How do I randomly select a value for an enum type in C++? I would like to do something like this.

enum my_type(A,B,C,D,E,F,G,h,J,V);
my_type test(rand() % 10);

But this is illegal... there is not an implicit conversion from int to an enum type.

How about:

enum my_type {
    a, b, c, d,
    last
};

void f() {
    my_type test = static_cast<my_type>(rand() % last);
}
