1. 定义一个抽象学生类CStudent,它具有公有成员函数Average(),该函数用于计算学生的平均分,函数为虚函数;定义一个文科学生类CStudentLiberalArts,它是类CStudent的派生类,并以公有方式派生,它具有的成员有:
1) 保存英语、政治、数学、地理和历史、美术成绩的整形成员变量;
2) 设置上述变量的公有成员函数;
3) 输出上述变量的公有成员函数;
4) 公有的成员函数Average()用于计算学生的平均分;
定义一个理科学生类CStudentScience,它是类CStudent的派生类,并以公有方式派生,它具有的成员为:
1) 保存英语、物理、数学、化学和计算机、程序设计成绩的整形成员变量;
2) 设置上述变量的公有成员函数;
3) 输出上述变量的公有成员函数;
4) 公有的成员函数Average()用于计算学生的平均分;
编写主函数,并测试以下内容:
1) 定义一个CStudent的指针数组pStu,数组长度为4;
2) 动态创建2个文科学生的对象,地址存于pStu数组的0-1个元素内;
3) 动态创建2个理科学生的对象,地址存于pStu数组的2-3个元素内;
4) 利用while循环调用数组里每个元素的计算平均成绩操作;
释放动态分配的空间,确保必要的析构函数能被调用。

time_delay
控制理论算法在采用状态反馈对目标进行控制时,往往忽略了时滞的存在。时滞往往存在于真实的系统中,而忽略时滞所设计的控制器在复杂的系统中可能会失效。本算法基于李雅普诺夫稳定性理论,以LMI的方式给出时滞系统的稳定性分析判据。(Time delay is widely existed in many engineering contrl systems whiile in many contrl theory and algothms time delay is ignored. This algorithm is given to analysis the stability of close- loop feedback time delay systems. And classical examples are given to demanstrate the effectiveness of this method.)
