Recently, I want to tidy up the history of computer language, read a lot of information about it, and draw a mind map, hoping to deepen the thinking and understanding of this aspect.First generation programming language is a machine-level programming language that is written in 1s and 0s. It does not need to be compiled and converted and can be used directly by the CPU. Using 1GL This code can be run quickl

What is functional programming (functional programming)? Functional programming is to write programs with functions. The answer is too abstract to say.And make it clear: functional programming is like building blocks, taking functions as blocks of blocks, outputting input functions as wedges and wedges, and combining t

Today's meeting referred to functional programming, for different types of Centennial City approach, access to a portion of the information, shown as follows:Programming language has been to modern times, from the Assembly to C to Java, are standing in the computer's perspective, considering the operating mode and operating efficiency of the CPU, in order to design an efficient programming language, as a br

13th Chapter Network Programming Network programming for many beginners, are very yearning for a kind of programming skills, but many beginners because for a long period of time can not enter the door of network programming to give up the part of the learning of technology. Before Learning Network

Problem Description: 0-1 Backpack: There are n items and a backpack with a weight of M. (Each item is only one) the weight of item I is w[i], value is p[i]. Solving which items are loaded into the backpack can make the sum of the greatest value. Dynamic planning: Dynamic programming algorithms are often used to solve problems with some of the best properties. There may be many possible solutions to such problems. Each solution corresponds to a value,

One, two main problems in network programming One is how to accurately locate the network on one or more hosts, and the other is to find the host after the reliable and efficient data transmission.In the TCP/IP protocol, the IP layer is mainly responsible for the location of the network host, the routing of Data transmission, the IP address can uniquely determine a host on the Internet.The TCP layer provides reliable or unreliable data transmission me

Programming can be seen as a branch of practical magic. Programmers use time and energy to make sacrifices and contract with the genie living in the computer in exchange for the ability to control code.--- Fmddlmyy To improve programming, you only need to read more and write more. This article seems like an experience, but the essence is to fill the water. This irrigation project draws up the following them

many unittest instances ). At the beginning, all unit tests failed because nothing was implemented. As small demand modules were completed, more and more unit tests were passed. In this way, both the customer and the developer can easily check whether the customer has fulfilled its commitment to the customer. XP advocates simple design, which is the simplest way to allow programs written for each simple requirement to pass all relevant unit tests. XP emphasizes abandoning the detailed design pa

Pingwu C-Abandon errors and bad habits in C Programming--Preface What kind of book is this? This is a book about common errors in C programming. The book analyzes and discusses in detail some common mistakes and practices in learning or using C language. The objective is to help readers better understand and use the C language. Why write such a book? Errors are inseparable from

13.2.4 UDP Programming Network communication In addition to the way the TCP, there is a way to implement the UDP way. UDP (user Datagram Protocol), the Chinese meaning is the Customer datagram protocol, similar to send short message, is a cheap way of communication, use this way without establishing a dedicated virtual connection, because no need to establish a dedicated connection, so the pressure on the server is much smaller than TCP , so it is al

Socket is a way of inter-process communication, and other processes of communication between the main difference is: to achieve inter-process communication between different hosts, the network of a variety of services are based on the socket to complete the communication, to solve the network of two host communication problems, the first to uniquely identify the process, In TCP/IP network protocol, it is through (IP address, protocol, port number) ternary group to identify the process, solve the

Feeling for the work of programming, I started to think so, or we are now good. For example, the language developed, developed into easier to understand and programming, tools also developed, programming time is more convenient, such as the current smart tips. But it seems a bit one-sided, and it's hard to really understand the history of a technology without und

Socket Basic Concepts: Sockets are the cornerstone of communication, and are the basic operating unit of network communication that supports TCP/IP protocol. Sockets can be viewed as endpoints of two-way communication between different host processes, which form the programming interface between a single host and the entire network. Sockets exist in the communication domain, which is an abstract concept that is introduced in order to handle a generic
