Question
One or more of the following statements could be true. Tick the true statements and leave the
false statements unticked. You get full marks only for correctly denoting each statement as
true/false by ticking/leaving unticked respectively. There are no partial marks.
O The reference value passed as argument to func1 in line 11 is the same as the reference
value passed as argument to func2 in line 16.
O The output of the program is 30333633303630.
O Line 09 creates an object that is a copy of the object created in line 08.
O Line 19 prints the value of the member variable n of the object referenced by t1.
