When iam trying to make a class with an attribute string, it work like this: string name = " "; not like that: string name; why?
#include <iostream> #include <string> using namespace std; class myClass { public: string name; //doesnt work for me like this. }; int main() { myClass myObj; myObj.name = "SoloLearn"; cout << myObj.name; return 0; }

I'm guessing your getting a null reference error....
If so it is because you cannot use something that is nothing (i.e. null)
The compiler needs it to be something.
"" is giving it a default of empty string which is something.
