get the length of the S string, you should use sizeof (S. c_str (), because the string member function c_str () returns the first address of the string. In fact, the string class provides its own member functions to obtain the capacity and length of the string, namely capacity () and length (). String encapsulates string operations, so it is best to use string to replace C-type strings during C ++ development. 8. view the CPU peer bounds from the sizeof problem of union Consider the following:

ASP for one month first. Third, using glassfish as a server is really easy to build. You don't have to worry too much about it, and there won't be different cases of different machines. Okay, so I started to build the platform. We first download the relevant software from the Oracle website. 1. JDK 6 (required) Http://www.oracle.com/technetwork/java/javase/overview/index.html 2.

following is the sorting code for testing. Here, the sorting is based on the attr2 and attr3 attributes of embedded object B of object. from operator import itemgetter, attrgettera1 = A(B('u1', 'AAA', 100))a2 = A(B('u2', 'BBB', 100))a3 = A(B('u3', 'BBB', 10))aaa = (a1, a2, a3,)print sorted(aaa, key=attrgetter('b.attr2', 'b.attr3'))print sorted(aaa, key=attrgetter('b.attr2', 'b.attr3')， reverse=True) Run the test and the result is as follows: [[u1, AA
