6. Arrays
Single Dimensional
syntax & style
size
index range
how stored in memory
data types
referencing single elements of the array
initializing syntax & rules
Parallel
Concerns
running off end
comparing
assigning one array to another
outputting content

7. Arrays
What kind of loop to use
‘for’ loop used when know how many elements to store or process
usually ‘while’ is used if do not know
loop should count the number of stored elements

8. Arrays
Two-dimensional Arrays
syntax & style
how stored in memory
C – Strings
what it is (2-D array of char)
how used to store strings
referencing a single string in an array of C-strings

9. Functions
