Without throwing it into a complier, VS doesn't use int main(). It uses int _tmain(int argc, _TCHAR* argv[]) EDIT after throwing it into VC++: struct Travel::Hotel Hot_1; In your main function, you attempt to make a copy of a struct you defined as private to class Travel. You cannot do this.

Razor2.3 thank you for your answer.I am still new to programming......so i am failing to understand how to go about it.As for attempting to make a copy of a struct i defined as private to class Travel in the main function I got it.

Step 1: Change the main()'s definition as I said in my previous post. Step 2: Get rid of the line struct Travel::Hotel Hot_1; in your main function. You don't need it, and you never do anything with it. Step 3: Just below that line, strip the void off of the line below that. Step 4: Move the entire main function below the displayVoid() function. Step 4 Alt: Before the main function, add the following line: void displayMain();

thank you once again Razor2.3.Now the problem is that the program can't be executed.When i compile there are no errors.

Hi...the program is now executable.Now how do i enter and display information for different(several) hotels,resorts and clients? #include <iostream> #include <string> using namespace std; //class TRAVEL CONTROLS ALL FUNCTIONS class Travel { struct Hotel { string cityName; string hotelName; int hotelCode; int standardRoomNo; int standardRoomPrice; int deluxeRoomNo; int deluxeRoomPrice; }H; struct Resort { string cityName; int resortID; string resortName; int numberOfResorts; int resortPrice; }R; struct Booking { int reservationNum; string clientName; int contactTel; string email; char option; }B; public: void Hotelinput(); void Resortinput(); void Bookinginput(); void Display1(); void Display2(); void Display3(); } P; //********************************************************** // FUNCTION NAME : Hotel //********************************************************** void Travel::Hotelinput() { //DATA OF HOTEL cout<<"Enter Hotel Information:"; cout<<"Enter City Name:"; cin>>(H.cityName); cout<<"Hotel Name:"; cin>>(H.hotelName); cout<<"Hotel Code:"; cin>>(H.hotelCode); cout<<"Standard Room Number:"; cin>>(H.standardRoomNo); cout<<"Standard Room Price:"; cin>>(H.standardRoomPrice); cout<<"Deluxe Room Number:"; cin>>(H.deluxeRoomNo); cout<<"Deluxe Room Price:"; cin>>(H.deluxeRoomPrice); } void Travel::Resortinput() //DATA OFRESORT { cout<<"Enter City Name:"; cin>>(R.cityName); cout<<"Enter Resort ID:"; cin>>(R.resortID); cout<<"Enter Resort Name:"; cin>>(R.resortName); cout<<"Number Of Resorts:"; cin>>(R.numberOfResorts); cout<<"Enter Resort Price:"; cin>>(R.resortPrice); } void Travel::Bookinginput() //BOOKING DATA { cout<<"Enter Reservation Number:"; cin>>(B.reservationNum); cout<<"Enter Client Name:"; cin>>(B.clientName); cout<<"Enter Contact Tel.:"; cin>>(B.contactTel); cout<<"Enter E-mail:"; cin>>(B.email); cout<<"Enter Catergory(H for Hotel,R forResort):"; cin>>(B.option); } void Travel::Display1() { cout<<"Hotel information:"; cout<<"City Name:"<<H.cityName<<endl; cout<<"Hotel Name:"<<H.hotelName<<endl; cout<<"Hotel Code:"<<H.hotelCode<<endl; cout<<"Standard Room Number:"<<H.standardRoomNo<<endl; cout<<"Standard Room Price:"<<H.standardRoomPrice<<endl; cout<<" Deluxe Room Number:"<<H.deluxeRoomNo<<endl; cout<<"Deluxe Room Price:"<<H.deluxeRoomPrice<<endl; } void Travel::Display2() { cout<<"Resort information:"<<endl; cout<<"City Name:"<<R.cityName<<endl; cout<<"Resort Name:"<<R.resortName<<endl; cout<<"Resort ID:"<<R.resortID<<endl; cout<<"Resort Price:"<<R.resortPrice<<endl; } void Travel::Display3() { cout<<"Reservation Number:"<<B.reservationNum<<endl; cout<<"Client Name:"<<B.clientName<<endl; cout<<"Contact Tel.:"<<B.contactTel<<endl; cout<<"E-mail:"<<B.email<<endl; cout<<"Catergory:"<<B.option<<endl; } void displayMain(); int main() { displayMain(); return 0; } void displayMain() { {int selection; do { cout<<"**********MAIN**********"<<endl; cout<<"1.)

You need to either: A: Wrap your menu and your select case in a loop B: Have your displayMain() return the value of your selection, and place the loop in your main() function.
