Frogleg · Answer

One way class Program { static string[] ast = new string[4] {  *  ***  ***** ******* }; static void Main(string[] args) { for (int i = 0; i { Console.WriteLine(ast[i]); } for (int ii = 2; ii >= 0; ii--) { Console.WriteLine(ast[ii]); } } }

Sam Hobbs · Answer

Yes char is initialized to 0. So I am sure there is a 1-line code for initializing the char items to spaces if it was important.

Vulpes · Answer

Sam A char[] is in fact initialized to null chars '\0' but it doesn't matter because Console.WriteLine() writes them to the console as though they were spaces :) Frogleg LOL ;)

Stars stars everywhere Asterisk you take when you play with stars

Sam Hobbs · Answer

This is not the simplest but I think it is an alternative that satisfies the requirements. I assume that a char is initialized to a space character. char[] Stars = new char[7]; Stars[3] = '*'; for (int i = 0; i { Console.WriteLine(Stars); Stars[2 - i] = '*'; Stars[4 + i] = '*'; } for (int i = 2; i >= 0; --i) { Console.WriteLine(Stars); Stars[2 - i] = ' '; Stars[4 + i] = ' '; } Console.WriteLine(Stars);

Yep IE8

Vulpes · Answer

I've just looked at the HTML for the page and the problem is that your browser (IE perhaps?) is not inserting non-breaking spaces and so multiple spaces are being compressed to a single one when the page is rendered. Mine on the other hand (Google Chrome) is inserting non-breaking spaces for the first two items and so no compression takes place.

Strange re static string[] ast = new string[4] {  *  ***  ***** ******* }; as it is Ok in the ide and I just pasted it fron there Anyway Anil has two ways of doing it now

Vulpes · Answer

I've used it because both 'i' and 'j' can be negative but we need to provide symmetry whether they're positive or negative. If you remove the Math.Abs you'll find that it doesn't work correctly.

Anil Kumar · Answer

Hi vulpes why you have use Math.Abs function???

Vulpes · Answer

I suspect that Frogleg's browser may be condensing multiple spaces into a single space as his first line should of course be: static string[] ast = new string[4] {  *  ***  ***** ******* }; Although it's not what the OP asked for there's also an easy way to do this without using an array: class Program { static void Main() { for(int i = -3; i { for(int j = -3; j Console.WriteLine(); } } }
