Erasing the content of an array struct. 3 questions

**Xoled** · 09-14-2010

So, i'm trying to simulate a program that organizes clients on a plane.

I made a menu, and i have to make 4 options;

1. Add passengers to a seat [Check]
2. Check reservations [Check]
3. Erasing reservations
4. Check available spaces.

This is my struct;

Code:

struct Person { 
   char Name[65]; 
   char ID[20];
   char gender[10]; 
   int age; 
}Vip[4][3],Smokers[9][5],Non[9][5];

Then i have a switch to select the options, i already made 1 and 2 completely, and thank god they are working, it took me all afternoon

Could you help me out with the two other options?

How can i erase the content of my seats?

And how do i make it so that it can "realize" that the seat is already taken

How can i make it count the available seats?

Your data organization looks sloppy. I suggest you rework out your data structure. Using classes would be nice (since this is a C++ application), but you can still improve your organization with just using structures. Here's an example:

Code:

enum Gender
{
    MALE,
    FEMALE
};

struct Person {
    std::string name; 
    std::string id;
    Gender gender;
    int age; 
};

struct Seat { 
    Person person;
    bool available;
};

struct Plane {
    Seat vip_seats[4][3];
    Seat smoker_seats[9][5];
    Seat nonsmoker_seats[9][5];
};

I think with these type of data structures, you can easily answer the questions you have.

thanks for your reply bithub, well, it really got me to want to learn to use those but..

i really wouldn't know how to link them and treat them lol, i'm just a noob, the teacher knows we cant do this well cause we just started the subject but he's testing us and only a few will pass...

I'm still trying to figure out a method to erase the structures ("removing a reservation") with my current setup

You can't "erase" an index from an array. That's why I added the "available" member so that you can check if a seat is taken or not.

Oh i see, i think i figured out a way that will work to check the availabilty.

I still HAVE to add an option that wipes the reservations clean though... how would i do that?

Thanks for the support bithub

If you set the seat to "available", wouldn't that be the equivalent of deleting the reservation?

**Xoled** · 09-14-2010

Oh okay, that way i would make it re-writable! [i understand what i said] hahah

that's a great idea

BUT!!!!

the teacher could still check the struct and it would still have the data of the passenger

Uh right. But the task is to create a program to can add and remove reservations, no? Then the user won't "browse" the code, so for all intents and purposes, it works fine.
