I can't figure out what I have wrong here. It always says invalid choice.

char menu ()
{
char userChoice;
cout<<"Surface Area Calculator";
cout<<"\n\nS) Sphere";
cout<<"\nC) Cone";
cout<<"\n\nQ) Quit";
cout<<"\n\nEnter your choice: ";
cin>>userChoice;
cout<<endl;
userChoice = toupper (userChoice);
while (userChoice != 'S' or userChoice != 'C' or userChoice != 'Q')
{
userChoice = toupper (userChoice);
cout<<userChoice<<" is an invalid choice. Try again: ";
cin>>userChoice;
}
return userChoice;
}

They should be and not or. Also, generally we use && for logical and and || for logical or instead of and/or.
