第一个C++例子 

 1 #include <iostream>
 2 using namespace std;

 4 class Time
 5 {
 6 private:
 7     int hour;
 8     int minute;
 9     int second;
10 public:
11     //Time() //无参够创函数
12     //{
13     //    hour = 0; minute = 0; second = 0;
14     //}
15     //Time(int h, int m, int s) //带参构造函数
16     //{
17     //    hour = h; minute = m; second = s;
18     //}
19     Time(int h = 0, int m = 0, int s = 0) : hour(h), minute(m), second(s){} //带参数初始化表的构造函数
20     void Set(int h, int m, int s);
21     void Show();
22 };
23 
24 void Time::Set(int h, int m, int s)
25 {
26     hour = h; minute = m; second = s;
27 }
28 void Time::Show()
29 {
30     cout << hour << ":" << minute << ":" << second << endl;
31 }
32 
33 int main()
34 {
35     Time t1;
36     t1.Show();
37     t1.Set(6, 18, 16);
38     t1.Show();
39 
40     Time t2(12, 11, 10);
41     t2.Show();
42 
43     return 0;
44 }
