1. C + + Each stream object maintains a buffer, which is essentially a character array for storing input and output sequences, and is described by three pointers (Begin_pointer,next_pointer,end_pointer), which are divided into full buffers by the

Many people write C # code, often to call C + + code, sometimes we usually use the log to view the health of the state, which of course, but this is not convenient, run the code over and over again, I feel that if you can directly break into C + +

Really a good book, just so little, I feel a lot of learning, of course, I am too poor level.When using the shell or bash, there is a file redirection, that is, each time the program runs, we need to manually enter the content, and then the program

======================== Inline Function ======================Frequent calls to small functions make function calls more expensive, and code that does not apply to functions that do the same function directly in the program can reduce the

1, the basic use of the delegate, similar to the function pointer, but more secure than the function pointer, more powerful function. There are two ways to initialize a static function, or you can register a member function, and the invocation of a

6.6 DelegatesA delegate (delegate) is a type that can store a reference as a function. This sounds pretty tricky, but its mechanism is very simple. The most important use of a delegate can be explained later in this book, with events and event
