5.2 Translators and IDE's

What is the primary purpose of a translator in programming?

• To speed up hardware
• To convert low-level code into high-level code
• To convert human-readable code into machine-readable code
• To compile web pages

Which translator reads and executes a program line-by-line?

• Compiler
• Assembler
• Loader
• Interpreter

What happens if an error is found while using an interpreter?

• The code is skipped
• The interpreter stops execution
• The program is compiled anyway
• The error is ignored

What is produced by a compiler if the source code has no errors?

• Bytecode
• Source code
• Object code
• Interpreter

What happens when a compiler finds errors in the source code?

• Only correct lines are executed
• An error list is generated and no object code is produced
• The program is interpreted instead
• The compiler automatically fixes the errors

What is a key disadvantage of using an interpreter for the user?

• Requires only the object code
• Needs both source code and interpreter every time
• Translates once and runs multiple times
• Faster execution than a compiler

Why is a compiler preferred when the program is finished and stable?

• It makes debugging easier
• It finds partial errors only
• It helps create an executable file
• It skips syntax checking

What is bytecode?

• Source code
• Assembly code
• Platform-specific machine code
• Intermediate code interpreted by a virtual machine

Which programming language uses bytecode and a virtual machine?

• C++
• Java
• HTML
• SQL

What is a major advantage of compiled programs for users?

• They can edit the source code
• They need the interpreter to run the program
• They run faster and don’t need source code
• They detect errors while running
