    Union 2 arrays

    Does anyone know any code to union 2 sets?

    I have a prototype in my header file of:
    Code:
    IntegerSet& unionSet( IntegerSet& otherSet );
    I want to union array c and b and am calling the function by:
    Code:
    c.unionSet( b );
    What code could I use to combine into 1 array in the .cpp file, returning a reference to the array?

    assuming it's an std::set, can't you use operator += ?

    Or maybe the STL set_union function might be of use depending on how the storage of the data elements is implemented?
