这是传入二进制文件的show1函数和读取信息的show2函数，希望能得到大佬的帮助
void show1() {
//获取初始化信息
cout << "请输入账号：";
string acNumber;
cin >> acNumber;
cout << "请输入用户名：";
string name;
cin >> name;

double sumOfMonney;
cin >> sumOfMonney;
//cout << "请设置账户密码：";
string p;
p = getPassword();
//产生账户

//打开二进制文件存储账户
string fname = "storeInfo";
fstream fs(fname, ios::binary | ios::out);
