else 里面再开多一个if

            {
                  cost=minutes*.25;
            }

我写了一个，不过我没有test过的，你试一下看能用吗

#include<iostream>
using namespace std;

int main()
{
int startTime,endTime,weekday,weekend,hrs,min,minutes;
double cost;
char first, second, choice;

do
{
do
{
cout<<"When did the call start?\n";
            cout<<"Please enter the time in 24-hour notation.\n";
            cin>>startTime;
            cout<<"How long did the call last?\n";
            cin>>minutes;
            cout<<"Please enter the first two letters of the day of the call.\n";
            cin>>first>>second;
} while ((((first!='M')||(first!='m'))&&((second!='O')||(second!='o'))) || (((first!='T')||(first!='t'))&&((second!='U')||(second!='u'))) || (((first!='W')||(first!='w'))&&((second!='E')||(second!='e'))) || (((first!='T')||(first!='t'))&&((second!='H')||(second!='h'))) || (((first!='F')||(first!='f'))&&((second!='R')||(second!='r'))) || (((first!='S')||(first!='s'))&&((second!='A')||(second!='a'))) || (((first!='S')||(first!='s'))&&((second!='U')||(second!='u'))));

if ((first=='M')||(first=='m')||(first=='T')||(first=='t')||(first=='W')||(first=='w')||(first=='T')||(first=='t')||(first=='F')||(first=='f'))
{
if ((startTime>=800)&&(startTime<=1800))
                    cost=minutes*.40;
            else
                    cost=minutes*.25;
}
else
cost=minutes*0.15;

if ((first=='F')||(first=='f'))
{
hrs = minutes / 60 * 100;
min = minutes % 60;
endTime = starTime + hrs + min;

if (endTime > 2400)
{
weekday = ((2400 - startTime) / 100 * 60 ) * .25;
weekend = ((endTime - startTime) / 100 * 60)*.15;
cost = weekday + weekend;
}
}

if ((first=='S')||(first=='s')) && ((second=='U')||(second=='u'))
{
hrs = minutes / 60 * 100;
min = minutes % 60;
endTime = starTime + hrs + min;

if (endTime > 2400)
{
weekday = ((endTime - startTime) / 100 * 60 ) * .25;
weekend = ((2400 - startTime) / 100 * 60)*.15;
cost = weekday + weekend;
}
}

cout<<"The cost of the call is "<<cost<<".\n";
cout<<endl;
            cout<<"Do you want to rerun the program? Y or N\n";
            cin>>choice;
            cout<<endl;
}while ((choice=='Y')||(choice=='y'));

return 0;
}
