Hoe kan ik waarden in de database (mySql) invoegen met behulp van het cpp-programma?

Probeer het als volgt:

MYSQL mysql,*connection;
MYSQL_RES result;
MYSQL_ROW row;


mysql_init(&mysql);
connection =mysql_real_connect(&mysql,"localhost","root","12356","hari",0,NULL,0);

if (connection==NULL)
{
    cout<<mysql_error(&mysql)<<endl;
}
else{
    nQueryState = mysql_query(&mysql,"insert into  userdetails values('"+nId+"','"+szName+"','"+szPassword+"','"+szQuestion+"','"+szPhone+"')");

  if (nQueryState !=0) {
    cout << mysql_error(connection) << endl;
    return 1;
  }
}

mysql_close(&mysql);
