implemented
# fork statement(duplicate process)
# exec function(replace process)
# signals and sigaction
# pipes
#fifo
issues faced:-
1.file descriptor was not being passed using execl() system call.
->resolved by passing address of the fd in the arguments of execl().
2.while implementing addition through a client, addition was being implemented on the ascii values……
->resolved the issue by using the integer input and type-casting it to the character.
3.while implementing fifo if large data was being passed by the large number of clients, the server wasn’t responding due to garbled data(pid and data).
