c++

I have problem with class object departure when I initialize it in the function I can output it with my overloaded operator but when I try to output departure outside the function it doesn't get recognised and I get error.

class PublicTransport: public Transport{ protected: Date departure(); string code; string from; string to; double priceOneSeat; bool firstClass=false;

public: PublicTransport(Date &x ,string a,string b,string c,double d,bool e){ Date departure(x);

cout<

cout<

void print(){

cout<

}
