Dear Friend
If you so in a hurry you should search the forum first... this question has been asked before 
Anyway C++ on which operating system? the only thing you need is to be able to talk to the serial port and this is done slightly differently depending on the operating system
for example typing "c++ serial windows" into google leads to this -> Serial library for C++ - CodeProject
if you need linux or mac just type the right word into google
