【正文】 32。使用匯編語言編程時，重要的是要盡量減少所花費的時間運行程序，因為從匯編語言翻譯成機器語言是比較簡單。匯編語言與機器語言共享某些特征。在一個匯編語言，每個語句大致相當于一臺機器語言指令?；谶@個原因，方案寫在一個高層次的語言可能需要更長的時間來執(zhí)行和使用更多的內(nèi)存在1比匯編語言編寫的程序。這些編程語言允許更大，更復雜的方案，以獲得更快的發(fā)展。如果一個典型的機器語言指令可能會讀取10010 1100 1011，平均添加的內(nèi)容存儲到存儲寄存器A的內(nèi)容登記乙 高級語言是利用人類語言的文字和語法相對復雜的報表集。雖然所有的可執(zhí)行程序，最終由計算機在機讀語言，他們不是在所有機器語言編程。在機器語言，指令被寫為1和0，稱為序列位，一臺計算機可以直接理解。高層次的語言例如C語言，C + +，PASCAL的，和FROTRAN。編程語言可以被歸類為低層次的語言或高級語言。如231。如機器語言，其他語言的目的是由一個計算機系統(tǒng)，甚至在某些研究一個具體應用的計算機的特定模型。舉例來說，如FORTRAN語言和COBOL的編程語言被寫入唯一的某些一般的規(guī)劃問題，F(xiàn)ORTRAN語言語言類型的科學應用，以及商業(yè)應用的COBOL語言。編程語言差別很大的復雜性和在其多功能性程度。然而，自然語言不適合計算機編程，因為他們是含糊不清，這意味著他們的詞匯和語法結構可以以多種方式來解釋。在設計即將完成之際，我的心情無法平靜，從開始進入課題到設計的順利完成，有多少可敬的師長、同學、朋友給了我無言的幫助，在這里請接受我誠摯的謝意!最后我還要感謝培養(yǎng)我長大含辛茹苦的父母，謝謝你們!參考文獻[1] 曹衍龍.

Similar to natural languages, such as English, programming languages have a vocabulary, grammar, and syntax. However, natural languages are not suited for programming puters because they are ambiguous, meaning that their vocabulary and grammatical structure may be interpreted in multiple ways. The languages used to program puters must have simple logical structures, and the rules for their grammar, spelling and punctuation must be precise.Programming languages vary greatly in their sophistication and in their degree of versatility. Some programming languages are written to address a particular kind of puting problem or for use on a particular model of puter system. For instance, programming languages such as FORTRAN and COBOL were written to sole certain general types of programming problems —FORTRAN for scientific applications, and COBOL for business applications. Although these languages were designed to address specific categories of puter problems, they are highly portable, meaning that they may be used to program many types of puters. Other languages, such as machine languages, are designed to be used by one specific model of puter system, or even by one specific puter in certain research applications. The most monly used programming languages are highly portable and can be used to effectively solve diverse types of puting problems. Languages like C, PASCAL, and BASIC fall into this category.Programming languages can be classified as either lowlevel languages or highlevel languages. Lowlevel programming languages, or machine languages, are the most basic type of programming languages and can be understood directly by a puter. Highlevel languages are programming languages that must first be translated into a machine language before they can be understood and processed by a puter. Examples of highlevel languages are C, C++, PASCAL, and FROTRAN. Assembly languages are intermediate languages that are very close to machine languages and do not have the level of linguistic sophistication exhibited by other highlevel languages, but must still be translated into machine language. LanguagesIn machine languages, instructions are written as sequences of 1s and 0s, called bits, that a puter can understand directly. An instruction in machine language generally tells the puter four things: (1) where to find one or two numbers or simple pieces of data in the main puter memory (Random Access Memory, or RAM), (2) a simple operation to perform, such as adding the two number together, (3) where in the main memory to put the result of this simple operation, and (4) where to find the next instruction to perform. While all executable programs are eventually read by the puter in machine language, they are not all programmed in machine language. It is extremely difficult to program directly in machine language because the instructions are sequences of 1s and 0s. A typical instruction in a machine language might read 10010 1100 1011 and mean add the contents of storage register A to the contents of storage register B.2 .HighLevel LanguagesHighLevel languages are relatively sophisticated sets of statements utilizing words and syntax from human language. They are more similar to normal human language than assembly or machine languages and are therefore easier to use for writing plicated programs. These programming languages allow larger and more plicated programs to be developed faster. However, highlever languages must be translated into machine language by another program called a piler before a puter can understand them. For this reason, programs written in a highlevel language may take longer to execute and use up more memory than programs
