Declare loop control variable inside the for

    
using  System;  
  
class  MainClass  {      
    public  static  void  Main()  {  
        int  sum  =  0;  
        int  fact  =  1;  
  
        for(int  i  =  1;  i  <=  5;  i++)  {    
            sum  +=  i;    //  i  is  known  throughout  the  loop  
            fact  *=  i;  
        }  
  
        //  But,  i  is  not  known  here.  
  
        Console.WriteLine("Sum  is  "  +  sum);  
        Console.WriteLine("Factorial  is  "  +  fact);  
    }      
}

Factorial is 120
