LESSON 17 OF 52 · CHAPTER 02

Decisions

if, elif, else and short-circuit guards

ORIGINAL SOURCE

01-decisions.srp

// Conditions are booleans; each body introduces a lexical scope.
bind score = 73;
var grade = "pending";
if score >= 90 {
    grade = "A";
} elif score >= 60 and score < 90 {
    grade = "B";
} else {
    grade = "C";
}
print(grade);
if true or 1 / 0 == 0 {
    bind message = "Selected safely.";
    print(message);
}
EXPECTED OUTPUT

stdout

Verified
B
Selected safely.

UNDERSTAND THE CODE

Explanation & practice

What this example teaches

if, elif, else and short-circuit guards

Expected behavior

Chooses a grade and prints a branch message

Practice: Read the source before looking at the output. Predict the values and their order, then use the pinned compiler to execute this lesson and compare the exact fixture. Identify which operation produces the result.

if, elif, else

शर्तों की क्रम से जाँच की जाती है। score के आधार पर grade चुना जाता है; दूसरी शर्त में and है।

अभ्यास: 73 अंकों के लिए कौन-सी शाखा चलेगी?

Which grade is printed when score is 73?जब score का मान 73 है, तो कौन-सा ग्रेड प्रिंट होगा?

Reveal the source-backed answer / सही उत्तर देखें

B — 73 does not satisfy score >= 90, but it satisfies score >= 60 and score < 90, so grade becomes B.B — 73, 90 से कम और 60 से अधिक या बराबर है। इसलिए elif की शर्त सही होती है और grade का मान B बनता है।

TRY IT LOCALLY

Verify, then execute

Use the pinned compiler from the course root. Keep any imported _support files next to the source.
