I could not get this const before a function declaration

[parag_paul]

I understand that a const qualifier after the function declaration
makes it a const function for the class.

Like

int func1 const ( double, long int );

Now what is the purpose of the following
const int func1 const ( double, long int );


What is the purpose of the const before the declaration

Actualy, it's like this:

int func1 ( double, long int ) const;

Now what is the purpose of the following
const int func1 const ( double, long int );

const int func1 ( double, long int ) const;

would be a constant function that returns a constant integer. Really not
making much sense, usually a const returned value is a reference or pointer
such as:

const int & func1 ( double, long int ) const;
or
const int* func1 ( double, long int ) const;

Not much sense, since const-ness doesn't apply to rvalues of
non-class type. It is reasonable for a class type.
