Do i need to delete objects that i set in class member when i replace them?
<p>I have the following:</p>

<pre><code>class Manager{
public:
    void update(list&lt;Employe&gt; employees){
        employees_ = employees;
    }
private:
    list&lt;Employe&gt; employees_;
};
</code></pre>

<p>do i need to delete old employees in the end of update method?</p>
