the whole program from the point of declaration

only the subroutine in which it is declared

every subroutine that is called from within the program at run time

only the main program block and any nested loops

a copy of the value is passed, so the original outside the subroutine is unchanged

the parameter cannot be changed at all once set

the address of the variable is passed, so changes affect the original

the parameter is always treated as a fixed constant

a subclass inheriting attributes from a superclass

the same method name behaving differently depending on the object's class

translating high-level source code into machine code

bundling data and methods together and keeping the data private

the same method name to behave differently depending on the object's class

two separate classes to share the identical set of attributes and inherited methods between them

a high-level program to run directly without any translator at all

data and the methods acting on it to be stored privately

It translates and executes the source one statement at a time

It translates the whole source program into machine code before execution

It cannot detect or report any syntax errors during the translation stage

It is always slower at run time than an interpreter executing the same code

The stream of tokens is checked against the grammar rules of the language to build a parse tree

Final machine code is generated and optimised

The source is broken into tokens and identifiers are recorded in the symbol table

The code is optimised for speed

syntax error

runtime error

translation error

logic error
