Six original Cambridge-style questions on integrated development environments, with mark-scheme solutions.

Keep these straight

Seven functions.

Write: code editor, auto-completion, auto-correction, prettyprint.
Translate: built-in compiler and/or interpreter.
Test and debug: run-time environment, error diagnostics.
For each: say what it does and how it helps the programmer.

Explain

[2 marks]

Explain the role of an integrated development environment (IDE) when writing program code.

An IDE is software that provides the tools a programmer needs in one place, ✓
to write, translate, run/test and debug program code. ✓

Recall

[4 marks]

Identify four common functions of an IDE.

Code editor. ✓
Error diagnostics. ✓
Auto-completion. ✓
Prettyprint. (Also accept: run-time environment, translators, auto-correction; one mark each, up to four.) ✓

Explain

[2 marks]

Describe how error diagnostics help a programmer.

They detect errors and show where they are, e.g. highlighting the line number. ✓
They describe what the error is, so the programmer can find and fix it quickly. ✓

Explain

[2 marks]

Describe the difference between auto-completion and auto-correction.

Auto-completion suggests how to finish a keyword or identifier while it is being typed. ✓
Auto-correction automatically fixes a mistake, such as a misspelt keyword, after it has been typed. ✓

Apply

[3 marks]

A student's code has inconsistent indentation and is hard to read. Name the IDE function that would help, describe what it does, and explain why this helps.

Prettyprint. ✓
It displays the code with consistent indentation and colour-coded keywords. ✓
This makes the structure (e.g. which statements are inside a loop) easy to see, so errors are easier to spot. ✓

Analysis

[2 marks]

An IDE contains both an interpreter and a compiler. Explain how a programmer might use each while developing and then releasing a program.

While developing, use the interpreter to run and test the code line by line, stopping at errors to debug them. ✓
When the program is finished, use the compiler to produce an executable file to release. ✓

Mark this once you have attempted all six and checked your working. It records a Practiced badge on the topic and adds a one-time bonus. Revealing the solutions alone does not count.
