I. Why use Operator Overloading?For all operators of the system, generally, only the basic data types and classes provided in the standard library are supported. for user-defined classes, if you want to support basic operations, such as comparing

The sqlite3_exec introduced in the previous article uses a callback to perform operations on the select result. You must declare a function. If this function is a class member function, you have to declare it static (ask why? This is the basis of C +

All functions designed by you but called by the Windows system, collectively referred to as the callback function. Some API functions require callback as one of your parameters. Such as settimer, linedda, and enumobjects. Callback functions are

Class encapsulated driver The preceding clsint is too simple to answer the following question: what are the benefits of using classes in the kernel? The simclass project cannot answer the above questions. I just use it to solve some basic problems.

These days, we have just begun to learn the object-oriented programming of MATLAB. The previous thing is to use MATLAB to write some simple script or function, this aspect of MATLAB mature function and straightforward matrix operation method and

In C ++, member pointers are the most complex syntax structures. However, it is widely used in event-driven and multi-threaded applications to call-back functions. In multi-threaded applications, each thread calls this function by pointing to a

Compiling firewall-parsing Pimpl usage in C ++ Pimpl(Pointer to implementation, pointing to the implemented pointer) is a common method used to decouple "class interfaces and implementations. This technique avoids exposing private details in header
