All the files have been commented for your ease. Furthermore you may also add further comments if you may.

How to run:

1: Compile s1, s2, s4, c and proxy.cpp.

2: In separate terminals, run the executables of all server files in this order s1 -> s2 -> s4 -> proxy.

3: Again in separate terminals, run the client executable. For multiple clients, run the same executable in different terminals.

4: Select whatever you wish the clients to do.

Doesn't require anything more than a C++ compiler and a shell
