Write four
C or C++ program Q1-Q4 described
below.
Each
program creates two children processes: The first is “Male” and the 2nd
is “Female”
The two
children communicate using the following IPC methods:
Q1:
shared memory
Q2: sockets
Q3: pipe
Q4: shared file
ü The male process writes the following
message to the female process:
How are you my sister?
ü The female process reads this message,
prints it to the tty, replies to the male process with
the message, and
sleeps 1 seconds then exits.
I am fine my
brother, thanks!
The male
process reads this reply and sleeps 2 seconds then exits.
ü The parent waits until both children
exits. It prints to the tty a message whenever a
child exits:
Son(or Daughter) Exited.
