solidity智能合约[35]-function-automatic

uint public num = 100;
自动生成的函数为:
  function num() external pure returns(uint){
      return 200;
  }

mapping(uint =>string) public map;
//自动生成的函数
function map(uint key) external view returns(string){
    return map[key];
}

mapping(uint=>mapping(uint=>uint)) public grademap;
//自动生成的函数
function grademap(uint key1,uint key2) external view returns(uint){
    return grademap[key1][key2];
}
