错误代码

class school{
public:string name;static string address;
public:static string getAddress(){return address;}
};school::address = "南京路";

原因

school::address = “南京路”;前面未加类型，导致编译错误

解决

class school{
public:string name;static string address;
public:static string getAddress(){return address;}
};string school::address = "南京路";
