C + + compilation error cannot has Cv-qualifier

C + + compilation error cannot has cv-qualifier

in the C + + in CV means Const and the volatile two x keyword. There are two cases where you cannot use CV -qualification.

a non-member function cannot contain CV qualification, i.e. Const and the volatile Limited

#include <iostream>

using namespace Std;

Double Getarea () const

{

return 0.0;

}

Double Getvolume ()const

{

return 0.0;

}

int main (int arg,char *argv[])

{

cout<< getarea () << Endl;

cout<< getvolume () << Endl;

return 0;

}

compilation generates an error, meaning that a non-member function cannot have CV Qualifier, CV There are two qualifiers: Const and the volatile , here refers to Const .

second, static member functions cannot have CV qualification, i.e. Const and the volatile Limited.

header File static_cpp.h

#ifndef __static_h

#define __static_h

Class CStatic

{

Private:

static int static_value;

Public:

static int get_static_value () const;

};

#endif

source File staitc_cpp.cpp

#include "Static_cpp.h"

Intcstatic::get_static_value () const

{

return static_value;

}

in the main.cpp in

#include "Static_cpp.h"

#include <iostream>

using namespace Std;

int cstatic::static_value= 1;

int main (int argc,char*argv[])

{

cout<< cstatic::get_static_value ( ) <<endl;

return0;

}

compile error, meaning: Static member function, cannot have CV Qualifier, in C + + in CV qualifier refers to Const and the volatile , here refers to Const .
