,急，关于c++这一句有什么问题？
cout<<"\t\t\t\t"<<setiosflag(sios::left)<<setw(17)<<"Tax"<<setprecision(2)<<tax<<endl<<endl;

打错了，请看这cout<<"\t\t\t\t"<<setiosflags(ios::left)<<setw(17)<<"Tax"<<setprecision(2)<<tax<<endl<<endl;

What is your problem?

Do you want the output to be like this:(suppose tax=0.053)

--------------------------------Tax--------------0.05

?

//Before Tax 32 blanks and after Tax 14 blanks.





I think you might not be able to get 0.05, right?

This is because setprecision() should be used together

with "showpoint" or "fixed".

You can try this:

cout << "\t\t\t\t" << setiosflags(ios:left) << setw(17)
<< "Tax" << setiosflags(ios:fixed) << setprecision(2)
<< tax << endl << endl;
