Seven imported each headed for the median rank : 1. Keyboarding median and seven each, every few between certain distance from the two. Output for sorting data 2. Achieving 10 Adder, for example : 13 6 = 19 1. Augend augend have with the keyboard and display 2. Operational output structure of three. keyboarding an arbitrary character, and then output the characters, two empty grid later revealed that the characters in the ASCII one. keyboard and display 2.

编写出程序，在键盘上输入某人的月收入（允许达双字长），按照下列个人所得税的办法，计算并输出他应交纳的个人所得税税额。 个人所得税计算方法如下： 个人所得税实行累进税率，计算办法是用全月应纳税所得税分为几个级别，分别乘以累进税率，几个级别税额的总和就是该月应纳个人所得税额。全月应纳税所得额是用全月收入总额减去免税额（税法规定为８００元，广州市规定为１２６０元），个人所得税的税率分为９个级数（见下表）。 举例说明：杨某月收入为５５０００元，他的个人所得税应该这样计算： 应纳税所得额：５５０００－１２６０＝５３７４０元，共分为６个级别。 １级（５００元之内的部分）：５００*５%＝１５０ ２级（５００到２０００元之间的部分）：１５００*１０%＝４５０ ３级（２０００到５０００之间的部分）：３０００*１５%＝４５０ ４级（５０００到２００００之间的部分）：１５０００*２０%＝３０００ ５级（２００００到４００００之间的部分）：２００００*２５%＝５０００ ６级（４００００到６００００之间的部分）：１３７４０*３０%＝４１２２ 以此类推，杨某应缴个人所得税为１２７４７元。 -preparation procedures, the keyboard input of a persons monthly income (allowing double size), according to the following personal income tax, and calculation of the output he should pay the personal income tax allowance. Personal income tax calculations are as follows : a progressive personal income tax rate, the calculation method is used on all taxable income is divided into several levels, respectively, multiplied by the progressive tax rate several levels for the sum is taxed on the amount of personal income tax. Examples : Yang, on revenue of 55,000 yuan, his personal income tax should be calculated this way : taxable income for the :55000-1260 = 53,740 yuan, is divided into six levels. A (500 million within the portion) : 500 * 5% = 150 2 (500 to 2,000 yuan between the part) : 下载

纵观市场上的安全产品，从网络防火墙到各种网络加密、个人数字签证以及早期硬盘锁，均未能对个人计算机本身进行实质性的保护。这些安全机制大都基于这样一种原理：利用一个软件，输入一个特定的密码，经过验证后即可获得合法身份，从而实现各种操作，如购物、收发公文、浏览甚至修改机密数据。众所周知，这种基于纯密码的机制是很脆弱的，所以，许多关键行业和部门都采用了软、硬结合的方式，如设立各种Smart卡认证机制。在银行工作的职工，每人都有一张代表自己电子身份的IC卡，每天上班，必须先刷卡才能进入银行的业务系统。这种机制的安全性大大提高了，但对于个人或普通企业用计算机，这种机制成本太高。本文从BIOS工作原理出发，提出一种安全性高、全新的计算机安全保护机制。 -Taking a panoramic view on the market safe products, from network firewall to various networks encryption, visa and personal digital locks early drives have failed to personal computer itself substantive protection. Most of these security mechanisms based on a principle : the use of a software, input a specific password, once validated receive legal status, thereby realizing a variety of actions, such as shopping, send correspondence, View or even confidential data. As we all know, such a pure password mechanism is very fragile, so many key industries and departments have adopted a soft, a combination of hardware, such as the establishment of the Smart Card authentication mechanism. The bank workers, everybody will have a representative of their electronic identity IC card to work everyday 下载

PL／0语言的文法规则 说明 (1)对原PL／0编译程序作了如下修改： 1’增加了输入文件ff和fi,输出文件fw2。 2’增加了保留字read和write，使保留字个数增至13。 3’关系运算符中的>=、<=和<>改为在过程getsym中说明。 4’在过程interpret中增加了读和写操作。 (2)预先建立PL／0语言源程序文件ff和其所需要的数据文件fi(文件名预先确定)。 (3)运行时在键盘上根据提示信息键入输出文件fw2的文件名(自行随时确定)。 -PL / 0 language grammar rules (1) the original PL / 0 compiler was amended as follows : 1 increase in the importation and fi ff paper, the output document fw2. 2 a reserved word read and write, make reservations number to 13 characters. 3 relations Operators of gt; =, Lt; = And lt; Gt; Getsym changed in the process described. 4 in the process interpret added to the read and write operations. (2) pre-establish PL / 0 ff language source files and the data they need fi document (document were pre-determined). (3) running at the keyboard on the basis of a message typing output files fw2 document (identify themselves at any time). 下载
