Methodz i found an example of winsock programming on the net.I just wanted to verify from you .The portion of code Win Connect is the client software (which will go inside my my laptop)and the sceond portion Win Listen is the server software(which will go inside my fathers laptop). Is there anyway i can execute the both portion of code in my computer. This is a quote from the tutorial that i am reading.the line marked in red has made me ask you this question.

In the part 1, we looked at initializing the library, creating sockets, making our own connections, and terminating the
library and our socket handle(s). Now it's time to look at all of this, but instead of connecting, we will be listening for
our own connections instead. To do so, we need to bind our socket to a defined port, then use the listen() function to wait
for connections. To test whether or not our program succeeded, we can use the command prompt. netstat -ano (o for PID, n for
numerical output, and a for displaying listening ports/active connections) does the trick because we can refer to the PID of
our application using the task manager, then check whether or not the PID shows up in the output, along with the defined
port.
