I am trying to have one end(user) send messages and other end(server) reading them and just writing them down. The user.cpp is working fine it keeps asking you to enter a message after establishing a connection.
The server.cpp works fine too to the point of establishing connection (it tells the connection is made once you run user.exe / user.o) but it won't write the received message to console. i am sure it is receiving the messages because it would've generated an error other wise because of the line
if(n<0)std::cout<<"Fail to read\n"; But it's not, it just keeps wiating and wiating and prints no message ;/ i don't have C background so I could've fucked up somewhere
