Write a definition for an exception class, E, that contains an error number and a string type error name. Include a constructor that creates an E object and initializes both members. Provide accessors for both the message and error number.

What will be an ideal response?

```
#include
using namespace std;
class E
{
public:
E(int theError, string theMessage);
string what();
int errorNumber();
private:
int errorNo;
string message;
};

int E::errorNumber()
{
return errorNo;
}
string E::what()
{
return message;
}
E::E(int Err, string Msg) : errorNo(theError),
message(theMessage){/*empty*/}
```
