help with calling this setter

void set_owner(string new_owner){owner = new_owner;}

can someone tell me how to call this setter from main?? i wrote this, and i believe i wrote it correctly, but cannot call it...

im trying to access owner from main, owner is a private member of a class....

any help would be great, im stumped

The set_owner needs to be a member function of that class
And you need to indicate when you call it which class object you're going to be using

myclass myobj;
myobj.set_owner( "me" );
