memory leaks code

I need to add a desturctor and delete/delete[] to element memory leaks.please read the attached file and code for more infromation, please check my code for solving the memory leaks and let me know what I did wrong so I can fix it ,thank you

Why are you posting code in such a virus-ridden vector as a .doc file!?

The code and details below. Looks like just another finish my homework for me question:

I need to do the following steps to the program:
Add a destructor and delete/delete[ ] as appropriate to eliminate any memory leaks.
Can change all code back to using a string rather than a c-string.
Also set pointers to null as/if needed.
Replace the formatted output method (toString) with an overloaded output/extraction operator, and modify the driver to use the overloaded operator.
Creating a copy constructor for a deep copy is probably not warranted as the title is the only object data member, but use references/pointers as needed in order to suppress the automatic invocation of the copy constructor

Here is the code:

Code:

// Movie.cpp
#include "Movie.h" // include Movie class definition
#include <sstream>
#include <string>
using namespace std;

Movie::Movie() {
	title = new char[1];
	*title = '\0';
	usBoxOffice = nonUSBoxOffice = worldBoxOffice = usRank = nonUSRank =
		worldRank = 0;
}

Movie::Movie(const char * temp) {
	istringstream iS(temp);
	string s;
	getline(iS, s, '\t');
	title = new char[s.length() + 1];
	strcpy(title, s.c_str());
	iS >> usRank >> nonUSRank >> worldRank >> usBoxOffice
		>> nonUSBoxOffice >> worldBoxOffice;
}

const char * Movie::getTitle() const {return title;}
long long Movie::getUSBoxOffice() const {return usBoxOffice;}
long long Movie::getNonUSBoxOffice() const {return nonUSBoxOffice;}
long long Movie::getWorldBoxOffice() const {return worldBoxOffice;}
int Movie::getUSRank() const {return usRank;}
int Movie::getNonUSRank() const {return nonUSRank;}
int Movie::getWorldRank() const {return worldRank;}

const char * Movie::toString() const {
	ostringstream oS;
	oS << "\n\n====================== Movie Information\n"
	<< "\n             Movie Title:\t" << title
	<< "\n    US Rank & Box Office:\t" << usRank << "\t$" << usBoxOffice
	<< "\nNon-US Rank & Box Office:\t" << nonUSRank << "\t$" << nonUSBoxOffice
	<< "\n World Rank & Box Office:\t" << worldRank << "\t$" << worldBoxOffice
	<< "\n";
	char * s = new char[500];
	strcpy(s, oS.str().c_str());
	return s;
}

Too ugly code. Please tag each class, cpp in separate code tags.
Try to organize in sequence.
In the end give main in separate code tag. It's really too hard to read.

This code is terrible.

Code:

title = new char;
title = new char[1];

Both do not make sense, you allocate only 1 char. Use std::string.

I am wondering how memory can leak code.
