Need help just writing a fragment of code in C++, the code is incomplete I just need help writing the constructor. I have highlighted the area that needs the code added in

Write a public default constructor for signal_handler_op as follows:

• construct the type_ member with op_type::default_, and,
• constructs sa_handler_ with the value of DEFAULT

Code Below:

class signal_handler_op {

private:

enum class op_type { error, default_, ignore, traditional, sigaction };

public:

using traditional_op_type = void(*)(int); using sigaction_op_type = void(*)(int, siginfo_t * , void *);

private:

traditional_op_type static const ERROR;

traditional_op_type static const IGNORE; traditional_op_type static const DEFAULT;

op_type type_;

union { traditional_op_type sa_handler_; sigaction_op_type sa_sigaction_; };

public:

/* FIX/FINISH THE CODE BELOW */

signal_handler_op(): default; //default constructor

type_ op_type::default_
