Read. Check. Build.

Three linked steps using real Scarp source and verified output.

  1. Read the lessons · पाठ पढ़ें

    Work through all 16 verified examples. Save optional local lesson progress as you learn; this does not certify code execution.

    Start with Hello ↗

    Lesson tracking is optional and only available when browser storage works.

  2. Check understanding · समझ जाँचें

    Try 3 bilingual questions linked directly to their original source and expected output. No quiz score is stored.

SOURCE-BACKED SELF-CHECK · स्रोत-आधारित अभ्यास

Quick checkpoint / त्वरित अभ्यास

What exact text does this first program print?यह पहला प्रोग्राम ठीक कौन-सा टेक्स्ट प्रिंट करता है?

Reveal the source-backed answer / सही उत्तर देखें

Hello from Scarp! — The source calls print with the string literal "Hello from Scarp!", so the fixture contains that line.Hello from Scarp! — स्रोत में print को "Hello from Scarp!" स्ट्रिंग दी गई है, इसलिए अपेक्षित आउटपुट में यही पंक्ति है।

Question 2 of 3 · Bindings · View source and recorded output ↗

SOURCE-BACKED SELF-CHECK · स्रोत-आधारित अभ्यास

Quick checkpoint / त्वरित अभ्यास

What number is printed for area after width = 6 and height = 7?width = 6 और height = 7 होने पर area के लिए कौन-सी संख्या प्रिंट होती है?

Reveal the source-backed answer / सही उत्तर देखें

42 — The binding area multiplies width by height: 6 × 7 = 42. The verified output prints 42 after the Area label.42 — area में width × height की गणना होती है: 6 × 7 = 42। सत्यापित आउटपुट में Area के बाद 42 प्रिंट होता है.

Question 3 of 3 · Mutable · View source and recorded output ↗

SOURCE-BACKED SELF-CHECK · स्रोत-आधारित अभ्यास

Quick checkpoint / त्वरित अभ्यास

After count is changed several times, what does the immutable original still print?count को कई बार बदलने के बाद immutable original का कौन-सा मान प्रिंट होता है?

Reveal the source-backed answer / सही उत्तर देखें

2 — original captures count when its value is 2. Later changes to count do not change original.2 — original में count का शुरुआती मान 2 रखा जाता है। बाद में count बदलने से original नहीं बदलता।
