Alright, how do i print a given number of a symbol per row, and then one less each row untill there is none left?

Question: Can i link "Console.Write("#"); - to the value of x or Y?

like this picture: http://csharpskolan.se/image.php?id=115[^]

My code is currently:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Oh Herro!");
            for (int y = 10; y >= 1; y--)
            {
                for (int x = 10; x >= 0; x--)
                {
                    Console.Write("#");
                }
             Console.WriteLine();
            }
        }
    }
}

Solution 1

I know it's homework, but we get so few opportunities to actually answer with code. Here's one way to do it:

C#

string pounds = "##########";

Console.WriteLine("Oh Herro!");
for(int i = 0; i < pounds.length; i++)
{
    Console.WriteLine(pounds.SubString(i));
}
Console.WriteLine();

It's not homework. i'm trying to learn it by myself =)
So what i do is i make a string with the number of #'s i want and then make the loop last as many letters there are in pounds string..

Then it writeline(pounds.[b]substring(i)[/b]);

That part i did not understand. Correct me if i'm wrong... but does pounds.substring(i), write the value of i, in letters of pounds?
Or what does substring mean?

Mathematical terms: Let a string be "WELCOME" then it may be considered as a set of letters 'W' 'E' 'L' 'C' 'O' 'M' 'E' a substring is a subset of this set like "ELCO"
which can be expressed as subtring starts 2nd char and length is 4 chars.
the statement in question means it starts at 1st char(because there is 1 number given starting letter is by default 1st one) and ends at i th char where "i" is the variable which represents the length of each line in the picture you sent.

Look up string.Substring in google, and you'll see why this will work. The overload I'm using will return a substring of the original starting at the specified index (i in my example).

Improvement:
x = 10;
string pounds = new string('#',x);
:-)

Member 7896310 4-May-11 11:18am

So that gives the ammount of '#' as a factor of the x value?

yesotaso 4-May-11 11:28am

Yes. And like Mr. Simmons said take a look around in this site and see Beginner section of c# or VB. In addition Google is your friend.

Solution 3

try this :)

C#

static void Main(string[] args)
        {

            for (int y = 1; y <= 10; y++)
            {
                for (int x = 10; x >= y-1; x--)
                {
                    Console.Write("#");
                }
                Console.WriteLine();

            }
            Console.WriteLine("Oh Herro!");
            Console.ReadLine();

        }

This was exactly the one i was looking for! The lesson said "that the inner loop should use values from the outer loop".. Thank you very much!!!
