Answer 1

Here I have created a number pyramid:

using System;

public class Program
{
   public static void Main()
   {
      Console.WriteLine("This is a number pyramid....");
      var rows = 5;

      for(int i = 1; i <= rows; i++)
      {
         for(int lsc = (-rows); lsc <= -2; lsc ++)
         {
            if(lsc < (-1)*i)
            {
               //write left sided blank spaces
               Console.Write(" ");
            }
            else
            {
               //write left sided numbers
               Console.Write(-1*(lsc));
            }
         }

         for(int rsc = 1; rsc <= rows; rsc++)
         {
            //write right sided blank spaces
            Console.Write(" ");
         }
         else
         {  
            //Write sided numbers
            Console.Write(rsc);
         }
       } 
      Console.WriteLine();
    }
  }
} 

I have described here https://utpalkumardas.wordpress.com/2018/04/20/draw-number-pyramid

Out put is:

The is a number pyramid....
        1
      212
    32123
  4321234
543212345

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

namespace Star_Pyramid
{
    class Program
    {
        static void Main(string[] args)
        {
            Program o = new Program();
            o.show();

            Console.ReadKey();
        }
        void show()
        {
           for (int i = 1; i <= 12; i++)
            {
                for (int j = 1; j <= 9 - i / 2; j++)
                {
                    Console.Write("   ");
                }
                for (int k = 1; k <= i; k++)
                {
                    Console.Write(" * ");
                    Console.Write(" ");


                }
                Console.WriteLine();

            }
        }
    }
}

Answer 3

Try this and follow this same logic in c, c++, php, java

using System;

class pyramid {

      static void Main() {

           /** Pyramid stars Looking down 
               Comment this if u need only a upside pyramid **/

           int row, i, j;

           // Total number of rows
           // You can get this as users input 
           //row =  Int32.Parse(Console.ReadLine());
           row = 5;             

           // To print odd number count stars use a temp variable
           int temp;
           temp = row;

           // Number of rows to print 
           // The number of row here is 'row'
           // You can change this as users input 
           for ( j = 1 ; j <= row ; j++ ) { 

           // Printing odd numbers of stars to get 
           // Number of stars that you want to print with respect to the value of "i"?         
               for ( i = 1 ; i <= 2*temp - 1 ; i++ )
                   Console.Write("*");

           // New line after printing a row            
               Console.Write("\n");
               for ( i = 1 ; i <= j ; i++ )                
                   Console.Write(" ");

           // Reduce temp value to reduce stars count                  
               temp--;
           }

           /** Pyramid stars Looking up 
               Comment this if u need only a downside pyramid **/
           int rowx, k, l;

           // Total number of rows
           // You can get this as users input 
           // rowx =  Int32.Parse(Console.ReadLine());
           rowx = 5; 

           // To print odd number count stars use a temp variable
           int tempx;
           tempx = rowx;

           //Remove this if u use 
           Console.Write("\n");

           // Number of rows to print 
           // The number of row here is 'rowx'

           for ( l = 1 ; l <= rowx ; l++ ) {

           // Leaving spaces with respect to row
               for ( k = 1 ; k < tempx ; k++ )
                   Console.Write(" ");

           // Reduce tempx value to reduce space(" ") count  
               tempx--;

           // Printing stars 
               for ( k = 1 ; k <= 2*l - 1 ; k++ )
                   Console.Write("*"); 

           // New line after printing a row 
               Console.Write("\n");
           }           
      }
}

Answer 4

Your problem is spaces, therefore I suggest you think about the spaces. Tell me this: how many spaces are on each row to the left of the first star? You'll likely be able to solve your own problem if you think about this.

Answer 5

think about how you'd print the pyramid manually.

suppose 5 levels deep.

1st line: 4 spaces, 1 star,
2nd line: 3 spaces, star, space, star
3rd line: 2 spaces, star space star space star

etc.

doesn't matter whether you print spaces after the last star or not - won't make a difference to how it looks.

what do we see?

if we have a total of X levels

line 1: (x-1) spaces, (star space)
line 2: (x-2) spaces, (star space) twice
line 3: (x-3) spaces, (star space) three times
line 4: (x-4) spaces, (star space) four times

that's the pattern. I'll leave the coding to you.

Answer 6

using System;

    class Program
    {
        static void Main(string[] args)
        {
            int num, i, j, k;
            Console.Write("enter the level:");
            num=Convert.ToInt32(Console.ReadLine());
            for (i = 1; i <= num; i++)
            {
                for (j = 1; j < num-i+1; j++)
                {
                    Console.Write(" ");
                }
                for (k = 1; k <= i; k++)
                {
                    Console.Write(i);
                    Console.Write(" ");
                }
                Console.WriteLine();

            }
        }
    }
