D语言使用指针

import std.stdio; 

void main () { 
   int var = 20;   // actual variable declaration. 
   int *ip;        // pointer variable
   ip = &var;   // store address of var in pointer variable  

   writeln("Value of var variable: ",var); 

   writeln("Address stored in ip variable: ",ip); 

   writeln("Value of *ip variable: ",*ip); 
}
