函数继承分为
- 构造器继承
- 普通方法继承
子合约需要调用父合约的构造函数。
如果父合约构造函数有参数，那么子合约需要提供参数调用父合约。
两种调用，一个是在声明中直接赋值，一个是像修饰器一样，调用时再赋值。
pragma solidity ^0.4.18;
contract A{
constructor(uint a){}
}
contract B is A(5){
function hello() public{
}
}
pragma solidity ^0.4.18;
contract A{
constructor(uint a){}
}
contract B is A{
constructor(uint s) A(s + 1){}
}
上面传递给父合约的构造函数的参数可以进行修改。
