I have the following review question.

A list contains the values 30,40,60 in that order.

p&q are iterators that point to integers on the list.

What will the following print?

I think it is 40. p initially starts at 30 then increments to 40. q then inserts 20 as the value. p then goes back to the beginning of the list (30) and increments to the next value (now 20). Am I right? The thing that is hanging me up is wondering whether or not the value of p is updated by p++ or if it stays 30 (then the output would be 50). ThanksCode:p = intlist.begin(); p++; q = intlist.insert(p, 20); p = intlist.begin(); p++ cout << *p + *q;
