Write the Windows and Linux Communication Programs with Socket

Socket is very familiar with everyone, I am no longer here. Cut the topic directly. The program is divided into two parts, the Server side and the Client side (no one know). Where the Server terminal uses a Windows platform, the Linux platform is of course a client end. Here is the Server-end program: / ******************************************* / / * IT WORKED AS Server Under Windows Platform * // * Written by mlsx 1998-2-7 * // ****************************************************** ** /
