Assign different labels based on a score using if/else.

Declare variable, assign in each branch:

  label <- "Unknown"
  if score > excellentThreshold
    label: "Excellent"
  else if score > goodThreshold
    label: "Good"
  else
    label: "Needs work"

EK9 has no return. Assign in each branch using the : operator. See Q1146 for if-guard.

Example

defines module qa.controlflow.ifelsevalue

  defines program

    IfElseValueDemo()
      stdout <- Stdout()

      excellentThreshold <- 90
      goodThreshold <- 70

      scores <- [95, 85, 72, 60]

      for score in scores
        label <- "Unknown"
        if score > excellentThreshold
          label: "Excellent"
        else if score > goodThreshold
          label: "Good"
        else
          label: "Needs work"
        stdout.println(`Score ${score}: ${label}`)

Common mistakes

E01072 — EK9 has no return statement. Declare a variable before the if/else and assign in each branch.

Incorrect:

if score > 90
        return "Excellent"

Correct:

        label <- "Unknown"
        if score > excellentThreshold
          label: "Excellent"

Other ways to ask this

Write code to categorize a numeric score into grade labels
I have a score and need to assign Excellent, Good, or Needs Work based on thresholds
Given a score from 0-100, produce a text label based on ranges
In Java I'd use if/else if/else to assign a grade. Write the EK9 equivalent

Coming from another language?

Java: if/else if/else with return. Python: if/elif/else. Rust: let label = if { } else { }. EK9: declare variable, then assign in each branch.

Keywords: grade, label, branch, score, assign, if, threshold, else
