cout << "-------------------------------------" << endl; cout << "     florida state university" << endl; cout << "     ticket information dept." << endl; cout << "-------------------------------------" << endl; cout <<""<< endl; cout <<""<< endl; cout << "please, enter name" << endl; cin >> name; cout << "how many florida state university credits have completed?" << endl; cin >> credits;  if (credits <0) {     cout<< "bad data recieved." << endl; } else {      if (credits <=30)     {         ticketamt=2;         cout <<name << ", eligible "<< ticketamt<< " tickets." << endl;     }     else if (credits <=60)     {         ticketamt=4;         cout <<name << ", eligible "<< ticketamt<< " tickets." << endl;     }     else if (credits <=90)     {         ticketamt=6;         cout <<name << ", eligible "<< ticketamt<< " tickets." << endl;     }     else      {         ticketamt=8;         cout <<name << ", eligible "<< ticketamt<< " tickets." << endl;     }      cout << "are florida resident? enter (y)es or (n)o" << endl;     cin >> resident;     if (resident !='y'||resident !='y'||resident !='n'||resident !='n')     {         if (resident=='y'||resident=='y')         {             tixprice=75;         }         else if (resident=='n'||resident=='n')         {             tixprice=95;         }          cout << "each ticket costs $" <<tixprice<< endl;         cout << "how many want?" << endl;         cin >> quantity;          if (quantity >ticketamt||quantity <0)         {         cout << "bad data -> number of tickets desired not in range" << endl;         }         else         {         totalprice = tixprice * quantity;         }     }     else     {         cout << "bad data recieved" << endl;     }  }

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
