Step-by-Step Solution
Solution:
Step 1: Trace the loop iterations
Counter starts at 1, prints 1, then increments to 2, prints 2, increments to 3, prints 3, then increments to 4.Step 2: Check loop condition
Loop stops when counter is 4 because 4 <= 3 is false. So printed numbers are 1, 2, 3.Final Answer:
1 2 3 -> Option AQuick Check:
Prints 1 to 3 with counter increment = C [OK]
Quick Trick: Loop runs while counter ≤ 3, prints 1,2,3 [OK]
Common Mistakes:
MISTAKES- Including 4 in output
- Starting count from 0 instead of 1
- Printing numbers in reverse
