پیاده سازی برنامه چت بین دو کامپیوتر بصورت (/) با ویژوال سی پلاس پلاس  

در این برنامه ابتدا قسمت سرور را در حالت listen (گوش دادن) قرار می دهیم و سپس کلاینت را نیز اجرا میکنیم و از طریق پورتی که در این برنامه تعریف کرده ایم ارتباط برقرار می شود و سپس می توان به تبادل پیام بین دو سیستم پرداخت .  

همراه با فایلهای EXE , CPP و سایر فایلهای مورد نیاز
