Local
____________________ identifiers are not accessible outside of the function (block).
Reference
____________________ parameters are useful in three situations: • When the value of the actual parameter needs to be changed • When you want to return more than one value from a function • When passing the address would save memory space and time relative to copying a large amount of data
