| Description |
|
Keyword used to indicate the value to return from a function. The value being returned must be the same datatype as defined in the function declaration. Functions declared with void can't return values and shouldn't include a return value. The keyword return may also be used to break out of a function thus not allowing the program to read the remaining statements (see the third example above). |
