与金钱支付功能有关的稳健性申报错误

Question

我刚开始踏实

我的目标是使这些代码在remix编译器中工作。

该代码是一个" for“函数，它意味着在死者= true (代码用于继承契约)时触发，但它在最后两行代码的”钱包“部分有问题。

我试着在这里和其他地方寻找解决方案(比如Solidity/Remix文档)，但仍然在努力解决这个特殊的问题。

我尝试删除"i"，添加";“，并在钱包的开头添加下划线(如"_wallets")。

有人告诉我，我已经申报了钱包，但我不知道你是怎么做到的。

这是完整的继承契约代码：

// SPDX-License-Identifier: GPL-3.0
//import solidity 
pragma solidity ^0.8.0;

contract Inheritance { 
    address owner;
    bool deceased;
    uint money;
    

    constructor () public payable {
        owner = msg.sender;
        money = msg.value;
        deceased = false;

}

modifier oneOwner {
    require (msg.sender == owner);
    _;
}

modifier isDeceased {
    require (deceased == true);
    _;

address [0xa1F9019E4F941071cAabCbb3fBc6314c06BeD18f] wallets;

mapping (address => uint) inheritance;
}

function setup(address _wallet, uint _inheritance) public oneOwner {
    _wallet.push(_wallet);
    Inheritance [_wallet] = _inheritance; 
}

function moneyPaid() private isDeceased {
    for (uint i=0; i< wallets.length; i++) {
        wallets[i].transfer(Inheritance[wallets][i]);
    }
}

function died() public oneOwner { 
    deceased = true; 
    moneyPaid();
}
}

以下是我所犯的错误：

DeclarationError: Undeclared identifier.
--> Inheritance contract 1.1.sol:38:20:
|
38 | for (uint i=0; i< wallets.length; i++) {
|                      ^^^^^^^




DeclarationError: Undeclared identifier.
--> Inheritance contract 1.1.sol:39:3:
|
39 | wallets;[i].transfer(Inheritance[wallets][i]);
|    ^^^^^^^

Answer 1

您的存储变量钱包在修饰符中。必须在修饰符之外声明状态变量。

 modifier isDeceased {
    require (deceased == true);
    _;
}

address [0xa1F9019E4F941071cAabCbb3fBc6314c06BeD18f] wallets;
mapping (address => uint) inheritance;

// }   --> not here
