Trailing Zeros
I'm currently implementing / Simulating a list and have created a Sort method, which implementes bubble sort. For some reason, every time I expand the size of my internal array, I have trailing zeros and have no idea how to get rid of them. I have a feeling that the problem might be the way I compare the values.
Does anyone know how I can get rid of the zeros at the end?

do you have an example that demonstrates the issue you're seeing?
arrays don't have a capacity like lists, the size is always equal to the number of elements in the array
so if you resize an array, the new slots will contain the default value for the type (in this case, 0)
I just realised that the problem might be how I implemented the insert method.
I'm currently trying something brb
nvm
This is how it looks like
This is how the add method looks likee
to me it looks like you're not properly using your
_count throughout your class
you're adding 6 items which causes your code to end up with an 8 element backing array
the zeroes aren't really "in" the collection, they're just unused elements in the array that your class shouldn't be exposing or touchingUnknown User•5w ago

Yeah, but I can't use my _count, because it just keeps track of my index and doesn't really show the actual size of my array

But for classes the value is null, so I can simply use another method to exclude all the null values

No sure, is it because there aren't any values? just empty spaces
Like nothing

Well I know value types are copies of the original and references point to the memory
Is that correct?

Had C, but since it was only last year we didn't learn that much. The main programming language is C#

Na, we didn't get to that point

I just realized that I can't really understand anything under the term "memory"

0
So if no value is inserted in the array, then you have zeros, correct?

In terms of defaults values though, correct?

That's why it's immutable?

I just realized it doesn't display the "trailing zeros" for string

But does it make any difference in this case, whether i use _count or Count
Unknown User•5w ago

Count returns _count

No

The Interface forced me to implement both

So I don't need both?

It doesn't now
I removed the second one and there's no error

public IEnumerator<T> GetEnumerator()
{
return new MyListEnumerator<T>(_myList);
}
Like this?
How do you send the codes like this
or do you mean this
public class MyList<T> : IEnumerable<T>?
