Clearing specific parts of an array

[XemMeg]

Hi everyone! Let's say I have an array of structures:

struct Party
        {
	char *	pName;
	int		NumPeople;
	char	Plane;
	};

Party List [5];

And let's say List is populated as follows:

List [1] = Alfa Stevenson 2
List [2] = Beta Dorothy 1
List [3] = Alfa Adam 3

where Alfa/ Beta are different groups you're trying to sort the Parties into.
So I'm going to move List [2] to another array (prewritten)...and then 'shift' the rest of the list up one.

Party Beta [5];
Beta [0] = List [2];

for (i = 2; i < 5; i++)
     List [i - 1] = List [i];

But when this runs, array is populated as below.

List [1] = Alfa Stevenson 2
List [2] = Alfa Adam 3
List [3] = Alfa Adam 3

So my question is (FINALLY), How do I get rid of this issue of having two copies of the last party? If I was to populate List [3] with spaces..would it be possible to wrote over List [3] with new input?

Thank you!

Maybe this would work better as a linked list instead of an array.

I'm afraid I haven't learned how to do those yet. Can you think of any solution to the array issue?

You need to keep a note of the number of items in the array. Then use that as your top exclusive bound:

Party List [5];
int end = 5;

Party Beta [5];
Beta [0] = List [2];

for (i = 2; i < end; i++) // only iterate up to (not including) end
     List [i - 1] = List [i];
--end; // decrement end point 

As helios said this would be better done with std::list, unless its an assignment.
