C ++ network programmingLearn how to use network protocols to use various protocols using POCOMobile platform games use non-realtime communication using HTTP for the first time due to poor wireless communication, Are increasingly being used. Most of the games are more important than other IT areas. In addition, although the use of C ++ has been reduced compared to the era of PC platform, there are still many cases where mobile platform game server is developed in C ++.C ++ is more networked than C #, Java, Python, Programming is a little more difficult. However, using an external library such as POCO can solve many of these difficulties and benefit from the high performance of using C ++. This book introduces C ++ network programming using the POCO library. . The POCO library is a library made in the 2000s, and the code is neat and well documented, making it easier to create a C ++ network program by referencing this book and the documentation on the official POCO site. In addition, the POCO library has a multitude of functions related to multithreading and databases. Please try to study.
