你的提问不是很清楚,回答起来有点困难。构造函数初始化,在public下写一个名字与类名相同的函数,函数体为实现初始化孝或的语句。注意它没有返回值,也可以物芦在类外定义。对于time::time(inth){hour=h}这样的可罩慎带以写为time::time(int
h):hour(h){}。
Clock类class Clock
{
int hour
int minute
int seconde
Clock()
{
hour = 0
伍友此 minute = 0
seconde = 0
}
~Clock()
{
cout<<"调用析构函数成功"<<endl
}
public void setH(int h)
{
hour = h
}
public void setM(int m)
{
minute = m
}
public void setS(int s)
{
second = s
}
public void display()
{
String hh = ""
String mm = ""
String ss = ""
if(hour<10)hh = "0"+hour
else hh = ""+hour
if(minute<10)mm = "0"+minute
else mm = ""+minute
告岩 if(seconde<10)ss = "0"腔迅+seconde
else ss = ""+second
cout<<hh<<":"<<mm<<":"<<ss<<endl
}
}
Main类
#include<iostream>
using namespace std
int main()
{
Clock clock = new Clock()
clock.setH(5)
clock.display()
}
