C++课程设计 求大神帮忙写下构造函数和析构函数

1.网格世界类
网格中每个元素存放各种生物对象的指针或者为空。模拟过程中,我们需要移动生物,还有繁殖和饥饿(死亡),所以在网格类中,我们可以将一只生物放到网格中;可以读取网格中的某个指定位置的生物,获取它的指针,以便在每一个time step中对它进行处理(移动、繁殖和饥饿死亡)。在一个time step中,网格中每只生物都要处理一遍,先狮蚁,后蚂蚁。另外,应该有一个显示网格的成员函数。
2.有机生物类
生物要能够放到网格中,所以每一只生物都有相关的函数。可以是构造函数,即构造生物的时候,同时指明放到网格的哪一个位置上。
有Move函数,Breed函数,Starve函数(是否饿死)。这些函数在派生类中有派生类自己的实现。所以,在有机生物类中,这些函数应该是纯虚函数,有机生物类是一个抽象类。
网格世界类中,从某个网格位置读取生物并处理时,需要知道是哪一种类型的生物(是狮蚁还是蚂蚁),所以,有机生物类里应该考虑如何返回生物的类型。简单的办法是,用不同的常量来表示狮蚁和蚂蚁。例如,用整数1表示狮蚁,2表示蚂蚁。在有机生物类中定义纯虚函数GetType,返回生物的具体类型。
3.蚂蚁类
实现Move函数,Breed函数,Starve函数和GetType函数。
4.狮蚁类
实现Move函数,Breed函数,Starve函数和GetType函数。
(二)细化:
1.网格世界类:
(1)属性。数据结构:网格世界中如何存放蚂蚁或狮蚁对象?
20*20的网格,用一个20*20的二维数组来表示,数组元素是什么类型?
(2)方法。网格世界类应该有哪些成员函数?
构造函数:初始化网格。
析构函数:释放掉所有生物。
Set函数:指定x,y位置(二维数组的下标),以及一只生物的地址(指针),将这只生物存入网格中。
Get函数:获取网格中x,y坐标上的生物的地址(指针)。
OneStep函数:在一个time step中,网格中每只生物都要处理一遍,包括移动、繁殖和饥饿。首先,把网格中的每一只生物在本轮是否移动过的标记moved先都标记为假(为什么?);其次,移动,先狮蚁,后蚂蚁,同时把该生物的moved标记为真;再次,把饥饿的狮蚁消灭掉;最后,繁殖。
Display函数:显示函数,显示网格中的具体情况。每个网格,如果是空,显示”.”;如果是蚂蚁,显示”o”;如果是狮蚁,显示”x”。
2.有机生物类
(1)属性
要记录每只生物的一些基本属性:属于哪个网格对象,具体在哪个位置上(x,y坐标),本轮是否移动过。另外,为了记录是否到了繁殖时间,要有一个跟踪器,即记录上次繁殖之后,又经历了多少次time step。
(2)方法
构造函数:
带参数的构造函数:指定网格对象和x、y位置,把构造的生物放到网格中。
析构函数:
Move函数,Breed函数,Starve函数和GetType函数为纯虚函数。
3.蚂蚁类
(1)属性
不需要再添加属性。
(2)方法
构造函数:
带参数的构造函数:指定网格对象和x、y位置,把构造的蚂蚁放到网格中。
析构函数:
Move函数:随机选择一个方向,看是否能移动,否则保持在原位置。
Breed函数:繁殖跟踪器+1.如果是3的倍数,就需要繁殖,同时跟踪器清零。
Starve函数:本模拟中蚂蚁不会饿死,所以仅返回false值即可。
GetType函数:返回蚂蚁的类型标记。
4.狮蚁类
(1)属性
狮蚁会饿死,需要添加一个属性,跟踪记录狮蚁饥饿了多少次time step。
(2)方法
构造函数:
带参数的构造函数:指定网格对象和x、y位置,把构造的狮蚁放到网格中。
析构函数:
Move函数:若有相邻蚂蚁,移动到单元网格,吃掉蚂蚁;否则,随机选择一个方向,看是否能移动,不能移动则保持在原位置。
Breed函数:繁殖跟踪器+1,如果是8的倍数,就需要繁殖,同时跟踪器清零。
Starve函数:饥饿跟踪器+1,如果是3的倍数,则饥饿并死亡,从网格中拿掉该狮蚁,同时跟踪器清零。
GetType函数:返回狮蚁的类型标记。
四、其它
(一)所有涉及的常量定义为类型常量。如:
const int ANTBREED = 3; //蚂蚁的繁殖周期为3个time steps
const int DOODLEBREED = 8; //狮蚁的繁殖周期为8个time steps
初始化网格世界时,用的狮蚁只数和蚂蚁只数,分别为5只和100只,也定义为类型常量。如:
const int INITIALANTS = 100;
const int INITIALBUGS = 5;
