grammar

C #nested switch statement syntax:

switch (ch1) 
{
   case 'A': 
      printf ( "This A is part of the external switch");
      switch (ch2) 
      {
         case 'A':
            printf ( "This is part of the internal switch of A");
            break;
         case 'B': / * internal B case the code * /
      }
      break;
   case 'B': / * External B case the code * /
}

Examples

using System;

namespace DecisionMaking
{
    
    class Program
    {
        static void Main (string [] args)
        {
            int a = 100;
            int b = 200;

            switch (a)
            {
                case 100:
                    Console.WriteLine ( "This is part of an external switch.");
                    switch (b)
                    {
                        case 200:
                        Console.WriteLine ( "This is an internal switch part");
                        break;
                    }
                    break;
            }
            Console.WriteLine ( "a precise value is {0}", a);
            Console.WriteLine ( "b the exact value is {0}", b);
            Console.ReadLine ();
        }
    }
} 

When the above code is compiled and executed, it produces the following results:

This is an external switch which is part of the exact value of the internal switch is part of a 100
b The exact value is 200
