waiting time-计算等待时间之后的时刻，按24小时制计算，允许重复计算：
//waiting time
#include<iostream>
using namespace std;
void get_time(int& hours,int& minutes);
void convert_time(int& currenthours,int& currentminutes,int& waithours,int& waitminutes);
//void show_time();
int main()
{
int currenthours,currentminutes;
int waithours,waitminutes;
char ans;
do{
cout<<"Current time,";
get_time(currenthours,currentminutes);
cout<<"Wait time,";
get_time(waithours,waitminutes);
convert_time(currenthours,currentminutes,waithours,waitminutes);
cout<<"Do you want again?";
cin>>ans;
}while(‘y‘ == ans || ‘Y‘ == ans);
return 0;
}
void get_time(int& hours,int& minutes)
{
char b;
cout<<"Enter the 24 hours time like 11:11 :\n";
cin>>hours>>b>>minutes;
}
void convert_time(int& currenthours,int& currentminutes,int& waithours,int& waitminutes)
{
int hours,minutes;
if(currenthours + waithours < 24)
{
hours = currenthours+waithours;
if(currentminutes + waitminutes < 60)
minutes = currentminutes + waitminutes;
else
{
hours += 1;
minutes =(currentminutes + waitminutes) - 60;
}
}
else
{
hours = (currenthours+waithours) - 24 + currenthours;
if(currentminutes + waitminutes < 60)
minutes = currentminutes + waitminutes;
else
{
hours += 1;
minutes =(currentminutes + waitminutes) - 60;
}
}
cout<<"After the waiting time,the time is "<<hours<<":"<<minutes<<endl;
return;
}
结果：
Current time,Enter the 24 hours time like 11:11 : 12:30 Wait time,Enter the 24 hours time like 11:11 : 15:40 After the waiting time,the time is 16:10 Do you want again?y Current time,Enter the 24 hours time like 11:11 : 8:30 Wait time,Enter the 24 hours time like 11:11 : 15:10 After the waiting time,the time is 23:40 Do you want again?
