Edexcel GCSE Computer Science (1CP2) Exam Questions

• A Executes the line (1)
• The only correct answer is A. The correct answer is that the interpreter executes the line.
• B is not correct because an interpreter does not produce object code; that is what a compiler does
• C is not correct because an interpreter does not save the translated code to a file
• D is not correct because the interpreter executes the current line before it translates the next line

Award one mark for:

• The whole program (before it is run) (1)

Allow all of the code/the entire program/the whole program in one go

Do not accept one line/statement at a time or each line as it is executed

Do not accept translating only the lines that contain errors

Award up to two marks for a linked description such as:

• The compiler reports all syntax errors after translation has finished (1) whereas the interpreter stops at the first error it finds (1)
• The interpreter reports a syntax error as soon as it finds one (1) and does not translate/execute any more of the program (1)
• The compiler continues translating after an error (1) and reports the errors at the end (1)
• The interpreter stops translating when it reaches an error (1) but the compiler finishes translating before reporting errors (1)

Do not accept answers about fixing/correcting errors or about object code.

Do not award 'the compiler finds more errors' without saying errors are reported at the end.
