C++ifstream 文件写入的问题

void Cadmin_info::output(){
std::ofstream file;
file.open("班次信息.txt",ios_base::app);

file<<number<<" "<<_origin<<" "<<_destination<<" "<<h_star<<" "<<m_star<<" "<<h_arrive<<" "<<m_arrive<<" "<< numofstand<<" "<<priceofstand<<" "<<numofhardseat<<" "<<priceofhardseat<<" "<<numofhardsleeper<<" "<< priceofhardsleeper<<" "<<numofsoftsleeper<<" "<<priceofsoftsleeper<<endl;
file.close();
}

void Cadmin_info::input(){
ifstream file;
file.open("班次信息.txt");
char a[100];
file.getline(a,' ');
}

我的目的是：向从TXT中把number _origin _destination 等这些变量一个一个取出来，然后赋值给别的变量。如a=number; 如何实现？ 是否应该用getline，或者别的方法呢？

Answer 1

file.open("班次信息.txt");

file>>number>>_destination>>h_star……

然后a=number
