⑴ 求一篇c++編程介紹的英語作文

The computer was born early, people to use computer to program in machine language or assembly language. The world's first computer advanced language was born in 1954 in FORTRAN language. After the emergence of a variety of advanced computer language, one of the most widely used, the greatest impact when pushing the BASIC language and C language. BASIC language is the two professors in 1964 by Dartmouth John G. Kemeny and Thomas E. Kurtz simplified into the basis of FORTRAN language, suitable for beginners of small high-level language design; C language is developed by Baer in 1972 American laboratory in D.M.Ritchie, using structured programming methods, follow the principle of top-down. [1] in the operating system and system using the program as well as needed to operate the hardware settings, using C language is obviously better than other high-level languages, but in writing large programs, C language is still facing challenges.
In 1983, on the basis of C language of the Baer laboratory Bjarne Stroustrup launched C++. C++ further expansion and improvement of the C language, is a kind of object-oriented programming language, the popular C language version.
The origin of the name
The name C++ Rick Mascitti in 1983 proposed, and was first used in 1983 December. Earlier, is still in the development stage of language has been called the "new C", then "C with Classes" is [2]. In computer science, C++ is still called the upper structure of C language. It finally gets its name from the C language in the "+ +" operator (the increment of the value of a variable). But in the naming conventions in common, use "+" to denote the enhancement program. Stroustrup said: "this name represents the natural evolution from C language change".
Note: C+ is the early programming language a and C/C++ independent.
Rick Mascitti has been informally asked about the origin of the name in 1992, which he said was spoken in half make fun of. He never thought C++ would become the official name of the language. A C++ name joke, when you use the suffix + +, additional occurs only in the computation (and hence, it should be ++C, but not C++, the joke is that nowadays some programmers to use C way to use C++, which is usually some authority is not true).
Development history
In "C with Class" stage of development, features of the C language based on the added are: class and a derived class, shared and private members, the distinction between class constructor and destructor, friend, inline functions, the assignment operator overloading.
Published in 1985, added the C++ language version 1 in the content of some important characteristics: the concept, function and operator overloading, virtual function reference, constant (constant) etc..
Launched in 1989 2 edition to form a more perfect support object-oriented programming language C++, the addition of new content including: protected members of a class, multiple inheritance, object initialization and assignment of recursive mechanism, an abstract class, static member function, the const member function.
In 1993 3 of the C++ language version is the C++ language to further improve, the new feature is the most important template (template), in addition to the problem of ambiguity of the two generation of multiple inheritance and the corresponding constructor and destructor disposal solution.
In 1998 the C++ standard (ISO/IEC14882 Standard for the C++ Programming Language) by the international organization for Standardization (ISO) and American Standards Association (ANSI) approval, the standard C++ language and standard library more embodies the C++ language, the original intention of the design. The concept, the standard template library name space (STL) standard container class, increase the general class of algorithms and string types that C++ language is more practical. Since C++ is an international standard programming language, the standard is usually referred to as ANSI C++ or ISO C++ 98 Standard, every 5 years as a standard update actual needs.
Later in 2003 passed the C++ version second (ISO/IEC 14882:2003): this new version is a technical revision of the first edition, collation -- Amendment error, rece the ambiguity, but did not change the language characteristics. This version is often referred to as the C++03. [1]
Since then, the new draft standards called C++ 0x. For the final C++ 0x draft standard international voting ended on August 10, 2011, and all countries had cast votes, C++0x has be beyond all doubt to become the official international standard. Previously was temporarily named new standard C++0x formally known as ISO/IEC 14882:2011, ISO C++ 11. The C++ 11 standard will replace the current C++ standards C++98 and C++03. The international organization for Standardization in September 1, 2011 published by the "ISO/IEC 14882:2011", the name is: Information technology - Programming languages - C++ Edition: 3

⑶ 編程怎麼學。

如何學習編程，主要有自學和報班兩種途徑，至於需不需要報班，可以結合自己的實際情況來進行判斷，這里簡單介紹下。

學編程的注意點：

1、要確定好自己一定能學下去，不能是三分鍾的熱度，只是學個熱鬧，這樣永遠沒有辦法學的會。

2、一定要打好基礎，剛開始學習編程的時候可能會很慢，感覺自己沒學會啥，這可能是因為正處於打基礎的階段，只有把基礎打好，未來才可以學得更好。

3、要注意實踐操作，理論知識學得再多，如果不能實際的運用，還是等於0的。

自學還是報班：

1、如果你可以規劃好自己的學習過程，堅持一步步向前走，那麼自學當然是很好的。

2、如果你沒人監督就學不進去，也沒有自己的學習規劃，那麼還是建議你報班，可以少走冤枉路。

不管是自學還是報班，學編程的要注意的點是相差不大的，希望我的回答對你有幫助！

⑷ 求一篇PLC編程的論文

PLC可編程技術論文 可編程式控制制器(Programmable Controller)是計算機家族中的一員，是為工業控制應用而設計製造的。早期的可編程式控制制器稱作可編程邏輯控制器(Programmable Logic Controller)，簡稱PLC，它主要用來代替繼電器實現邏輯控制。隨著技術的發展，這種裝置的功能已經大大超過了邏輯控制的范圍，因此，今天這種裝置稱作可編程式控制制器，簡稱PC。但是為了避免與個人計算機(Personal Computer)的簡稱混淆，所以將可編程式控制制器簡稱PLC。 PLC是一種專門為在工業環境下應用而設計的數字運算操作的電子裝置。它採用可以編製程序的存儲器，用來在其內部存儲執行邏輯運算、順序運算、計時、計數和算術運算等操作的指令，並能通過數字式或模擬式的輸入和輸出，控制各種類型的機械或生產過程。PLC及其有關的外圍設備都應該按易於與工業控制系統形成一個整體，易於擴展其功能的原則而設計。 PLC的特點：1可靠性高，抗干擾能力強。2硬體配套齊全，功能完善，適用性強 。3易學易用.4系統的設計、安裝、調試工作量小，維護方便，容易改造 .5體積小，重量輕，能耗低 . 一、 當代PLC技術的發展趨勢 發展迅速，產品更新換代；開發各種智能化模塊，不斷增強過程功能；PLC與個人計算機（PC）結合；通信聯網功能不斷增強；發展新的編程語言，增強容錯功能。 二、 當代PLC技術的發展動向 美國通用汽車以用戶身份提出新一代控制器應具備十大條件，這十大條件是： 1. 編程方便，可在現場修改程序； 2. 維修方便，最好是插件式； 3. 可靠性高於繼電器控制櫃； 4. 體積小於繼電器控制櫃； 5. 可將數據直接送入管理計算機； 6. 在成本上可與繼電器控制競爭； 7. 輸入可以是交流115V； 8. 輸出為交流115V/2A以上，能直接驅動電磁閥； 9. 在擴展時，原有系統只要很小變更； 10. 用戶程序存儲容量至少能擴展到4K位元組。 可編程式控制制器PLC中有多種程序設計語言，它們是：梯形圖語言、布爾助記符語言、功能表圖語言、功能模塊圖語言及結構化語句描述語言等。 目前，PLC應用人才供應主要依靠高校（設相關專業的有267所）、高職（600多所）和技校（2000多所）。其相關的專業一般名為「自動化」、「機械製造及自動化」、「電氣自動化」和「機電一體化」。 21世紀，PLC會有更大的發展。從技術上看，計算機技術的新成果會更多地應用於可編程式控制制器的設計和製造上，會有運算速度更快、存儲容量更大、智能更強的品種出現；從產品規模上看，會進一步向超小型及超大型方向發展；從產品的配套性上看，產品的品種會更豐富、規格更齊全，完美的人機界面、完備的通信設備會更好地適應各種工業控制場合的需求；從市場上看，各國各自生產多品種產品的情況會隨著國際競爭的加劇而打破，會出現少數幾個品牌壟斷國際市場的局面，會出現國際通用的編程語言；從網路的發展情況來看，可編程式控制制器和其它工業控制計算機組網構成大型的控制系統是可編程式控制制器技術的發展方向。目前的計算機集散控制系統DCS（Distributed Control System）中已有大量的可編程式控制制器應用。伴隨著計算機網路的發展，可編程式控制制器作為自動化控制網路和國際通用網路的重要組成部分，將在工業及工業以外的眾多領域發揮越來越大的作用
