C++ 错误 "invalid constructor; your probably meant ' 帐户(常量帐户&)

Question

一直报错

invalid constructor; your probably meant Account (const Account&).

explicit Account (Account balance) {
   : accountBalance (balance);
}

我尝试将输入更改为 (Account balance) 并尝试使用 (int balance)。 int balance 给我一个错误

"expected primary-expression before ':' token.

完整代码

#include <iostream>
#include <string>
using namespace std;

class Account {
public:

    explicit Account (Account balance) {
       : accountBalance (balance);
    }

    void setAccountBalance (int balance) {
        accountBalance = balance;
    }

    int getAccountBalance () const {
        return accountBalance;
    }

    void displayBalance () const {
        std::cout << "Welcome to the Account. The balance is : $" << getAccountBalance() << std::endl;
    }

private:
    int accountBalance;
};

int main () {
    int startBalance = 0;
    Account myAccount1;

    cout << "Initial Dollar Amount is : " << myAccount1.getAccountBalance() << endl;
    cout << "Please enter new balance : " << endl;
    cin >> startBalance;

    myAccount1.setAccountBalance(startBalance);
    myAccount1.displayBalance();
}

Answer 1

替换

Account (Account balance) 

与

Account (int balance)
