Problem: I want to pass an Enum as an integer reference.

Solution:

void MyFunc ( int& MyInt )
{
std::cout << "Value is:" << MyInt << std::endl;
}

enum Enumerator
{
ZERO = 0,
ONE,
TWO,
THREE
};

int main()
{
Enumerator MyEnum = ONE;

if ( sizeof( MyEnum ) == sizeof( int ) )
MyFunc( *reinterpret_cast<int*>( &MyEnum ) );
}

Is this guaranteed to work if sizeof( Enumerator ) == sizeof( int ) ?

By work I mean is this program guaranteed to output 1 in all cases?
