I need help with a program. I have implemented that following header file with an unordered list using one array, but i need to be able to use an ordered list and 2 arrays (one for the links and one to use as an index to the freearray cells).
Here is the exact problem specifications:
Create an ordered list template class named OLType to implement an ordered list with operations of insert, remove, print, empty, full, size. The storage structure is to be a linkedlist emulation using dynamic arrays. It will require a minimum of two arrays, one for the data and one for the 'next' links. The 'free' list can be incorporated into the 'next' links array if done correctly. The 'public' portion of your class file must be as follows:
public:
OLType(size_t n=100);
~OLType();
void insert(const T& item);
void remove(const T& item);
void print() const;
size_t size() const;
bool empty() const;
bool full() const;
Here is the code I have so far:
#ifndef OLType_H
#define OLType_H
#include <iostream>
using namespace std;
template <class T>
class OLType {
public:
OLType(size_t n=100);
~OLType();
void insert(const T& item);
void remove(const T& item);
void print() const;
size_t size() const;
bool empty() const;
bool full() const;
private:
size_t MAX_LENGTH;
size_t n; // max number that can be stored in the list
int count; // number of elements in the list
T *data; // pointer to the array that holds the list elements
};
template <class T>
OLType<T>::OLType(size_t n) {
MAX_LENGTH = n;
count = 0;
data = new T[MAX_LENGTH];
}
template <class T>
OLType<T>::~OLType() {
delete [] data;
}
template <class T>
void OLType<T>::insert(const T& item) {
data[count] = item;
count++;
}
template <class T>
void OLType<T>::remove(const T& item) {
int i = 0;
while (i<count && item != data[i])
i++;
if (i<count) {
data[i] = data[count1];
count;
}
}
template <class T>
void OLType<T>::print() const {
int i;
for(i=0; i<count; ++i)
cout << data[i] << " ";
}
template <class T>
size_t OLType<T>::size() const {
return count;
}
template <class T>
bool OLType<T>::empty() const {
return (count == 0);
}
template <class T>
bool OLType<T>::full() const {
return (count == MAX_LENGTH);
}
#endif
Any help with solving this problem would be greatly appreciated. I am not that strong of a programmer and just cannot seem to find the correct way to do this problem. Thank you.
