❔ Can anyone help explain what it's talking about?

Is it trying to get me to copy the array value from arrayOne to arrayTwo? If so, how? It never taught me that, only how arrays work.

Arrays - C#

Store multiple variables of the same type in an array data structure in C#. Declare an array by specifying a type or specify Object to store any type.

- what is this "it" that never taught you - yes, you are suppose to copy the elements of arrayOne into arrayTwo by iterating over arrayOne - arrayTwo should not have been declared with values defined, just a size matching arrayOne - if you know how arrays works then you can do the requested task. * read the value of arrayOne index 0 and write it to arrayTwo index 0 and so forth for each index

I understand the basic of what it is but I guess not to this point unless we were to assigned arrayTwo to equal arrayOne like this string[] arrayOne = arrayOne Would like to read it but if I tried.... I'm not learning anything

How does reading something = not learning?

MRW419OP•15mo ago

Cause it just doesn't make sense if I read it Someone explaing it through video is easier for me to learn

Protip: you can set the value of an array at a given index using theArray[index] = newValue That and a loop should be all you need

MRW419OP•15mo ago

Thank you, I'll mess around and see what I can do Quick question do we use the arrayTwo?

Angius•15mo ago

Well, yes That's the task, isn't it? To copy values from one array to the other

MRW419OP•15mo ago

Got it, just maklng sure oh, well I mean for the theArray[index]

Angius•15mo ago

That's also the way to access a value at a given index, yes

REPL Result: Success

void Print<T>(T[] arr) => Console.WriteLine(string.Join(", ", arr));

var arr = new[]{ 1, 2, 3 };
Print(arr);
arr[1] = 69;
Print(arr);
Console.WriteLine(arr[0]);

void Print<T>(T[] arr) => Console.WriteLine(string.Join(", ", arr));

var arr = new[]{ 1, 2, 3 };
Print(arr);
arr[1] = 69;
Print(arr);
Console.WriteLine(arr[0]);

Console Output

1, 2, 3
1, 69, 3
1

1, 2, 3
1, 69, 3

You only change one number. I have to copy all of the vaule from arrayOne to arrayTwo

SinFluxx•15mo ago

That's where the loop comes in

MRW419OP•15mo ago

Oh, so do

var arr = new[]{1, 2, 3 };
print(arr);
for (int i = 0; i < arr.Length; i++
{
   arr[i] = 69;
}

var arr = new[]{1, 2, 3 };
print(arr);
for (int i = 0; i < arr.Length; i++
{
   arr[i] = 69;
}

Wait is arr arrayTwo? if so then where is the value of arrayOne?

int[] arrOne = {1, 5, 6};
var arrTwo = new[]{1, 2, 3 };
print(arrTwo);
for (int i = 0; i < arrTwo.Length; i++)
{
   arrTwo[i] = arrOne;
}

int[] arrOne = {1, 5, 6};
var arrTwo = new[]{1, 2, 3 };
print(arrTwo);
for (int i = 0; i < arrTwo.Length; i++)
{
   arrTwo[i] = arrOne;
}

Get the specific item from arrayone Insert 0th item from arrayOne into 0th spot in arrayTwo, 1st into 1st, and so on

MRW419OP•15mo ago

Could you show me?

Kouhai•15mo ago

How do you iterate over an array using a for loop?

Angius•15mo ago

Here, I highlighted the relevant parts

MRW419OP•15mo ago

Hm? What about those? Shoulden't it be covered in the for loop?

Angius•15mo ago

The first highlight shows you how to set an item in the array at index 1 The second shows you how to get an item from the array at index 0 You want to insert an item from the first array's index n to the second array's index n Where n is, well, each index That's where the loop comes in

((Sorry got out of school but i'm back)) I think I got it....
