Step 1: Analyze loop body
Only the first statement after while is considered inside the loop without braces.
Step 2: Check increment position
x++ is outside the loop, so x never changes inside the loop.
Step 3: Consequence
This causes an infinite loop printing 0 repeatedly.
Final Answer:
The increment statement is outside the while loop block. correctly identifies the error.
