Question

I need to change these files to be a template class instead of a typedef.

#ifndef MAIN_SAVITCH_SEQUENCE_H

#define MAIN_SAVITCH_SEQUENCE_H

#include <cstdlib> //provides size_t

namespace main_savitch_3

{

class sequence

{

public:

//TYPEDEFS and MEMBER CONSTANTS

typedef double value_type;

typedef std::size_t size_type;

static const size_type CAPACITY = 30;

//CONSTRUCTOR

sequence();

//MODIFICATION MEMBER FUNCTIONS

void start();

void advance():

void insert(const value_type& entry);

void remove_current();

//CONSTANT MEMBER FUNCTIONS

size_type size() const;

bool is_item() const;

value_type current() const;

private:

value_type data[CAPACITY];

size_type used;

size_type current_index;

};

}

#endif

If it helps any this is number 2(c) on page 350 of "Data structures and other objects using C++".

Explanation / Answer

#include <iostream>
using namespace std;

#ifndef MAIN_SAVITCH_SEQUENCE_H
#define MAIN_SAVITCH_SEQUENCE_H

#include <cstdlib> //provides size_t
template <class T>
class sequence
{

public:

//TYPEDEFS and MEMBER CONSTANTS

T value_type;

T size_t, size_type;

static const T CAPACITY = 30;

   //CONSTRUCTOR

   sequence();

   //MODIFICATION MEMBER FUNCTIONS

   void start();

   void advance();

   void insert(const T & entry);

   void remove_current();

   //CONSTANT MEMBER FUNCTIONS

   T size() const;

   bool is_item() const;

   T current() const;

private:

   T data[CAPACITY];

   T used;

   T current_index;

};

#endif
int main()
{

}
