std::set - How do i alter element in list?

[maybnxtseasn]

How do i alter an element in the set for example how do i edit the 'm_a' member variable of a element in my set?

class CPerson
{
    public:
    int m_a;

    CPerson(int _a)
    {
        m_a = _a;
    }
}

set<CPerson*> myPersonSet;
..
...
set<CPerson*>::iterator it = myPersonSet.find( CPerson(20) );

// How do i change the value of the object i found in my list once i found it and it's referenced by my iterator?

You aren't showing enough code. What is the element that defines the set member? Is that being changed?

(*it)->m_a = 10;
