Which of these exception specifications is correct, and why?

Question

Suppose we have the class definitions, where the exception specification is as listed
below:
```
class B{public: virtual void f() throw(int,
double);};class D:public B{public: virtual void f()
//The exception specification you
//choose from the list goes here.
```

a) Use no exception specification.
b) throw ( )
c) throw(int)
d) throw(int, double)
e) throw(int , double, string)
f) throw(double);
g) None of these, because you can’t derive from a class where member functions
have exception specifications.

Answer 1

b) throw ( )
c) throw(int)
d) throw(int, double)
f) throw(double);
