    else

    empfile >> nic >> ' ' >>firstName >> ' ' >> lastName >> ' ' >> dob >> ' ' >>pnum>> ' ' >>address >> ' ' >> salary>> endl; 
    empfile.close(); 


} 

Answer 1

你有什么只是简单地把箭头对方，这就是为什么数据不会去到 empfile对象

empfile << nic << ' ' <<firstName << ' '<< lastName << ' '<< dob << ' '<<pnum<<' '<<address <<' '<<salary<< endl; 
    empfile.close();
