第17行使用member function的方式overload + operator,18行使用global function的方式overload * operator,這兩種寫法都可以,惟若使用global function,由於要存取data menber,所以要宣告該function為friend,這樣才能存取data member。 19行我們overload了<< operator,由於也是global function,所以也要宣告friend。 最後49行...

Operator overloading is another feature I could have used but didn’t. Whenever the compiler sees such an operator, it simply replaces it with the appropriate function call. So in the code listing that follows, the last two lines are equivalent and the performance penalty is easily understood...
也可以使用 shared_ptr overloads of atomic functions来防止race condition的发生。 多个线程同时读同一个shared_ptr对象是线程安全的,但是如果是多个线程对同一个shared_ptr对象进行读和写,则需要加锁。 多线程读写shared_ptr所指向的同一个对象,不管是相同的shared_ptr对象,还是不同的shared_ptr对象,也需要加锁...
