CHAPTER 03 · 4 LESSONS
03 · Functions
Learn the current compiler's typed function declaration syntax: funcra. Function parameters and return types are explicit. A pure funcra cannot perform effects such as output.

SOURCE-BACKED SELF-CHECK · स्रोत-आधारित अभ्यास
Quick checkpoint / त्वरित अभ्यास
What is the first number printed by add(10, square(5))?add(10, square(5)) से प्रिंट होने वाली पहली संख्या क्या है?
Reveal the source-backed answer / सही उत्तर देखें
35 — square(5) returns 25; add(10, 25) returns 35. The source calls these functions before their declarations.35 — square(5) का परिणाम 25 है। फिर add(10, 25) का परिणाम 35 होता है।

SOURCE-BACKED SELF-CHECK · स्रोत-आधारित अभ्यास
Quick checkpoint / त्वरित अभ्यास
What does fib(10) print in this recursive example?इस recursive उदाहरण में fib(10) क्या प्रिंट करता है?
Reveal the source-backed answer / सही उत्तर देखें
55 — The function returns n when n is at most 1 and otherwise adds fib(n - 1) and fib(n - 2); fib(10) is 55.55 — n का मान 1 या उससे कम होने पर फ़ंक्शन n लौटाता है; अन्यथा पिछले दो Fibonacci मान जोड़ता है। fib(10) = 55 है।

SOURCE-BACKED SELF-CHECK · स्रोत-आधारित अभ्यास
Quick checkpoint / त्वरित अभ्यास
What does clipped(x: 15) return with the default maximum of 10?डिफ़ॉल्ट अधिकतम 10 होने पर clipped(x: 15) क्या लौटाता है?
Reveal the source-backed answer / सही उत्तर देखें
10 — clipped uses defaults lo = 0 and hi = 10. Because x is greater than hi, it returns 10.10 — clipped में डिफ़ॉल्ट lo = 0 और hi = 10 हैं। x, hi से अधिक है, इसलिए फ़ंक्शन 10 लौटाता है।
