Blank Spaces in Char Array

Question

When I run below code, why are spaces output at the beginning?   

        string str1 = "this is a string";

            

            char[] newchar = new char[str1.Length];

            str1.CopyTo(0, newchar, 0, str1.Length);

            

            Array.Sort(newchar);

           

            for (int i=0; i<newchar.Length;i++)

            {

                 Console.Write(newchar[i]);

            }

          

            Console.ReadKey();

Answer 1

Because there's a space between "this" and "is", another space between "is" and "a", and and a third space between "a" and "string".

And when you sort the array, spaces come before letters.

Answer 2

Hello CG,

If you don't want  the whitespaces occurs , just edit some code as below.

 string str1 = "this is a string";
 str1=str1.Replace(" ","");
 char[] newchar = new char[str1.Length];
  ...

Sincerely,

Or to answer the "why" part, take a look at the ASCII table and see what is the numeric value of "Space" and other characters.
