std::set iterator automatically const [duplicate]

Answer 1

I you are certain you won't touch the variables that are used for the sorting the you could work around this by using a const_cast like this:

    MyClass tmpClass;
    std::set setMyClass;
    setMyClass.insert(tmpClass);
    std::set::iterator iter;
    iter=setMyClass.begin();
    const MyClass &tmpClass2=*iter;

    MyClass &tmpClass3 = const_cast(tmpClass2);

Alternatively, you could declare the members of the class that you intend to change as mutable.
