In C++ please, comment as well, Thank you!

In lab exercises

- Implement the Text ADT (use the declaration in the Text.h file) (40 points)

EXAMPLE:

#ifndef TEXT_H

#define TEXT_H

#include

#include

using namespace std;

class Text

{

public:

// Constructors and operator=

Text ( const char *charSeq = "" ); // Initialize using char*

Text ( const Text &other ); // Copy constructor

void operator = ( const Text &other ); // Assignment

// Destructor

~Text ();

// Text operations

int getLength () const; // # characters

char operator [] ( int n ) const; // Subscript

void clear (); // Clear string

// Output the string structure -- used in testing/debugging

void showStructure () const;

//--------------------------------------------------------------------

// In-lab operations

// toUpper/toLower operations (Programming Exercise 2)

Text toUpper( ) const; // Create upper-case copy

Text toLower( ) const; // Create lower-case copy

// Relational operations (Programming Exercise 3)

bool operator == ( const Text& other ) const;

bool operator < ( const Text& other ) const;

bool operator > ( const Text& other ) const;

private:

// Data members

int bufferSize; // Size of the string buffer

char *buffer; // Text buffer containing a null-terminated sequence of characters

// Friends

// Text input/output operations (In-lab Exercise 1)

friend istream & operator >> ( istream& input, Text& inputText );

friend ostream & operator << ( ostream& output, const Text& outputText );

};

#endif

- Text(), operator=() and ~Text(), getLength(), clear(), operator[]

Homework exercise

- Programming Exercise 2: Implement the functions toUpper() and toLower() and test them by activating LAB1_TEST1 (30 points)

- Programming Exercise 3: Implement the operators ==, <, > and test them by activating LAB1_TEST2 (30 points)
