Question

I could use help, me please:

Write a program (in main.cpp) that:

Prompts the user for a filename containing node data.
Outputs the minimal spanning tree for a given graph.

You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix.

Note: Files Ch20_Ex21Data.txt and Ch20_Ex4Data.txt contain node data that you may test your program with.

minimalSpanTreeType.h:

#ifndef H_queueADT

#define H_queueADT

template <class Type>

class queueADT

{

public:

virtual bool isEmptyQueue() const = 0;

//Function to determine whether the queue is empty.

//Postcondition: Returns true if the queue is empty,

// otherwise returns false.

virtual bool isFullQueue() const = 0;

//Function to determine whether the queue is full.

//Postcondition: Returns true if the queue is full,

// otherwise returns false.

virtual void initializeQueue() = 0;

//Function to initialize the queue to an empty state.

//Postcondition: The queue is empty.

virtual Type front() const = 0;

//Function to return the first element of the queue.

//Precondition: The queue exists and is not empty.

//Postcondition: If the queue is empty, the program

// terminates; otherwise, the first

// element of the queue is returned.

virtual Type back() const = 0;

//Function to return the last element of the queue.

//Precondition: The queue exists and is not empty.

//Postcondition: If the queue is empty, the program

// terminates; otherwise, the last

// element of the queue is returned.

virtual void addQueue(const Type& queueElement) = 0;

//Function to add queueElement to the queue.

//Precondition: The queue exists and is not full.

//Postcondition: The queue is changed and queueElement

// is added to the queue.

virtual void deleteQueue() = 0;

//Function to remove the first element of the queue.

//Precondition: The queue exists and is not empty.

//Postcondition: The queue is changed and the first

// element is removed from the queue.

};

#endif
