Triangle Patterns in C#

Triangle Patterns in CSharp.

Triangle: 1

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Hello_Word
{
    class Program
    {
        Static void Main(string[] args)
        {
            int val = 5;
            int i, j, k ;

            for (i = 1; i <= val; i++)
            {
                for (j = 1; j <= i; j++)
                {
                    Console.Write("");
                }
                for (k = 1; k <= i; k++)
                {
                    Console.Write("*");
                }
                Console.WriteLine("");
            }      
            Console.ReadLine();             
        }
    }
}

Or, you can write it, by doing some minor changes,

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Hello_Word
{
    class Program
    {
        static void Main(string[] args)
        {

           int val = 5;
           int i, j, k ;
            for (i = 1; i <= val; i++)
            {
                for (j = 1; j <= val-i; j++)
                {
             //       Console.Write("");
                }
                for (k = 1; k <= i; k++)
                {
                    Console.Write("*");
                }
                Console.WriteLine("");
            }      
            Console.ReadLine();             
        } 
    }
}

Triangle: 2

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Hello_Word
{
    class Program
    {
        static void Main(string[] args)
        {
            int val = 5;
            int i, j, k ;
 
            for (i = 1; i <= val; i++)
            {
                for (j = 1; j <= val-i; j++)
                {
                    Console.Write(" ");
                }
                for (k = 1; k <= i; k++)
                {
                    Console.Write("*");
                }
                Console.WriteLine("");
            }  
            Console.ReadLine();             
        }    
    }
}

[The way I mentioned for the first triangle, in the same manner you can workout this pattern too, by applying some minor changes:]

Triangle: 3

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Hello_Word
{
    class Program
    {
        static void Main(string[] args)
        {
            int val = 5;
            int i, j, k ;
 
            for (i = 1; i <= val; i++)
            {
                for (j = 1; j <= val-i; j++)
                {
                   // Console.Write(" ");
                }
                for (k = 1; k <= j; k++)
                {
                    Console.Write("*");
                }
                Console.WriteLine("");
            }      
            Console.ReadLine();             
        }    
    }
}
