Step-by-Step Solution
Solution:
Step 1: Understand the loop execution
Thedo-whileloop runs the body first, printing $count starting at 1, then increments $count.Step 2: Trace each iteration
Iteration 1: prints 1, $count becomes 2
Iteration 2: prints 2, $count becomes 3
Iteration 3: prints 3, $count becomes 4
Condition $count -le 3 fails, loop stops.Final Answer:
1 2 3 -> Option DQuick Check:
Loop prints 1 to 3 [OK]
Quick Trick: Remember do-while runs once before condition check [OK]
Common Mistakes:
- Thinking loop stops before printing 3
- Confusing increment timing
- Assuming no output if condition false initially
- Mixing output order
