MySQL Can't get the output...
I wrote a code like this.......

#include <iostream>
#include <stdio.h>
#include <mysql.h>
#include <string.h>
#include <stdlib.h>

using namespace std;

#include "Connection.h"


int main()
{
char *Host = (char *)"localhost";
char *Database =(char *)"sachin";
char *UserId =(char *)"root";
char *Password =NULL;
Result *result;
char *query;
Connection DbConnection(Host, Database, UserId, Password);
query="select * from the test"; // test is my database
result = DbConnection.Query(query); // perform the required database operation..


return 0;
}

Connection is the class & have connect function that just took the 4 arguments & establishes the connection to the mysql server ...Also Query is the function defined in connection class.

I m getting output as -
$g++ -c -I/usr/include/mysql Main.cpp
$ g++ -o Main Main.o -L/usr/lib/mysql -lmysqlclient
$./Main
terminate called after throwing an instance of 'char const*'
Aborted

I don't know why i m getting this output. I think it is related to the library.......

Can any one help me......
