Who can help solve a string copy problem with list?

[djwinter]

I can not type chinese now, so use english instead

list <std::string A>
list <std::string B>

we have sucessfully read a file into A, for example,
stream a like : 1 2 3 4 5 6 7 8

now I want to copy "2 3 4" to B, how can I apply this?

[ddstudent]

list <string> A;
list <string> B;

B.assign(iteratorA_start, iteratorA_end);

which iteratorA_start is the iterator of element 2 in A and iteratorA_end is the iterator of element 4 in A

thanks a lot, is there any reference to find out the STL functions, to be honest, I have not idea about what function it is got.
