Explanation

There cannot be a CV qualifier. In C ++, the CV qualifier refersconstAndvolatile.

• Non-member functions

In C ++, normal functions (non-class member functions) cannot have CV restrictions, that isconstAndvolatileLimitation. That is, the number of non-class member rows.constModify:

Int test () const // This is incorrect. Normal Functions (non-member functions cannot have CV constraints) {// implement}

• Static Functions

In C ++, static member functions (staticMember functions) cannot have CV restrictions, that isconstAndvolatileLimitation. That is, the static member functions of the class cannot have CV constraints:

Class test {public: static int test_fun () const; // This is not allowed .}
