Menu.h

#pragma once

#include <iostream>
#include <cstring>

using namespace std;

class Menu
{
private:
	string title;

public:
	Menu( void );
	Menu( const Menu &unMenu );
	~Menu( void );

	void setTitle ( string title );
	string getTitle() const;
};

Menu.cpp

#include "Menu.h"

Menu::Menu(void)
{
	this->title = "Hello";
}

Menu::Menu(const Menu &unMenu)
{
	this->title = unMenu.title;

}

Menu::~Menu(void)
{
}

///////////////////////////////////////////////////

void Menu::setTitle( string title )
{
	this->title = title;
}

string Menu::getTitle() const
{
	return ( this->title );
}

main.cpp

#include "Menu.h"

#include <iostream>
#include <cstring>

using namespace std;

int main ()
{
	Menu m;

	m.setTitle( "Spider Man 3" );
	cout << m.getTitle();

	system("PAUSE");
	return 0;
}

I'm getting a problem when i put
cout << m.getTitle();

Use
#include <string>
instead of
#include <cstring>

Use
#include <string>
instead of
#include <cstring>

That Fixed the Problem. Thanks

can you tell me what's the difference between
<cstring> & <string>

When do we use each one ?

I only know that <cstring> is more recent.

tx.

cstring replaces string.h which is where a lot of the standard functions to manipulate C style strings (null terminated char array) are located. string is the header for the STL string class and it contains the functions to manipulate STL string objects.

The quick answer is that <cstring> is the C++ version of the old C header file string.h, while <string> is the std::string class from C++.

There is probably a long answer about the history of C and C++ and MFC and OLE, and it probably has something to do with Unicode but it is beyond my knowledge.

I'll take your word for it that <cstring> is newer, and it just goes to show that newer is not always better.

<cstring> aka <string.h> is not more recent. It is the old C string stuff.

The only thing that is recent about it is the ability to refer to it as <cstring> instead of <string.h>.

" <cstring> aka <string.h> is not more recent. It is the old C string stuff."

Is that the CString thats available in MFC is also the same the old C string stuff. Is Microsoft reinvented the wheel or its their own implementation.

[Duoas]

No, this is C++. Refer to old files like <string.h> as <cstring>.

Microsoft's CString is older than std::string, but far more recent than the old C-style string handling routines.

The code is too big to read. Why dont you zip and upload the project and indicate the problem function. It will be easy to debug.
