假设你需要指定范围内的随机数，传统的方法是使用ANSI C的函数random(),然后格式化结果以便结果是落在指定的范围内。但是，使用这个方法至少有两个缺点-suppose you need, within specified limits, random number, the traditional method is to use ANSI C function random (), then formatted results to the results fell within the scope specified. However, the use of this method at least two shortcomings

* 用改进的欧拉方法求解初值问题，其中一阶微分方程未y =f(x,y) * 初始条件为x=x[0]时,y＝y[0]. * 输入: f--函数f(x,y)的指针 * x--自变量离散值数组(其中x[0]为初始条件) * y--对应于自变量离散值的函数值数组(其中y[0]为初始条件) * h--计算步长 * n--步数 * 输出: x为说求解的自变量离散值数组 * y为所求解对应于自变量离散值的函数值数组 -* Improved Euler method to solve initial value problems, not an order differential equation y = f (x, y)* initial conditions for x = x [0], y = y [0].* Input : f-- function f (x, y)* x pointer-- from the array variable discrete values (x [0] for the initial conditions)* y-- corresponding to the variable discrete value of the function of the array (y [0] for the initial conditions)* h-- calculated step* n-- steps* output : Solving for x that the variable array* discrete values by solving y variables corresponding to the value of the discrete function arrays

毕业生就业问题是每个高校以及社会关注的焦点之一；学生如果能充分考虑各个方面的因素，综合评价后再确定自己的就业岗位的取向对其成功就业是有很大帮助的；学校有关部门如能掌握毕业生的就业岗位取向就能及时地调整工作重点并更好地指导和帮助学生就业。在本问题中，我们通过附件所给出的数据利用数学模型的思想与方法，重点对1995―2007年这13年的毕业生就业情况进行了较全面的统计与分析。-The employment problem of graduates of each college, as well as one of the focal points of social concern students if they can give full consideration to various factors, comprehensive evaluation and then determine their own jobs to their success-oriented employment is of great help schools departments, such as graduates to acquire jobs in a timely manner to adjust the orientation will be able to focus and to better guide and help students in employment. In this problem, we adopted the data given in the Annex to the use of mathematical models of thinking and methods, with emphasis on the 1995-2007 graduates of 13 years in the employment situation in a more comprehensive statistics and analysis.

在一个多道程序设计系统中，实现“作业调度”的模拟。模拟程序的要求如下： 1．输入： 作业流文件，其中存储的是一系列待执行的作业信息，每个作业包括五个数据项：作业号，优先级，进入输入井时间（用一个整数表示，如10：10表示为1010），作业估计运行时间（单位：分钟），内存需求量。各数据项用空格隔开。 2．输出： 按照作业调度次序输出每一个作业流文件：“作业号”、“进入内存时间”、“作业完成时间”、“周转时间”；每行输出一个作业的信息。 计算出平均周转时间并输出。 3．作业调度算法： 短作业优先（作业估计运行时间最短的作业首先被调度）。 4．处理要求： 在两道环境下有多个作业； 程序运行时，首先提示输入测试文件的文件名； 输入文件名后，程序将读入文件中的有关数据，并按照最短作业优先调度算法对作业进行调度，作业被调度运行后不再退出（忽略进程调度或者可以认为进程调度采用的是先来先服务调度算法）； 假设内存容量为100K，存储管理方案为可变分区方式，且不允许在内存中移动作业。 -in a multi-program design system, and achieving a "Dispatch" the simulation. The simulation procedure is as follows : 1. Input : Job Flow document, which is stored in a series of operations to be implemented information, including five each operating data : the operations, priority, time to enter the input shaft (with an integer, as expressed to 10:10 1010), is estimated to run time (unit : minutes), the memory demand. The data item separated by a space. 2. Output : In accordance with the scheduling order of output per work- a document : "
