Adding 2 numbers in a Multiclient environment
|
Can't Post
|
|
Hi,
I want to add two numbers. I have multiple clients but one server. The problem is that if 'client 1' sends 1 and 'client 2' sends 3, server prints 4. I want that server should wait for 2 numbers from each client and then print the sum. I have used 'fork' but its not solving the problem.
Server Code
#!C:/Perl64/bin/perl.exe
use IO::Socket::INET;
$server=IO::Socket::INET->new(LocalPort=>'5465',Proto=>'UDP');
$pid = fork ( );
if ($pid == 0) {
while(1) {
$server->recv($num1,1024);
print("\nnum1=", $num1);
$server->recv($num2,1024);
print("\nnum2=", $num2);
print ("\nSum=" , $num1 + $num2 + "\n");
$|++;
}
}
Client Code
#!C:/Perl64/bin/perl.exe
use IO::Socket::INET;
while(1) {
$client=IO::Socket::INET->new(PeerPort=>'5465',Proto=>'UDP', PeerAddr=>'127.0.0.1');
print("Enter the first number\n");
$Num1=<STDIN>;
$client->send($Num1);
print("Enter the second number\n");
$Num1=<STDIN>;
$client->send($Num1);
}
Please guide me.
Zulfi.
