J277 2.5 Programming languages and IDEs consolidation

Part 4 of 4 · J277 2.5 · Programming languages and IDEs

The consolidation worksheet for OCR J277 2.5, applied to a studio developing and releasing a Python game.

Students will:

  • choose the language level a stated need calls for
  • select a translator and justify it against the studio's needs
  • read evidence from a development session and name the facility
  • structure an answer as point, mechanism and link
  • avoid generic lists in place of applied explanation

Inside: 3 explanation cells, 1 multiple-choice question, 1 fill-in-the-blanks cell and 6 written answers. 38 marks, about 60 minutes.

Programming languages and IDEs consolidation

An independent studio is developing a puzzle game in Python. Programmers write and test the game in an IDE, then prepare a version for players to install.

Use the retrieval tasks to identify gaps before completing the applied questions independently.

Use this answer structure for scenario questions:

  1. Point: name the language characteristic, translator or IDE facility.
  2. How it works: explain precisely what it does.
  3. Link: connect that explanation to a stated need of the studio or its players.

The link prevents answers becoming generic lists of remembered facts.

Fill in the blanks6 marks
Complete the retrieval summary. Python is a label 1 language. The CPU executes label 2 code. A label 3 translates a whole program and can produce an executable. An label 4 translates and executes one statement at a time. An IDE's label 5 changes source code, while its label 6 executes the program.
  • high-level
  • low-level
  • machine
  • compiler
  • interpreter
  • editor
  • run-time environment
  • truth table
Multiple choice1 mark

Why can the CPU not execute the studio's Python source code directly?

  • APython has no variables or selection
  • BThe editor has not added comments
  • COnly low-level programs can contain errors
  • DIt is high-level source code rather than the CPU's machine code
Written answer4 marks

Explain two reasons why a high-level language is suitable while the studio develops the game.

Develop two separate characteristics into consequences for a team producing a substantial program.

Written answer4 marks

During development, explain two benefits of using an interpreter.

Link line-by-line translation to making changes and investigating errors.

Written answer6 marks

When the game is ready for players, explain three benefits of compiling it.

Consider distribution, later execution and access to source code.

IDE evidence from a development session

The programmer:

  • enters Python statements with line numbers and syntax colouring;
  • runs the game and sees its output;
  • receives a message identifying an error on line 18;
  • pauses at a breakpoint and watches score change;
  • converts the source program so it can be executed.

Several IDE facilities are working together. A strong response names the main IDE facility and then uses the observed action to explain what it does.

Written answer8 marks

Identify and describe four IDE facilities shown in the development session.

Identify four distinct IDE facilities and match each one to evidence in the scenario.

Students type their answer here.

Written answer5 marks

A student writes: ‘A compiler is better because it is faster and an IDE fixes all errors.’ Evaluate this statement.

Separate the two claims. Replace vague language with conditions and limitations, then reach a judgement.

Students type their answer here.

Written answer4 marks

The studio later writes a tiny time-critical controller for one fixed piece of game hardware. Explain why a low-level language could now be considered.

Link two low-level characteristics to this changed requirement.

Students type their answer here.

Final review

You should now be able to compare language levels, explain why translation is needed, recommend a compiler or interpreter for a stage of development, and describe how every required IDE facility helps a programmer.

Check every longer response for three things: a named point, an accurate explanation of how it works and a link to the given scenario.
