Private & public function problem

[blackshore]

Hello I'm learning cpp and I'm currently fiddeling with private and public functions.
I think I have missed something in my code.
Thanks for any advice

ERROR on line 43:

too few arguments to function call single argument 'x' was not specified

#include <QCoreApplication>
#include <string>
#include <iostream>

using namespace std;

class MilkshakeClass{

        private: // Milkshake Factory

            string MilkShakeName;



// ----------------------------------------

        public:    // Milkshake Distributor

        void setMilkshakeName (string x) {
                MilkShakeName = x;

}

        string getMilkshakeName(){
                return MilkShakeName;
}

};


// =====================================



int main(int argc, char *argv[]) // Milkshake shop
{
    QCoreApplication a(argc, argv);

    MilkshakeClass MilkshakeObjekt;
    cout << "Name your Milkshake \n";


    cin >> MilkshakeObjekt.setMilkshakeName();

    cout << MilkshakeObjekt.getMilkshakeName();

    return a.exec();
}

void setMilkshakeName (string x)
This function expects one parameter. A string.


How many have you passed when you tried to use the function?
MilkshakeObjekt.setMilkshakeName();
Zero. This makes no sense.

  cout << "Name your Milkshake \n";
  string userinput;
  cin >> userinput;
  MilkshakeObjekt.setMilkshakeName(userinput);
