Failed to connect to MYQL Server

Hi,
I am using UBUNTU Distro For Mysql Client and Trying to connect to Mysql Server on Debain Distro.And on client side written a C API for row access of table location.

Code:

   1. #include <stdio.h>  
   2. #include <stdlib.h>  
   3. #include "mysql.h"  
   4.    
   5. int main()  
   6. {  
   7.    MYSQL *conn;  
   8.    MYSQL_RES *res;  
   9.    MYSQL_ROW row;  
  10.    
  11.    char *server = "amitsaini";  
  12.    char *user = "root";  
  13.    char *password = "rrr777"; /*set me first */  
  14.    char *database = "location";  
  15.    
  16.    conn = mysql_init(NULL);  
  17.    /* Connect to database */  
  18.    if (!mysql_real_connect(conn, server,  
  19.          user, password, database, 0, NULL, 0)) {  
  20.       fprintf(stderr, "%s\n", mysql_error(conn));  
  21.       exit(1);  
  22.    }  
  23.    
  24.    /* send SQL query */  
  25.    if (mysql_query(conn, "show tables")) {  
  26.       fprintf(stderr, "%s\n", mysql_error(conn));  
  27.       exit(1);  
  28.    }  
  29.    
  30.    res = mysql_use_result(conn);  
  31.    
  32.    /* output table name */  
  33.    printf("MySQL Tables in mysql database:\n");  
  34.    while ((row = mysql_fetch_row(res)) != NULL)  
  35.       printf("%s \n", row[0]);  
  36.    
  37.    /* close connection */  
  38.    mysql_free_result(res);  
  39.    mysql_close(conn);  
  40. }
