全部是一些基础的平时练习及作业题！都有源代码

#include <iostream.h>


class Times

private:
int hour; 
int minute;
int second;
public:

{hour=h;minute=m;second=s;}
Times operator ++();
void display();

};

void Times::display()
{ for(int i=1;i<20000;i++)
for(int j=1;j<20000;j++)
{ {} }
cout<<hour<<":"<<minute<<":"<<second<<endl;
}

{
if(++second>59)
{
second=0;
minute++;
if(minute>59)
{

}
}
return *this;
}

int main()
{
