The following table describes the pass modes for function
arguments.
Pass mode
in : The default. Specifies an input argument, used when
you only want to get the argument's value. Any changes made
to this argument are not reflected outside of the function.
out : Specifies an output argument, used when you only
want to set the argument's value. This argument is modified
in a function and the new value is passed back out of the
function when the function ends.
inout : Specifies an input and output argument, used when
you want to get the argument's current value and you want
the function to change that value and pass the new value
out.
