I am trying to compile code below in Microsoft visual c++.
#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <fstream>

    using std::ifstream;

    using std::ofstream;

#include <iostream>

    using std::ios;

    using std::cout;

    using std::endl;


/* DB2 ODBC Header */
#include <sqlenv.h>
#include <sqlca.h>


int main ()
{
    char dbname[15] ;
    char user[128 + 1] ;
    char pswd[15] ;

    strcpy (dbname, "DB2HNB1");
    strcpy (user, "STORBIT");
    strcpy (pswd, "TOUCHP2");
    EXEC SQL CONNECT TO :dbname USER :user USING :pswd;
    if (SQLCODE != 0) {
        printf ("\n *** Error ***\n");
        exit (0);
    }
    else {
        printf ("\n Successful connection to '%s' db using C
        embedded static SQL\n",dbname);
    }

    return 0;

}

I can not figure out why I am getting this error:
