/* * Copyright (c) 2014,烟台大学计算机学院 * All rights reserved. * 文件名称：test.cpp * 作 者：刘畅 * 完成日期：2014 年 11 月 26 日 * 版 本 号：v1.0 * * 问题描写：某班不超过100名同学，用2维数组score[ ][4]保存同学们的高数、英语、C++成绩及总成绩(在此假定学生的学号为整形的连续值，用数组的行下标作学号)。在此基础上，完成相应的要求； * 输入描写：（1）输入学生人数、学生3科的成绩，（2）还要输入学生姓名； * 程序输出：输出各门课及总分的最高成绩、最低成绩、平均成绩和最高分数取得者。
