VC is a very easy-to-use C ++ programming tool of Microsoft. Its biggest advantage is that it is a very practical MFC (Microsoft basic class library) for programmers ), understanding and using MFC will bring a very high development efficiency to C ++

Each time you create a transaction object, you must create an appropriate record in the audit log. The following is a reasonable practice: Class transaction{Public:Transaction (){Init ();}Virtual void logtransaction () const {STD: cout
