LESSON 18 OF 52 · CHAPTER 02
While Loops
Counting, conditional skipping and early exit
02-while-loops.srp
// Iteration with nearest-loop control and checked accumulator arithmetic.
var index = 0;
var total = 0;
while index < 10 {
index += 1;
if index == 3 { continue; }
if index > 5 { break; }
total += index;
}
print(total);
stdout
12
Write what you expect this program to print. Check prediction for a line-level hint without revealing the answer, or reveal the verified output when ready. This checks displayed text only; it does not run Scarp or save your input.
UNDERSTAND THE CODE
Explanation & practice
What this example teaches
Counting, conditional skipping and early exit
Expected behavior
Prints the accumulated sum
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.
while, break, continue
while लूप शर्त सही रहने तक चलता है। continue वर्तमान चक्कर का बाकी भाग छोड़ता है; break लूप से बाहर निकलता है।
अभ्यास: कौन-से index total में जोड़े गए हैं?
Explanations are sourced from the project's English chapter guide and हिन्दी अध्याय. The Scarp program and output are unchanged.
SOURCE-BACKED SELF-CHECK · स्रोत-आधारित अभ्यास
Quick checkpoint / त्वरित अभ्यास
What total does the while loop print after skipping 3 and breaking above 5?3 को छोड़ने और 5 से ऊपर जाने पर लूप रोकने के बाद while लूप कौन-सा total प्रिंट करता है?
Reveal the source-backed answer / सही उत्तर देखें
12 — The loop adds 1, 2, 4 and 5. It skips 3 with continue and exits at 6, so the sum is 12.12 — लूप 1, 2, 4 और 5 को जोड़ता है। continue से 3 छूट जाता है और 6 पर break होता है, इसलिए योग 12 है।
