Record some of the things you read about this book.I. References (reference)The reference has a different name for the object. For example:int ival=1024;int relval1=ival;//to, attention try not to use this way:int relval=ival;int relval2;//error, reference must be initializedWhen a reference is defined, the program binds the reference with its initial value (binding) instead of copying the initial value to the reference. Once the initialization is complete, the reference will always be bound tog

own header fileThe generic class definition is placed in the header file. To allow the program to be separated into separate logical blocks, C + + supports the so-called separate compilation. This program can consist of multiple files2.9.1. Designing your own header filesHeader files typically contain the definition of a class, the declaration of an extern variable, and the declaration of a functionThe correct use of the header file can bring two benefits: Ensure that all files use the same dec

not empty when the file is opened with both in and out. If the file associated with FStream is opened, only the out mode is used and no in mode is specified, the file empties the existing data. If Trunc mode is specified when the file is opened, the file is also emptied, regardless of whether in mode is specified at the same time.4.2.2 Mode is a property of a file rather than a streamNote: Whenever you call the Open function, set the file mode, which can be either explicit or implicit.

philosophical ideas exist, recorded under the understanding of the Linux operating system philosophy.All documents (Linux almost all the resources are abstracted into the form of files, even the hardware, network communications using sockets and pipelines are so), the file is a set of boundaries in the storage device streaming data.Second, by a number of small functions of a single program, combined together can achieve complex tasks, each small program only do one thing, and to do a good job,

buffersThe following situations will cause the contents of the buffer to be flushed, that is, to write to the actual output device or file:(1) The program ends normally.(2) in some uncertain times, the buffer may be full.(3) Flush buffer with modifier explicitly type, such as line Terminator Endl. such as:cout(4) After each output operation is finished, set the internal state of the stream with the unitbuf operator. such as:cout(5) The output stream can be associated with the input stream.8.4 I

Exercise 9.26: If you have the following IA definition, copy ia into a vector container and a list container. Use the erase function of a single iterator parameter version to set the odd value of the list containerelement is removed and then the even values in the vector container are removed.Code:Summary: (1) When you define vector variables, you can initialize them with arrays;(2) The vector container returns an iterator to the next element after the element is deleted using the erase function

The so-called lightweight is relative to the heavyweight, lightweight refers to these draw2d drawing (figure) is a pure Java object drawn out, and the specific operating system resources are not directly linked.
