Fehlt da eine "( )" um das "*" oder ka....was ich noch machen könnte.

mehrere rohe Zeiger in einer Klasse sind in der Regel keine gute Idee. Das ist recht schwer exception-sicher zu bekommen.

#include <iostream>
#include <algorithm>
using namespace std;

class Event
{
    public:
    Event(int a_, int b_, int c_);
    Event(const Event &rhs);
    ~Event();
    const Event & operator= (const Event & rhs);
    void swap_obj(Event & object);

    private:
    int *m_a;
    int *m_b;
    int *m_c;
};

Event::Event(int a_, int b_, int c_)
:m_a(new int(a_)),
 m_b(new int(b_)),
 m_c(new int(c_))
{

}

Event::Event(const Event &rhs)
:m_a(new int(*rhs.m_a)),
 m_b(new int(*rhs.m_b)),
 m_c(new int(*rhs.m_c))
{

}

Event::~Event()
{
    delete m_a;
    delete m_b;
    delete m_c;
}

const Event & Event::operator= (const Event & rhs)
{
    Event temp(rhs);
    swap_obj(temp);
}

void swap_obj(Event & object)
{
    swap(m_a,object.m_a); //<--!
    swap(m_b,object.m_b); //<--!
    swap(m_c,object.m_c); //<--!
}

int main()
{

    return 0;
}

Weil du bei der Funktion die Klasse vergessen hast

void Event::swap_obj(Event & object)
{
    swap(m_a,object.m_a); //<--!
    swap(m_b,object.m_b); //<--!
    swap(m_c,object.m_c); //<--!
}

So sollte es gehen.
rya.
