FC0-U71 Practice Question: A developer writes a script to calculate the…
A developer writes a script to calculate the average of a list of numbers. The script uses a loop to sum the numbers and then divides by the count. Which programming concept does this represent?
⚠ Common exam trap
A common mix-up: candidates confuse 'sequence' (the general order of steps) with 'iteration' (the repeated execution of a block), especially since the script does follow a sequence of steps, but the key distinguishing concept is the loop that repeats the summing operation.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Iteration
The script uses a loop to repeatedly access each number in the list and add it to a running total. This repeated execution of a block of code (the loop body) is the defining characteristic of iteration. Iteration is the correct programming concept because the average calculation depends on cycling through a sequence of elements, which is exactly what a loop provides.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Iteration
Why this is correct
Iteration uses loops to repeat actions, as in summing numbers.
- ✗
Selection
Why it's wrong here
Selection involves decision-making (if-else), not loops.
- ✗
Recursion
Why it's wrong here
Recursion involves a function calling itself, not a simple loop.
- ✗
Sequence
Why it's wrong here
Sequence is simply executing instructions in order, but the key here is repetition.
