表达式必须具有类类型

问题遇到的现象和发生背景

问题相关代码，请勿粘贴截图

#include<iostream>
using namespace std;
class Account
{
public:
    Account(char name[], long num, float amount);    //类的有参构造函数
    Account();                        //类的无参构造函数
    void deposit(float amount);     //往账户中存款
    int withdraw(float amount);     //从账户中取款（考虑透支情况）
    float getBalance();              //查询余额
private:
    char mName[20];                  //银行账户的户名
    long mSN;                         //本账户的帐号
    float mBalance;                   //本账户当前的余额
};
Account::Account(char name[], long num, float amount) {
    for (int i = 0; i < 20; i++) {
        name[i] = mName[i];
    }
    mSN = num;
    amount = mBalance;
}
void Account::deposit(float amount) {
    mBalance = mBalance + amount;
}
int Account::withdraw(float amount) {
    if (amount > mBalance) {
        cout << "您的余额不足" << endl;
        return 0;
    }
    else {
        mBalance = mBalance - amount;
    }
    return mBalance;
}
float Account::getBalance() {
    return mBalance;
}
void main() {
    int a;
    char name1[10]; long num1;
    float amount1 = 0;
    cout << "--------------------注册界面--------------------" << endl;
    cout << "用户名：" << endl;
    for (int i = 0; i < 10; i++) {
        cin >> name1[i];
    }
    cout << "账号：";
    cin >> num1;
    Account user1(char name1, long num1, float amount1);
    for (;;) {
        cout << "--------------------操作界面--------------------" << endl;
        cout << "1:存款;" << endl;
        cout << "2.取款;" << endl;
        cout << "3.查询余额" << endl;
        cout << "4.退出" << endl;
        cout << "------------------------------------------------" << endl;
        cin>>a;
        switch (a) {
        case(1):
            cout << "请输入您要存的金额" << endl;
            cin >> amount1;
            user1.deposit(amount1);
            system("pause");
            system("cls");
            continue;
        case(2):
            cout << "请输入你要取的金额" << endl;
            cin >> amount1;
            user1.withdraw(amount1);
            system("pause");
            system("cls");
            continue;
        case(3):
            user1.getBalance;
            system("pause");
            system("cls");
            continue;
        case(4):
            system("cls");
            break;
        }
    }
}

运行结果及报错内容

调用类里的函数时出现：表达式必须具有类类型，但它以及具有（。。）

我的解答思路和尝试过的方法

我想要达到的结果
