Problems with allocation

[Guest]

Hello

I have a problem. The following program throws a "0" instead of a "25". I´m from the JAVA world, and in JAVA the output is "25"

Hope, anybody can help me

Thanks ..


class Content

public

Content()
wert = 0

Content::~Content()


int getValue()
return value

void setValue(int _value)
value= _value


private
int value
}

--

#include "Content.h

class Container

public

Container()

Container::~Container()


Content getContent()
return content

void setContent(Content _content)
content = _content


private
Content content
}

--

// Allocationproblem.cp
/

#include "stdafx.h
#include <iostream.h
#include "Container.h

int main(int argc, char* argv[])

Container container = Container()
container.getContent().setValue(25)
cout << container.getContent().getValue() << endl

return 0

You need to either return your content object by reference (or pointer), or
supply a copy constructor.
I'd recommend doing both, plus defining an assignment operator.
