1. 1D Array

   • Series of values
   • Dim array() as integer = {3,4,5,6,7}
   • Dim array(4) as integer
     • array(0) = 1
   • Uses less memory than making individual variables

2. 2D Array

   • Dim array(3,4) as integer
   • Stores values in a grid
   • Column then row
   • array(2,3) = 4

3. 1D array in parallel

   • Define 2 arrays and counting variable then
     • Console.writeline( Array1(i) & Array2(i))
       • i +=1

4. Check for item in array

   • For i = 0 to length.array - 1
     • if array(i) = Wanted_line
       • Print(Wanted_line)
         • Next
