5.2 Language Translators Cambridge iAS 9618

What is the role of an assembler?

• It translates assembly language into machine code

• It converts high-level languages to assembly code

• It executes machine code directly

• It only translates Java programs

Why is a compiler needed for high-level programming languages?

• It translates the entire program into machine code before execution

• It translates one line at a time during execution

• It runs programs without translating them

• It is only used for debugging

How does an interpreter work?

• It translates and executes code line by line

• It compiles the entire code before execution

• It converts machine code to high-level language

• It only works for assembly language

Which of the following is an advantage of using a compiler?

• Compiled programs run faster than interpreted ones

• It provides real-time execution feedback

• It does not require a separate compilation step

• It allows partial execution of code

What is a drawback of using an interpreter?

• It can be slower since it translates code during execution

• It does not detect syntax errors

• It does not support high-level languages

• It only works on Windows

Which situation is best suited for using an interpreter?

• Debugging and testing small parts of a program

• Running final versions of software for performance

• Converting binary code into human-readable form

• Optimizing compiled code for efficiency

How does Java use both compilation and interpretation?

• Java code is compiled into bytecode, which is interpreted by the Java Virtual Machine (JVM)

• Java does not use compilation at all

• Java directly translates to machine code

• Java programs cannot run on multiple operating systems

What does an Integrated Development Environment (IDE) provide for coding?

• Context-sensitive prompts to assist with coding

• Automatic compilation without errors

• Direct hardware control

• Only works with compiled languages

How does an IDE help with initial error detection?

• It performs dynamic syntax checks while coding

• It only detects errors after execution

• It automatically fixes errors without user input

• It ignores logical errors in code

What is the function of prettyprint in an IDE?

• It formats code for better readability

• It executes code line by line

• It converts code into machine language

• It removes unnecessary comments
