Function Declaration, contd.

• • the return command, returns a value when the function is called
  • • if there is nothing to return (void), then no return command is needed
    • the return variable type must match the type in the declaration
    • if you call return, then the function exits; any code after a return in a function will be ignored
  • variables declared inside of a function cannot be seen outside of this function
  • • this means you can reuse variable names within other functions
