Booleans

Comparisons, boolean logic and short-circuiting

ORIGINAL SOURCE

05-booleans.srp

// Boolean values, checked comparisons, and readable short-circuit logic.
var ready = false;
bind score = 42;
ready = score >= 40 and score < 100;
print(ready);
print(not ready);
print("Scarp" == "Scarp");
print(false and 1 / 0 == 0);
EXPECTED OUTPUT

Explanation & practice

What this example teaches

Comparisons, boolean logic and short-circuiting

Expected behavior

true, false, true, false

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.

बूलियन और तुलना

true और false शर्तों के मान हैं। and, or और not का उपयोग होता है। शॉर्ट-सर्किट में अनावश्यक दूसरा भाग नहीं जाँचा जाता।

अभ्यास: false and ... वाले भाग में भाग-शून्य की गणना क्यों नहीं होती?

Explanations are sourced from the project's English chapter guide and हिन्दी अध्याय. The Scarp program and output are unchanged.

TRY IT LOCALLY

Verify, then execute

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