solc编译错误

Question

当我编译一个简单的代码时，我会在代码下面捕捉到"索尔克预期的主表达式“。

if (highestBidder != 0) {
          highestBidder.send((highestBid),
        }

.i知道有一些错误的代码格式，但我不知道如何修改它？

pragma solidity ^0.4.4;
contract SimpleAuction {

  address public beneficiary;
  uint public auctionStart;
  uint public biddingTime;


  address public highestBidder;

  uint public highestBid;


  bool ended;


  event HighestBidIncreased(address bidder, uint amount);

  event AuctionEnded(address winner, uint amount);


  function SimpleAuction(uint _biddingTime, address _beneficiary) {
    beneficiary = _beneficiary;
    auctionStart = now;
    biddingTime = _biddingTime;
  }


  function bid() {

    require(condition, message); (now > auctionStart + biddingTime) ;


    require(condition, message); (msg.value <= highestBid);



    if (highestBidder != 0) {
      highestBidder.send((highestBid),
    }
    highestBidder = msg.sender;
    highestBid = msg.value;
    HighestBidIncreased(msg.sender, msg.value);
  }

  function auctionEnd() {
    require(condition, message); (now <= auctionStart + biddingTime);
    require(condition, message); (ended);
    AuctionEnded(highestBidder, highestBid);

    beneficiary.send(this.balance);
    ended = true;
  }

  function () {
    throw;
  }
}

Answer 1

将send((highestBid),改为send(highestBid);！

请记住，Solidity并不是一种语言，您只需在表达式中添加一些随机字符，并希望它能够编译(与任何其他语言一样，除了解释语言之外，您可以用“run”替换“编译”一词)。
