C++in theNested classes and local classesRecently took advantage of the Spring Festival holiday idle, find this C + + Primer learned a few chapters, found that many features of C + + do not know. nested classes and local classes feel pretty useful,

1. Open Source Library for C + + parsing xmlThe parsing of XML in the project uses an open-source third-party library,TinyXML; the model of this parsing library is generated in the XML file and then in memory DOM model so that we can easily traverse

In previous posts, the depth-first traversal of graphs was introduced, and recursive and non-recursive implementations were carried out respectively. BFS cannot be implemented recursively, and the most widespread implementation is the use of queues.

Rewrite requirement 1: Implemented with single-linked list#include #includeusing namespacestd;structlinknode{intdata; Linknode*next;};classpalindrome{intLow,up; inta[ -]; intcount; Public: Palindrome (intT1,intT2); intIspalin (intx);

Clause 20: Prefer to replace pass-by-value with Pass-by-reference-to-constBy default, the C + + function pass parameter is the way to inherit C, which is the value pass (pass by value). This passes through a copy of the actual argument, which is

Ten. Goto keyword in general, the level of encoding is inversely proportional to the number of times the goto statement is used. Personal Assertion, disable goto statement. one. void keyword 1. Void modifier

C # Call C++dll the ultimate solution for passing struct-body arraystime 2013-09-17 18:40:56 csdn blog Similar article (0) original http://blog.csdn.net/xxdddail/article/ details/11781003 In the project development, to invoke the C + +

in general, if there are N homogeneous objects, each object has its own data member, and the data members of different objects have their own values, which are irrelevant to each other. But sometimes people want to have one or several data members

Sequence (foreword)Some wonderful things are happening in the C + + community. Although C + + is still the most widely used programming language in the world, it is still becoming more powerful and easy to use. Do you believe me? Let me slow

1.The two-mesh operator is left-to-right Priority level Operator Name or meaning Use form Combination direction Description 1 [] Array subscript array name [constant expression]

This problem, sometimes a puzzle, is a time to comb through.Signed char->unsgned char:%c->%c 0->127 (corresponding range)char->int:%c->%d->%c, ' A '->65 (printable Character map)Short int->int:%d->%d,100->100 (corresponding, if the reverse operation

#ifndef, (or #ifndef), #def, #endif等宏这几个宏是为了进行条件编译. In general, all lines in the source program are compiled. However, sometimes it is desirable to compile a part of the content only if certain conditions are met, that is, to specify the conditions

The copy constructor is a special constructor with a single formal parameter, which is a reference to the class type, which is a common const adornment. Like the default constructor, copy constructors can be called implicitly by the compiler. The

C # open Source IM systemThe integration of the IM part of the system, extracted, a total of reference, but also as you can learn Networkcomms framework of a demoname : Breeze imName Source: Small means that the system is relatively simple　　　　　　The

XmlDocument and XElement are going to have to put the entire XML document into memory when reading XML, which is simple, but very costly to memory and IO (possibly disk IO or network IO), while in some scenarios we have to consider saving as much

The last time I wrote a file stream method to export a DataTable to Excel, this method has limitations, such as the inability to add to excel some simple operation of the column color, and now, to introduce another way to use Microsoft's Excel class.

6. EncapsulationEncapsulation is the hiding of members or variables from external classes. I have already said that the security of the House is confined to the entrance of the house and does not need to know what is going on inside the room. The

The project has been used many times to Excel operations, think of the need to summarize these methods, methods to be able to have a clear understanding of the overall, this article mainly discusses the use of C # for Excel operations, parsing three
