Need some guidence please....

Hey guys I'm an absolute n00b so please be gentle. I'm having trouble with my project was hoping to see if I can get a push in the right direction.

I have to display information on a DVD that a user enters in, the last section where I have to have the Actor/Actress' name and their Character name added displayed. I'm not sure how to do this and my method that I have doesn't seem right.

"intructions"

The DVD class will have data members for the title of the movie, the length of the movie, and the year the movie was released. The class will have a vector which is used to store the name of the actors and actresses in the movie. Another vector will be used to maintain the character names that the actor/actress played in the movie. These two vectors must work in parallel, meaning the first actor/actress in the list must correspond to the first character in the other vector.

For the DVDs:

Movie Title
Length of Movie
Year Released
Actors/Actresses
Characters

Next I've got 3 options to Delete a DVD, Modify a DVD, and show all dvd's.... I don't even know where start, I'd appreciate a kick in the right direction..

Thanks guys, any help would be greatly appreciated!

The instructions are not 100% clear. I think you need to declare a vector<DVD> in your main function so you can add and display the dvds.

Here is the second part of the instructions that has got me confused, again being a n00b.... not sure where to begin.

The program will maintain a list of CD/DVDs. This list will be a vector of that class type (CD or DVD). The program must provide methods (functions) to add a CD/DVD, remove a CD/DVD and update a CD/DVD. There should also be a function that displays the entire list of CDs/DVDs. The output must be a table format, with heading.
