What is an Array?

• What if we wanted to hold a large number of values?

• • would require a large number of variables
  • would make the program really messy to work with
  • would cease to be “human readable” code

• One answer is to use an array

• • array: an indexed list of variables of the same type
  • we can set the number of elements in the array
  • each array is only one variable, but contains how ever many variables we need
  • thus, code is much easier to read and work with when we only need to deal with single items that represent a larger amount of variables
