Epic Skills Assessment Fictional Programming Language Logic 3

Question 1

In FictoScript, what is the output of `let y := 5; y := y * 2; print(y)`?

Accepted Answer

10

Answer

`let` in FictoScript declares a mutable variable, so reassignment is allowed, and y becomes 10.

Question 2

A FictoScript `match` expression that has no matching case and no `default` branch will:

Accepted Answer

Throw a MatchError at runtime

Answer

Without a `default` branch, a FictoScript `match` that finds no matching case raises a MatchError.

Question 3

In FictoScript, what does the `@pure` annotation before a function declaration guarantee?

Accepted Answer

The function has no side effects and always returns the same output for the same input

Answer

`@pure` marks a function as referentially transparent — no side effects and deterministic output.

Question 4

Which FictoScript scope rule applies to variables declared inside a `loop` block?

Accepted Answer

They persist across iterations but are destroyed when the loop ends

Answer

Loop-block variables in FictoScript persist across iterations but go out of scope when the loop terminates.

Question 5

In FictoScript, the `fold` function applied to a list processes it by:

Accepted Answer

Accumulating a single value by applying a binary function from left to right

Answer

`fold` reduces a list to a single accumulated result using a binary function applied sequentially.
