TCP (Transmission Control Protocol): responsible for connecting to the remote host IP (Internet Protocol): responsible for addressing and sending packets to the location where they are located IP Address: it is the logical address used by the network layer of TCP/IP to identify hosts in the network. It can uniquely identify a host in Interent. An IP address is a 32-bit binary address. Each IP address is divided into four segments (eight bits per segment). An IP address consists of a network addr

What happens if Class A inherits Class B, implements interface C, and Class B and interface C define variables with the same name. (instantaneous) Interface A {int x = 0;}Class B {int x = 1;}

Recently in the OPENCV-based license plate recognition, which requires some code for deep learning (python), the development language at the outset chose Python (the source of the scourge).Although the speed of Python is not too slow now, but you must use Python to manipulate the image, when implementing some algorithms, efficiency becomes very important. Unfortunately, Python in most implementations of the algorithm, because its loop operation is too slow, resulting in the implementation of the

C + + base class and derived class conversionsIn public inheritance, in private inheritance and protection inheritance, only public inheritance can preserve the characteristics of the base class, it retains all members of the base class except constructors and destructors, a

I. Class Declaration // A class is a user-defined type. The declaration form is as follows:Class Name{Public:Public Member (external interface)PRIVATE:Private memberProtected:Protect members}; After the public keyword, declare that they are class and external interfaces. Any external function can access public data and functions.After the keyword private is decla

Objective-C is a class-based object-oriented language. Each object is an instance object of a class. The isa pointer of the object points to the class corresponding to the object. Class describes the object data: memory allocation size, variable (ivar) type and layout.

accumulated run time value is frozen. Use the Reset method to clear the cumulative elapsed time in an existing Stopwatch instance.The Stopwatch counts the ticks in the base timer mechanism to measure elapsed time. If the installed hardware and operating system support counters for high-resolution performance, the Stopwatch c
