Value passing and reference passing 02

Let's take another look at the example of value passing and reference passing:

            // value is passed, passing the value itself            . int Ten ;             int m = N;              + ;            Console.WriteLine (n);    // Ten            Console.WriteLine (m);   //  +

 //  
    
     //
     P1 P2 points to the address on the same heap  //  Changing the age that age,p1 points to by P2 changes the  person p1 = new   person ();            P1.age  = 20  ;            person P2  = P1;            P2.age  = 25  ;  Console.WriteLine (P1.age);  //   Console.WriteLine (p2.ag  e); //  

 // //  
     
      string 
      S1 =  DSSD   " ;             string  s2 = S1; S2  =  rere   "             //  DSSD  Console.WriteLine (s2 ); //  Rere  

            // Precede the argument with a ref modifier, passing the address of the parameter, passing the value to the reference pass            int Ten ;            Fun (ref number );            Console.WriteLine (number);   //    -         Public Static void Fun (refint  N)         {            ten;        }
