Displaying an array of classes

LiBRiUMz (33)
Hello!

Does anyone know how to go about displaying a class into an array? For example, I mad a class, and want to print it out as an array of maybe 10. I've looked online, and the examples are not very clear.

Thank you

It would be the same as creating an array of any other type then printing that.

foo arr[10] = {/* Fill in the contents here */};
for (int i = 0; i < 10; i++)
     cout << arr[i];


Have you defined output, constructors, and assignment for your class?

For example, this is the class that I have, and I want to display it using arrays 10 times (I know the class needs work, i'm not fully done with it yet). Thanks

You need to create the array of objects first.

DVD library[] = 
{ {"itsTitle","itsGenre","itsDescription","itsDate_rented","itsDate_returned","itsRating}, ...repeat another 9 times  ... };


You will have to dream up all the relevant data.

Once you've got that you can design a dedicated overloaded <<operator or
cout << library[0].getTitle() << ' ' << library[0].getGenre() etc etc

and loop through the library one at a time.

I showed you how to create an array of DVDs and how to create both a read and a print function in your previous thread.
http://www.cplusplus.com/forum/beginner/195459/#msg940210

Why are you asking the question again?
If you did not understand what I posted, then please indicate what you did not understand.

The only thing I did not show you in that post was how to print the array of DVDs.

  DVD library[10];  // Using kemort's name for the array

  //  Load the data to the array somehow
  //  Print each element of the array
  for (int i=0; i<10; i++)
    library[i].Print(cout);

I suggest you close this thread off with the solved green tick. Then only use the other thread.

Please don't open any other threads on any other assignment problems until that one is solved and green ticked. :)

Great, thanks Kemort! I'll do that!
