Create an implementation file (myString.cpp) in C++ for the following header (myString.h) and test file (test.cpp).

HEADER FILE:

class myString

{

public:

myString(const char *charString = ""); //links to pointer

myString(const myString &other); //copy const - only has one arg. and is passed by ref.

void operator = (const myString &other); //assignment operator

~myString(); //destructor is preceded by ~

int getLength() const; //returns length

char operator [ ] (int n) const; // will take int locations and return a char from string

void clear(); // makes head null

void showStructure() const; //print string

myString toupper() const; //convert a -> A

myString tolower() const; //conver A->a

bool operator == (const myString& other) const; //equal length

bool operator < (const myString& other) const; //less than length

bool operator > (const myString& other) const; //greater length

private:

// Data members

int myStringSize;

char *Arr;

// myString input/output

friend istream & operator >> (istream& input, myString& inputmyString); //can access private data members

friend ostream & operator << (ostream& output, const myString& outputmyString); //friend only in h file purpose is to outputstring

};

#endif

TEST FILE:

#include

#include "myString.h"

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

// Function prototype

void copyTester(myString copymyString); // copymyString is passed by value

void print_help();

char ch, // Character specified by subscript

selection; // Input test selection

// Get user test selection.
