The second step should be to stop the technical aspects. Let's take a look at the practice of programming of Pike and kernighan, and sort out the precautions in programming. This very thin booklet is a must-read guide for programmers.
The third book, written by Bruce Eckel, is the thinking in C ++ translated by Hou Jie. I will re-read this book every six months. It can be said that each chapter is thought-provoking. This book makes me feel that the technology is used in a very high

limited to our C ++ knowledge level and programming skills, in the implementation process certainly has not noticed the place or even the defect, hope to be able to get everyone's correction, my email is hcode@21cn.com.
Based on the memory detection subsystem we have implemented, we can continue to build a memory allocation optimization subsystem to form a complete memory subsystem. The implementation scheme of a memory allocation optimization subsystem is to allocate a large amount of memory

version. These functions are: A copy constructor, a value assignment operator, a destructor, and a pair of access operators. In addition, if you do not declare any constructor, it will also declare a default constructor for you. All these functions are public. In other words, if you write:Class Empty {};This is the same as writing:Class Empty {Public:Empty ();Empty (const Empty rhs );~ Empty ();Empty operator = (const Empty rhs );Empty * operator ();Const Empty * operator () const;};Some re
Static or global variables
C ++ cannot guarantee the calling sequence and destructor sequence of the constructors of static or global objects. Therefore, if there are multiple Singleton classes implemented using this method in the program, there is another constructor dependency and destructor dependency between them, which will cause disastrous consequences. Therefore, this implementation is appropriate only when there is certainly no constructor or destructor dependency.

of a memory allocation optimization subsystem is to allocate a large amount of memory at a time and manage it using a specific data structure. When memory allocation requests arrive, A specific algorithm is used to define a required part of the large memory for the user. After the user completes using the algorithm, it is classified as idle memory. This memory optimization method converts memory allocation and release into simple data processing, greatly reducing the time required for memory ap

-assignment issues can participate in effective C + + clause 11)The above example uses the copy and swap technique to define the assignment operator as follows:hasptr hasptr::operator=(hasptr rhs) { swap (*this, RHS); return *this;}It can be seen that, unlike the general assignment operator, its arguments are in the way of passing values , not references. It is functionally equivalent to the following code, but is more efficient (moves the copy action to the function parameter constructio
