database connection checking in c++ program - c++

Question

I am trying to connect a database with the c++ program using OCILIB interface.
my program is:-
#include "ocilib.h"
int main(int argc, char *args[])
{
OCI_Connection *cn;
if (!OCI_Initialize(NULL, NULL, OCI_ENV_DEFAULT))
cout << "connection failed";
cn = OCI_ConnectionCreate("db", "usr", "pwd", OCI_SESSION_DEFAULT);
if (cn != NULL)
{
cout <<OCI_GetVersionServer(cn);
cout <<"Server major version : %i\n"<< OCI_GetServerMajorVersion(cn);
cout <<"Server minor version : %i\n"<<OCI_GetServerMinorVersion(cn);
cout <<"Server revision version : %i\n"<< OCI_GetServerRevisionVersion(cn);
cout <<"Connection version : %i\n"<< OCI_GetVersionConnection(cn);
OCI_ConnectionFree(cn);
}
OCI_Cleanup();
}
this code running in MSVisualstudio2015, I downloaded all OCI packages and set according to my environment..
i put linker path and additional include header files in project properties.
but when i building the application it shows.

You need to copy ociliba.dll from the ocilib archive (under lib32|64 folder) to the folder where your executable is generated.
