Nested Structures - User Input

I am working on a program that requires a nested structure to store a departure date (day, month, year) and have declared it as such:-

Code:

struct departDate{
	int day;
	int month;
	int year;
	};

struct flightDetails{
	String flightNo;
	String departAirport;
	String arriveAirport;
	departDate date;
	String departTime;
	int seats;
	int reserved;
	double price;
	};

const int listSize = 30;  //number of records in array
int currentSize = 0;

I sort of understand the concept of nested structures and how to access structure members but in my program I don't set 'departure date' values I accept user input. I am unsure on how to store the user input. All references I have checked seem to initialise values for nested structures. I would like to ask the user only to enter one 'departure date' comprising of day, month and year as opposed to entering all three seperately. I thought the following code was correct:-

Code:

	cout<<"Enter departure date:";
	cin>>flightList[currentSize].date.day>>flightList
                [currentSize].date.month>>flightList 
                [currentSize].date.year;

but since I am having problems displaying my records on screen (fomatting of) I cannot check if this is correct.

Its one problem after another for us programming newbies!!

Any help would be gratefully appreciated

>I thought the following code was correct
Aside from being C++ and not C, the way you access the array of structures is correct. Let's break it down because the meat of your question is portable between C and C++.

>flightList[currentSize].date.day
Assuming flightList was declared as

Code:

flightDetails flightList[listSize];

The expression works as thus:

flightList is an array of flightDetails

flightList[currentSize] is a flightDetail object accessed by the subscript operator. flightList is an array, so subscripting is legal.

flightList[currentSize].date is a departDate object accessed by the member operator. flightList[currentSize] is a structure with a date member, so this is legal.

flightList[currentSize].date.day is an integer accessed by the member operator. date is a structure with a day member, so this is also legal.

>but since I am having problems displaying my records on screen (fomatting of)
That's your problem then. Start a new thread with that problem on the C++ forum and we'll help you out.
