Hello,
can you help me to write this program?

Write a program that create 2 processes and 1 named pipe,where 1st child calculate 1st prime number, send it to pipe. 2nd process reads it from pipe and calculates next prime number and send it back to pipe.Controle synchronization with a semaphore.
Example of execution
Process 1527 prime number is 1
Process 1528 prime number is 3
Process 1527 prime number is 5
Etc…

N.B:while 1st process calculates ,2nd process should be blocked by semaphore
thanks
