problem ：A 第一个类
#include <iostream>
#include <iomanip>
#include <cstring>
#include <cmath>
using namespace std;
class Thing
{
private:
string name;
public:
Thing(){}
Thing(string n):name(n) {cout << "" << name << endl;}
~Thing(){ cout << "Destroy a thing" << " " << name << endl;}
};
int main()
{
Thing A("Car");
string str;
cin>>str;
Thing B(str);
return 0;
}
problem b：建造一间教室
description：
一间教室包括很多物品。这里只考虑灯（Light）和椅子（Chair）。定义Light类，只有一个int类型的参数，表示灯的瓦数；定义Chair类，只有一个字符串类型的参数，表示椅子的颜色。定义ClassRoom类，包括四个属性：两个int类型的属性，分别为灯的个数和椅子的个数。一个Light类的对象和一个Chair类的对象，分别为教室中灯的种类和椅子的种类。
input：
输入有6行，第1行是一个正整数，表示灯的瓦数。第2行是一个不含空白符的字符串，表示椅子的颜色。第3、4行表示教室中灯的个数和椅子的数量。第5行是一个正整数，表示教室中灯的瓦数，第6行是一个不含空白符的字符串，表示教室中椅子的颜色。
sample input：
20
blue
16
100
25
red
sample output：
代码示例：
1 #include <iostream>
2 #include <iomanip>
3 #include <cstring>
4 #include <cmath>
5 using namespace std;
6 class Light
7 {
8 private:
9 int w;
10 public:
11 Light(){ }
12 Light(int ww):w(ww){ cout << "A " << w << "w light is created." << endl; }
13 ~Light(){ cout << "A " << w << "w light is erased." << endl;}
14 int getw() const { return w; }
15 };
16 class Chair
17 {
18 private:
19 string cl;
20 public:
21 Chair(){ }
22 Chair(string c):cl(c){ cout << "A " << cl << " chair is created." << endl; }
23 ~Chair(){ cout << "A " << cl << " chair is created." << endl;}
24 string getcl() const { return cl; }
25 };

27 class ClassRoom
28 {
29 private:
30 int lnum, cnum;
31 Light lig;
32 Chair cha;
33 public:
34 ClassRoom(){ }
35 ClassRoom(int ln,int cn,int w,string c ): lig(w), cha(c),lnum(ln), cnum(cn)
36 {
37 cout << "A classroom having " << lnum << " lights and " << cnum << " chairs is created." << endl;
38 }
39 ~ClassRoom(){ cout << "A classroom having " << lnum << " lights and " << cnum << " chairs is erased." << endl;}
40 };
41
42 int main()
43 {
44 int nl, nc;
45 int w;
46 string color;
47 cin>>w>>color;
48 Light light(w);
49 Chair chair(color);
50 cin>>nl>>nc;
51 cin>>w>>color;
52 ClassRoom room(nl, nc, w, color);
53 return 0;
54 }
problem c: 是否回文数？
description ：
定义Data类，有一个int类型的属性。定义其构造函数、setValue函数和isPalindrome函数，其中setValue函数用于设置属性值，isPalindrome用于判断该属性值是否为回文数。判断回文数时，不考虑数的符号。
输入：
若干个int类型范围内的整数
输出：
每个输入对应一行输出，如果对应的输入是回文数，则输出Yes，否则输出No。
代码演绎：
1 #include <iostream>
2 #include <iomanip>
3 #include <cstring>
4 #include <cmath>
5 using namespace std;
6 class Light
7 {
8 private:
9 int w;
10 public:
11 Light(){ }
12 Light(int ww):w(ww){ cout << "A " << w << "w light is created." << endl; }
13 ~Light(){ cout << "A " << w << "w light is erased." << endl;}
14 int getw() const { return w; }
15 };
16 class Chair
17 {
18 private:
19 string cl;
20 public:
21 Chair(){ }
22 Chair(string c):cl(c){ cout << "A " << cl << " chair is created." << endl; }
23 ~Chair(){ cout << "A " << cl << " chair is created." << endl;}
24 string getcl() const { return cl; }
25 };

27 class ClassRoom
28 {
29 private:
30 int lnum, cnum;
31 Light lig;
32 Chair cha;
33 public:
34 ClassRoom(){ }
35 ClassRoom(int ln,int cn,int w,string c ): lig(w), cha(c),lnum(ln), cnum(cn)
36 {
37 cout << "A classroom having " << lnum << " lights and " << cnum << " chairs is created." << endl;
38 }
39 ~ClassRoom(){ cout << "A classroom having " << lnum << " lights and " << cnum << " chairs is erased." << endl;}
40 };

42 int main()
43 {
44 int nl, nc;
45 int w;
46 string color;
47 cin>>w>>color;
48 Light light(w);
49 Chair chair(color);
50 cin>>nl>>nc;
51 cin>>w>>color;
52 ClassRoom room(nl, nc, w, color);
53 return 0;
