更正建構子的程式碼
這個 StackExchange 問題幾乎回答了我的問題。但是我不知道如何準確地更正我的程式碼,以便以契約命名的函式被建構子替換。
該功能將如何具體糾正?
contract Fake_Smrt_Coin is EIC20{ uint256 constant private MAX_UINT256 = 2**256 - 1; mapping (address => uint256) public balances; mapping (address => mapping (address => uint256)) public allowed; string public name; uint8 public decimals; string public symbol; //I know this line needs improvement function Fake_Smrt_Coin ( uint256 _initialAmount, string _tokenName, uint8 _decimalUnits, string _tokenSymbol ) public { balances[msg.sender] = _initialAmount; totalSupply = _initialAmount; name = _tokenName; decimals = _decimalUnits; symbol = _tokenSymbol; } function transfer(address _to, uint256 _value) public returns (bool success) { require(balances[msg.sender] >= _value); balances[msg.sender] -= _value; balances[_to] += _value; emit Transfer(msg.sender, _to, _value); return true; }
更新的程式碼會是嗎?
constructor(){ string public name; uint8 public decimals; string public symbol; } function transfer(address _to, uint256 _value) public returns (bool success) { require(balances[msg.sender] >= _value); balances[msg.sender] -= _value; balances[_to] += _value; emit Transfer(msg.sender, _to, _value); return true; }
//I know this line needs improvement constructor ( uint256 _initialAmount, string _tokenName, uint8 _decimalUnits, string _tokenSymbol ) public { balances[msg.sender] = _initialAmount; totalSupply = _initialAmount; name = _tokenName; decimals = _decimalUnits; symbol = _tokenSymbol; }
希望能幫助到你。
只需
function Fake_Smrt_Coin
按程式碼字更改即可constructor
。希望這可以幫助。
