Simply call a function to gethostbyname (),gethostbyname () returns a hostent structure pointer to the host name and address information that corresponds to the given host name. The declaration of the structure is consistent with the GETHOSTADDR ().

It was a little early today, so I am writing an article. Continue with the previous article. Have we ever encountered such a situation during programming, the classes you define are only used to encapsulate related data, but do not need associated
Java 5 and later provide excellent concurrent libraries util. concurrent,. net lack similar functions. As the hardware system has changed and the multi-core era is approaching, the lack of concurrent class libraries in. NET is obviously out of date.
C ++ AMP: Parallel Computing On the GPU

I see all the young believers, your target audience. I see all the old deceivers; we all just sing their song.-Marilyn Manson, Target Audience (Narcissus Narcosis)
From CPU to GPU

Generally, a class has multiple constructors. Over time, the number of member variables and constructors has increased. The most convenient way to deal with this situation is to initialize the variable while declaring it, rather than in every
Hosting C ++ is. it advocates a new programming concept, so we can regard "hosting" as ". ", the C ++ application caused by the concept of hosting consists of three parts: hosting code, hosting data, and hosting.

DLLIt is short for Dynamic Link Library, which is a Dynamic Link Library. DLL files are generally stored in the C: WindowsSystem directory. DLL is a library that contains code and data that can be used by multiple programs at the same time.

C ++ from scratch (12) What is object-oriented programming idea Original Source: NetworkThe most important concept of C ++-class has been described above, and most of the class-related knowledge has been introduced. So far, we can start to do some
To serialize and deserialize the interface to XML, GacUI must have functions similar to reflection. However, C ++ has no reflection. The current method is to take out the compiled pdb file. Because the control is not a template class, data can be

First, make it clear:
The system has provided the default copy constructor and the = copy operator. That is, the so-called shallow copy.
But sometimes we have to provide our own rewrite. Generally, it is rewritten with pointers.
For a simple example,
A shuffling algorithm is provided and the cards are stored in an integer array. (IDEA 1)
The solution to this question is: store 1 to 54 cards randomly in an array of 54 sizes. The time and space complexity of this method are relatively
Using the C ++ one-way linked list to implement data structure queue is basically the same as the previous article. It is only inserted at the end of the linked list during insertion, and the elements are the same. They are all taken from the header.
