using System; 
 
class MainClass {  
  public static void Main() {  
    int ivar;     // an int variable 
    double dvar;  // a floating-point variable 
 
    ivar = 100;   // assign ivar the value 100 
    
    dvar = 100.0; // assign dvar the value 100.0 
 
    Console.WriteLine("Original value of ivar: " + ivar); 
    Console.WriteLine("Original value of dvar: " + dvar); 
 
    Console.WriteLine();            // print a blank line 
 
    // now, divide both by 3 
    ivar = ivar / 3;  
    dvar = dvar / 3.0; 
 
    Console.WriteLine("ivar after division: " + ivar); 
    Console.WriteLine("dvar after division: " + dvar); 
  }  
}

Original value of ivar: 100
Original value of dvar: 100

ivar after division: 33
dvar after division: 33.3333333333333
