    } 
    else

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


} 

Answer 1

你有什麼只是簡單地把箭頭對方，這就是爲什麼數據不會去到 empfile對象

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