How to use Command line argument in GCC compiler

[Sender.c]

#include<stdio.h>
#include<fcntl.h>
#include<string.h>
void main(int argc, char *args[])
{
int i,count=0,len,j=0,pid;
char frame[50],data[50];
        len=strlen(args[1])-8;

system("clear");
system(">pipe");
pid=open("pipe",O_WRONLY);

printf("len : %d",len);
printf("%s",data);

for(i=0; i<len; i++)
{
data[i]=args[1][8+i];
}
data[i]='\0';
printf("data %s",data);

frame[j]=len+48;
for(i=0; i<len; i++)
{
j++;
frame[j]=data[i];
}
j++;
frame[j]='\0';
printf(" Sent to frame :%s",frame);
write(pid,&frame,sizeof(frame));
}

[Receiver.c]

#include<stdio.h>

#include<fcntl.h>

#include<string.h>

void main()

{

int i,count=0,len,j=0,pid;

char frame[50],data[50];

        system("clear");

pid=open("pipe",O_RDONLY);

read(pid,&frame,sizeof(frame));

printf("%s",frame);

len=strlen(frame);

for(i=0; i<len; i++)

{

data[i]=frame[i+1];

}

data[i]='\0';

printf("data %s",data);

printf("\n receive to frame :%s",data);

Mysql java connectivity

hi Friends here are the steps to connect java with mysql database

step 1: download mysql jdbc connector from here

step 2: on your c: drive find "mysql" directory and copy above connector file in "mysql/lib" dirctory.

step 3: right click on mycomputer->properties->advance-system-setting->Environment_variable

step 4: add new variable and set 

VARIABLE NAME=CLASSPATH

VARIABLE VALUE=;C:/<YOUR DIRECTORYs>/mysql/lib/mysql-connector-java-5.1.2.jar;

step 5: click on ok->ok->ok

step 6: write following code

import java.sql.*;
import java.io.*;
public class connect
{
 /*
 * master-gtu.blogspot.com
 * Pankaj Sharma(8460479175)
 */
 public static void main(String args[])
 {
  try
  {
  Class.forName("com.mysql.jdbc.Driver");
  Connection con=DriverManager.getConnection("jdbc:mysql://localhost/neelkanth","root","");
// here neelkanth is database name and root is username and password is blank
  //System.out.println("Connected to DATABASE");
  Statement stmt = con.createStatement();
  ResultSet rs=stmt.executeQuery("select * from notice");
  while(rs.next())
  {
   System.out.println(rs.getString(3));
  }
  con.close();
  }
  catch(Exception e)
  {
   System.out.println(e.toString());
  }
 }
}

step 7: Wao connectivity success... """""""""Happy Coding"""""""""""
