ENUM(Channel, int, Red, Green, Blue)

int main()

std::cout << +Channel::Red << std::endl;

return 0;

}

|
|
// The thing to watch for is the +: without it, Channel::Red is a value of type
|
|
// Channel::_enumerated, a C++98 enum type, so writing that to cout will output
|
|
// an integer. +Channel::Red, however, is a value of type Channel, and writing
|
|
// that instead will output the string "Red".
|
|
//
|
|
// Input is also supported:
|
|
//
|
|
// Channel channel = Channel::Blue;
|
|
// std::cin >> channel; // Expects input such as "Green".
|
|
//
|
|
// Only char streams are supported for the time being.
