Understanding do-while Execution

A do-while loopexecutes at least oncebefore checking the condition.

++counter < 3 increments counterbeforeevaluating the condition.

Step-by-Step Execution

Iteration 1:counter = 0, print "0", then ++counter becomes 1, condition 1 < 3 istrue.

Iteration 2:counter = 1, print "1", then ++counter becomes 2, condition 2 < 3 istrue.

Iteration 3:counter = 2, print "2", then ++counter becomes 3, condition 3 < 3 isfalse, so loop exits.

Final Output

0 1 2

Thus, the correct answer is:0 1 2
