Nested For Loop:-


 We will use more than one for loop using nested sequence using inner for loop and outer for loop. The outer for loop executes once then the inner for loop will be executed when the inner condition will be false then outer for loop will increase when the outer for loop condition will false then the loop will be terminated.


We can create a pattern-based program using nested for loop.

for(init;condition;iteration)
{
   for(init;condition;iteration)
   {
          Statement;
   }

}

For example, if we want to create the following pattern:-

1 2 3 4 5
1 2 3 4
1 2 3
1 2
1
...............................................................................................................................

for(int i=5;i>=1;i--)
{
      for(int j=1;j<=i;j++)
    {
            Console.Write(j+" ");
    }
     Console.WriteLine();

}

  1. Series of Prime number?


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

    namespace seriesof_prime_no
    {
    class Program
    {
    static void Main(string[] args)
    {
    int i, j, n=50;
    for (i = 2; i <= n; i++)
    {
    int c = 0;
    for (j = 1; j <= i; j++)
    {
    if (i % j == 0)
    {
    c++;
    }
    }

    if (c == 2)
    {
    Console.WriteLine(i);
    }
    }
    Console.ReadKey();
    }
    }
    }

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

    for (int i = 1; i <= 5; i++)
    {
    int asc = 65;
    for (int j = 1; j <= 6 - i; j++)
    {
    if (j % 2 != 0)
    Console.Write((char)asc + " ");
    else
    {
    Console.Write((char)(asc + 32) + " ");
    asc++;
