✅ Creating arrays

I’m coming from C where I can either create an array by doing int num[]={…}; or int num[2];

It seems that for C# there are many different ways to do it. I understand int[] x = {1,2,3}; and int[] x = new int[3];

I am confused on how int[]x = new int[] {1,2,3}; works, I am confused on how this isn’t the same as int[] x = {1,2,3};

Also am I able to just do int[] x?

You can do int[] xint[] x but you won’t be able to do anything with it until you definitely assign it.

int[] x = new int[] { 1, 2, 3, };

int[] x = new int[] { 1, 2, 3, };

and

int[] x = { 1, 2, 3, };

int[] x = { 1, 2, 3, };

and

int[] x = [ 1, 2, 3, ];

int[] x = [ 1, 2, 3, ];

are all the exact same in the end

It seems like if I just have this I can’t use it in my code even if I am assigning it

But it works if I started the array with new int[10]
