I'm new into mysql and has been encountering huge problem in
connecting to the database from the c application. Error message is:
Failed to connect to database: Error:
Client does not support authentication protocol requested by server;
consider upgrading MySQL client
Press any key to continue

here is the application:
#include "stdio.h "=20
#include "winsock.h"=20
#include "iostream.h "

#include "mysql.h"

int main()
{=20

MYSQL mysql;=20
MYSQL_ROW row;=20
MYSQL_RES *result;=20

unsigned int num_fields;=20
unsigned int i;=20
int num =3D 0;
int iRetValue =3D 0;

mysql_init(&mysql);=20
//printf("%s",&mysql );

if (!mysql_real_connect(&mysql,"localhost","sampadm", "secret","sampdb",3306=
,
NULL,0))
{=20
fprintf(stderr, "Failed to connect to database: Error: \n%s\n",=20
mysql_error(&mysql));=20
}=20
else=20
{=20
printf("SUCCESS\n");
iRetValue =3D mysql_query(&mysql, "SELECT * FROM user");

if( iRetValue !=3D 0 )
{
printf("Query Not Executed Properly.Please Check The Syntax.\n");
}
//here goes the error message )=20
else
{=20
result =3D mysql_store_result(&mysql);

num =3D mysql_field_count(&mysql);
printf("Number Of Rows :%d\n",num );

num_fields =3D mysql_num_fields( result);
printf("Number Of Coloumns :%d\n",num_fields );

while ((row =3D mysql_fetch_row(result)))=20
{=20
unsigned long *lengths;=20
lengths =3D mysql_fetch_lengths(result);=20

for(i =3D 0; i < num_fields; i++)=20
{=20
printf("[%.*s] \t", (int) lengths[i], row[i] ? row[i] : "NULL");=20
}=20
printf("\n");=20
}=20
}=20
}
}=20

I would appreciate if you guys can help. thanks.
