I. pointer ConceptThe pointer is the address in the memory.1. Syntax: type * variable nameThe type here defines the variable type pointed to by this pointer.2. pointer operators (* and &) & get the address OperatorFor example:Int counta = 100;Int *

A few days ago, I saw such an article on vckbase. Now I want to imitate it to implement this function [quote]. With the development and popularization of computer technology, computers have gradually entered people's daily life. People use it to

It is not important to get started with a language, but a good programmer should at least master a language, and it is best to be "proficient! C ++ has a large user base, rich learning resources, and broad application prospects. Therefore, many

Haiming code Verification Program Design 1. Requirement Analysis 1) Haiming code:Input: a string of binary dataOutput: the binary data string after the Hamming code is inserted. 2) hamming code error correction:Input: a string of binary data strings

4.6 use third-party LibrariesThe preceding section describes how to assign values to, convert, and convert character codes to Visual C ++. In fact, there are some useful third-party class libraries to help C ++ programmers complete object processing,

Boost: lexical_cast is a conversion between values. For example, to convert a string "123" to an integer 123, the Code is as follows: string s = "123";   int a = lexical_castint>(s);  This method is very simple. I strongly recommend that you

Qt is a famous C ++ library. It may not be said that it is just a GUI library, because Qt is very large and not just a GUI. Using Qt, you get a "one-stop" service in a certain program: you no longer need to study STL or C ++ , because Qt has its own

Eclipse CDT Environment ConstructionThe standard C ++ environment is not easy to handle. Many developers choose VS, but it is not suitable for coding other operating systems, besides, VS supports a non-200 Standard C ++. And bulky. The following

First of all, in C ++ GUI Programming with Qt4, 2nd, this chapter, together with several subsequent chapters, completed a relatively complete Program-a spreadsheet that imitates Excel. However, this program is big, and the complete source code is

I have written 15th articles on the path to Qt learning, but it is a little difficult to write it again because I didn't expect it to be written continuously at the beginning, therefore, there is no good plan for writing such content. Although I

1. Replace values with values in C Language Preprocessor replace names: # define BUFSIZE 100C ++ replace values with const into the compiler field: const bufsize = 100; or const int bufsize = 100; you can also execute constant folding: char buf

More people support me! Some friends also suggested that the previous event-related tutorials lack examples. Because the event is hard to be used as an example, I didn't write it, but I just wrote about it. What we bring today is a new part about

Today's QTableWidget is the last items class type. However, this is not the end of model-view, because we are still only exposed to the simplest model-view encapsulation class, more complex and powerful model-view applications have not yet seen it!

The model-view section of Qt has come to an end. Today we will start a new section. Some friends may think that the previous section is very simple. There is no way for me to do this. After all, Qt is a very large library, and at half past one it

We mentioned the QByteArray class in the last section of QString. Now we will first introduce this class. QByteArray has APIs similar to QString. It also has corresponding functions, such as left (), right (), mid () and so on. These functions not

I plan to discuss with you one question: 1. How to sign the S60 3rd installer. In the end, we can develop the sis program at will. Many netizens have encountered this problem on the Internet: After developing a Symbian program, the SDK simulator

Speak with code ComTest implements two interfaces: ICmd, IStr, and ICmd. There is a function -- Add, and IStr has a function -- Cat, which is used to describe the usage of smart pointers, so it is not listed, the attachment contains the project code.
