區塊鏈學堂（24） Struct型別

例如定義乙個struct型別的person

struct person

pragma solidity 0.4.10;

contract demotypes9 
person public personlist;
}

step 1-2後，完整**如下：

pragma solidity 0.4.10;

/*演示一下結構，如何和陣列型別結合，一起使用；*/
contract demotypes9 
person public personlist;
function demotypes9() 
}

function addperson (string _name, uint _***y, uint _age, string _mobile)

function addperson2 (string _name, uint _***y, uint _age, string _mobile) );

}

browser-solidity的執**況如下

pragma solidity 0.4.10;

/*演示一下結構，如何和陣列型別結合，一起使用；*/
contract demotypes9 
person public personlist;
function demotypes9() 
function addperson (string _name, uint _***y, uint _age, string _mobile) 
function addperson2 (string _name, uint _***y, uint _age, string _mobile) );}}
