1. 创建合约
1.1. 创建未定义构造方法的合约
未定义构造方法的合约默认含一个无payable修饰的构造方法。
1.1.1. 部署成功情况
编写源码：
pragma solidity ^0.4.12;
contract DataStorage {
uint256 data;
function set(uint256 x) public {
data = x;
}
function get() public constant returns (uint256 retVal) {
return data;
}
}

代码执行过程分析：
构造方法是默认的。因为无payable修饰，所以转账额需要设置为0，才能部署成功。当转账额设置为0时，先将存储部分（黄色背景部分）暂存到内存，然后从内存再设置到执行结果的Return中。
1.1.2. 部署失败情况
返回空字节放入到执行结果的Return中，设置结果为REVERT，表示条件检验不过。
1.1.3. 乱写代码的情况
此时仍旧是按正常的处理流程，可能正常的退出，可能是REVERT，可能是异常（合约执行逻辑）。这时执行结果的Return没有被设置。
这是可以理解的，因为Solidity源码的逻辑本身不是执行平台能够控制的。
以太坊要求执行代码消耗Gas，所以作恶者也是要付出代价的，毕竟这个要占用网络的存储资源。
1.1.4. 代码为空的情况
是否允许为空，可以由业务决定。
1.2. 创建含无payable修改的含参构造方法的合约
源码：
pragma solidity ^0.4.12;
contract DataStorage {
uint256 data;
constructor(uint256 x) public {
data = x;
}
function set(uint256 x) public {
data = x;
}
function get() public constant returns (uint256 retVal) {
return data;
}
}

过程分析：
从字节码末尾加载参数并暂存到内存，然后又读出，存储到DB，Key是字段编号，从0开始。然后将部署部分设置到执行结果的Return中。
