why compiler doing this worst , i kindly request the developer to recorrect the whole course itself …

you can use 2 methods ,

using System;
namespace EditingArrays

{
class Program
{
static void Main(string args)
{

  string[] summerStrut;
  summerStrut = new string[] { "Juice", "Missing U", "Raspberry Beret", "New York Groove", "Make Me Feel", "Rebel Rebel", "Despacito", "Los Angeles" };
  int[] ratings = { 5, 4, 4, 3, 3, 5, 5, 4 };
  
  // use general code // in this compiler its not  working
  summerStrut[summerStrut.Length-1]="Cardi B’s I Like It";
  // use specific code
  summerStrut[7]="Cardi B’s I Like It";

  // use general code // in this compiler its not  working
  ratings[ratings.Length - 1]= 3;
  // use specific code
  ratings[7]= 3;

}

}
}

So I have a question with the editing arrays chapter in the C# course.

  1. // plantHeights will be equal to [0, 0, 0]

  2. int plantHeights = new int[3];

  3. // plantHeights will now be [0, 0, 8]

  4. plantHeights[2] = 8;

I would just like some clarification as to how in line 2 the new int[3] sets the array length to three 0’s. I was under the impression that the square brackets after the int meant that it was referencing the value in the third index. Which following that thought process, wouldn’t it then be four 0’s instead of three?

Can someone please explain this to me?

Hi,

In Answer to your question when first initializing an Array without any values

int [] plantHeights = new int[3];

The array will auto allocate a value for each available space in the array, this would be equal to a “0” for an int array and “null” for a string array therefore we get the following:

int plantHeights = new int[3];
// plantHeights will show [ 0, 0, 0 ]

Then we can add a value into the array:

plantHeights[3] = 8;
// plantHeights will now show [ 0, 0, 8 ] because we have replaced the default “0” in the third position to an “8”

I hope this helps in answer to your question.
