stackcomposition.h

是有关C++编程原理教程的例子程序,全,应该对大家有所帮助

// Fig. 21.15: Stackcomposition.h
// Template Stack class definition with composed List object.
#ifndef STACKCOMPOSITION_H
#define STACKCOMPOSITION_H

#include "List.h" // List class definition

template< typename STACKTYPE >
class Stack 
{
public:

   // push calls stackList object's insertAtFront member function
   void push( const STACKTYPE &data )

      stackList.insertAtFront( data ); 
   } // end function push
   
   // pop calls stackList object's removeFromFront member function
   bool pop( STACKTYPE &data ) 
   { 
      return stackList.removeFromFront( data ); 
   } // end function pop
   
   // isStackEmpty calls stackList object's isEmpty member function

      return stackList.isEmpty(); 
   } // end function isStackEmpty
   
   // printStack calls stackList object's print member function
