Reading Notes Objective c ++ Item 44 extracts code irrelevant to template parameters and implements tiveitem1. using a template may result in code Expansion
Using templates is a good way to save time and avoid code reuse. You do not need to manually enter 20 identical class names. Each class has 15 member functions. Instead, you only need to enter a class template, then let the compiler instantiate 20 specific classes and 300 functions you need for yo

Java record-44-Object array trapBelow is a very simple program, but there are unexpected traps:
public static void main(String[] args) { ArrayList list = new ArrayList(); list.add(new Integer(1)); list.add(new Integer(2)); // Integer[] ins = (Integer[])list.toArray(); Object[] ins = list.toArray(); for(int i=0;i
The above program can be executed, no problem. However, the annotated line of cod
pointer to the data, but it can result in a reduced encapsulation (Item 22). It can also lead to resource management complications: If the base class stores pointers to matrix data, but the data is either dynamically allocated or stored in derived class objects (as we see), how do you decide if you need a delete pointer? There is an answer to this question, but the finer things you do, the more complex it becomes. In a sense, a little bit of code repetition starts to get a little lucky.2.3 How

In order to complete the compilation first, the following steps are required:1. Go to the Linux subdirectory and perform make. (This step is patching.) )2, return to the previous level directory, open file simplec.c, add header file #include 3. Remove static from the static void set_address in the following file:Connectto.cTcpsink.c3. Perform make at the root directory.Carries mistake one:When doing Shutdownc/tcpecho experiments, the client SHUTDOWNC always outputs an error:Shutdownc:fputs faile
seed caused performance degradation, after JDK7, you can use Threadlocalrandom to get the random numberExplain the reasons for the performance degradation caused by competing with one seed, for example, look at the Nextint () method implementation of the Random class:The next (int bits) method is called, which is a protected method:And this side of seed is a global variable:When multiple threads acquire random numbers at the same time, they compete for the same seed, resulting in reduced effici

And as long as it stores those things, it is possible to store the matrix size:This allows derived classes to determine how memory is allocated. Some implementation versions may store the matrix data inside the Squarematrix object:TemplateThere is also a method of modification:TemplateThe aboveThe practice is to put the data for each matrix in
