questions about lists on c++

Consider a List of strings that contains the following strings in the order given:

"bob" "ann" "sue" "ned":   [0]   [1]   [2]   [3] respectively

Give the contents of the List after each operation.

a. list.insert(2, "bob");
b. list.insert(5, "ann");
c. list.remove(0);
d. list.remove(3);

I got...bob, ann, bob, sue, ned;
 bob, ann, bob, sue, ned, ann;
ann, bob, sue, ned, ann;
ann, bob, sue, ann

is this correct?
