基于以太坊的智能合约开发教程Solidity 多重继承

pragma solidity ^0.4.0;

contract testOne {
    uint money =100;
    
    uint height =188;
    
    function dance()public pure returns(string){
        return "one dance";
    }
}

contract testTwo {
    uint money =200;
    
    uint height = 165;
    
     function dance()public pure returns(string){
        return "two dance";
    }
}


    // 当合约多重继承时，并且有重复的属性需要继承的时候，以继承的最后一个合约里的属性为主
contract test is testOne,testTwo{
    
    uint height = 177;
    
    //  当合约本身也有与继承合约相同的属性时，使用的是合约本身的属性 
    
    function getMoney()public view returns(uint){
        return money;   // 200
    }
    function getHeight()public view returns(uint){
        return height;   // 177
    }
    function getDance()public pure returns(string){
        return dance();  // "two dance"
    }
    
}
