Use of freopen functions (getting standard input and output streams from files) and freopen Input and Output When solving acm problems, we usually need to run the program in the debugging environment (such as VC) after designing the algorithm and program, input the test data, and obtain the correct running result, submit the program to oj.However, debugging often fails at a time, and test data must be re-input during each operation. For questions with

Socket transmission of protobuf byte streams by unity Explorer (4) and unityprotobuf Copyright:This article is the original article, reprint please declare http://www.cnblogs.com/unityExplorer/p/7027659.html I have already mentioned socket transmission in the previous article. This article mainly talks about reconnection due to disconnection. There is nothing to say. Just go to the code. 1 // I use a coroutine for the reconnection function, and it is

reason, it is recommended that files opened in text file mode always use the first prototype of SEEKG and SEEKP, and do not modify the return value of Tellg or TELLP. For binary files, you can use these functions arbitrarily, and there should be no unexpected behavior generated.In binary files, using Write (char * buffer, streamsize size);Read (char * buffer, streamsize size);Let me show you the following example:Output:FStream Deadaccountfile ("DeadAccount.dat"Ios::inch| Ios:: out|ios::binary)

sequence of bytes. GetByteCount is overloaded. When overridden in a derived class, calculates the number of bytes produced by encoding a set of characters. GetCharCount is overloaded. When overridden in a derived class, calculates the number of characters produced by decoding a sequence of bytes. Getdecoder When overridden in a derived class, gets a decoder that converts an encoded sequence of bytes into a sequence of characters. Getencoder When overridden in a derived class, gets a decoder t

1. first, let's take a look at several concepts, such as "Events", "event streams", "event names", and "event processing functions/event listening functions ", you can know your friends.Events: events are specific actions performed by users or browsers. For example, user clicks are commonly used click events.Event stream: Multiple events are triggered in a certain order to form an event stream.Event name: As mentioned above, click is the event name.Th

about an object, making the object persistent.Precautions for use:1. If you want to write an object to disk, then the class that the object belongs to must be serialized, implement the Serializable interface, serializable interface is not any method, is a tag interface2. If the object belongs to the class member variable changes, you read the original object is an error, if you want to resolve the error, ensure that Serialversionuid is unique.3. If you do not want to save some information to di

FileInputStream and FileOutputStreamCreates an input-output stream object with a disk file.FileInputStream inherits from InputStream, which is used to read byte data from local files, because all files are byte-oriented, so this class is suitable for manipulating any type of file.Construction Method:Example: FileInputStream FileInputStream = new FileInputStream (new File ("path"));Other methods:Read () Method: reads up to b.length bytes of data from the input stream into a byte array, returning

follows:#include The result of the above code operation is as follows:This is equivalent to splitting a sentence into words, referring to the method of reading the string from the file mentioned earlier, if the string object being read is a sentence and contains many words, then we can use this method to split the string object.2, the use of OstringstreamOstringstream is also constructed from a string object, and the Ostringstream class inserts a character into a string.#include The results of

Random Access:Seek (offset[, whence]): Moves the current position (where it is read and written) to the location defined by offset and whence. Offset indicates that the offsets must be non-negative. Whence: The default of 0 indicates that the offset is calculated from the beginning of the file. The whence is set to 1 (moves relative to the current position, at which poi
