Synopsis
# Include
Size_t fread (void * PTR, size_t size, size_t nmemb, file * stream );
Size_t fwrite (const void * PTR, size_t size, size_t nmemb,
File * stream );
The function fread () reads nmemb elements of data, each size bytes
Long, from the stream pointed to by stream, storing them at the loca-
Tion given by PTR.

In Python, there are two variable-length parameters, the tuple (non-keyword argument) and the dictionary (keyword parameter), whose parameters represent an arbitrary-length tuple [tuple] at the beginning of a *, and can receive successive strings of arguments, with the argument starting with two * to represent a dictionary [dict], or "key:value , accept any number of consecutive arguments.

of our designs. In some cases, we can test the options with small sample users, like the prototype test for my TV page mentioned above. For other situations, like verifying the use of sidebar navigation, you need to look at the actual usage records of a large number of users. At this point, we need to use A/b Test.
For A/b test for mobile applications, we use swrve--, the most mature A/b test tool in my opinion, which not only provides goal seeking (when the winning solution is clear, A/b test

range with the line of the two ears of the listener as the axis.The role of the ear filter is to strengthen/weaken the acoustic energy from different angles of the sound, filter it and send it to the brain, so that we can more accurately position the sound source. The size of the ear is limited, so the range of received audio waves is limited, usually 20Hz to 20 kHz, that is, the wavelength of 16 meters to 1.6 cm of the audio wave. In other words, below this range is the secondary acoustic wave

iterators often refer to each other.GeneratorThe main purpose of the generator (generator) is to make up a user-defined loop object.The generator is written in a similar way to the function definition, except that it is changed to yield in the return place. There can be more than one yield in the generator. When the generator encounters a yield, it pauses to run the generator, returning the value after yield. When the generator is called again, it will continue to run from where it was just pau

Perhaps the poor base of the reunion asked before the string lo= ""; why, because each lo will point

Examples are as follows:Myrunnable runnable = new myrunnable (); Thread thread = new Thread (runnable, "new Thread"); Thread.Start (); System.out.println (Thread.getname ());It is important to note that because Myrunnable is not a subclass of thread, the Myrunnable class does not have a getname () method. You can get a reference to the current thread in the following ways:Thread.CurrentThread ();Therefore, the name o
