    - - Arithmetic operators allow the programmer to define what kind of calculations they wish for the computer to perform in a program.
        
        +
        
        Addition
        
        -
        
        Subtraction
        
        *
        
        Multiplication
        
        /
        
        Normal division
        
        DIV
        
        Integer division - Only returns the integer in a division and not the decimal place or remainder
        
        MOD
        
        Modulo - Finds and returns the remainder of a division of two positive numbers
      - Relational operators allow the programmer to make assignments and comparisons to variables at any point in the code, they are usually used in selections and iterations.
        
        =
        
        Assignment
        
        ==
        
        Equivalence
        
        < and >
        
        Greater Than and Less Than
        
        <=
        
        Greater Than or Equal to
        
        =>
        
        Less Than or Equal to
        
        !=
        
        Not Equal to
      - Boolean operators allow the programmer to combine relational operators to give more complex decisions
        
        OR
        
        Condition is met when EITHER of the relational operators are set to TRUE
        
        AND
        
        Condition is met when BOTH relational operators are set to TRUE
