Error and warning messages in C + + programming (1) cannot have Cv-qualifier

Explanation

There is no CV qualifier, and in C + + the CV qualifier refers to const and volatile.

Non-member function

In C + +, normal functions (non-class member functions) cannot have CV qualification, that is, const and volatile qualification. That is, the number of member rows that are not classes, decorated with const:

iint

test () const // This is wrong, ordinary functions
{
     // implement
}

static functions

In C + +, a static member function (a static member function) cannot have a CV qualification, that is, a const and a volatile qualification. This is the static member function of the class, and there is no CV constraint:

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