用solidity编写汽车报价合约：
pragma solidity^0.4.22;
contract Car{
string brand;
uint price;
constructor(string initBrand，uint initPrice) public{
brand = initBrand;
price = initPrice;
function setBrand(string newBrand) view returns(string){
brand = newBrand;
}
function getBrand() public view returns(string){
return brand;
}
function setPrice(uint newPrice) view returns(uint){
price = newPrice;
}
}
继续加油！
