Arrays
vWhen a variable is
indexed it is called an array
vArrays are used for
representing collections of data values, e.g. integers, strings, etc.
For example: dwarf(0) = “Sneezy”
dwarf(1) = “Dopey”
dwarf(2) = “Grumpy”
...
vElements of an array
must all be of the same type
vThe index of an
array element is also known as a subscript
Notice x0 and x1
are variable names, while x(0) and x(1) are different elements of array x
