[C++] IPC using named pipes

Write two programs, Producer and Consumer. Run the producer program multiple times and the consumer program multiple times in separate terminal windows, all simultaneously.

The first producer process should create a named pipe (FIFO) and write data values 101, 102, 103, etc. to it. The second producer process should write data values 201, 202, 203, etc. to the pipe. Other producer processes should write similar data values. Each process should also write the data values to its standard output. Each consumer process should read the data values from the pipe and write each value to its standard output.

The producer program should take two command-line parameters, an id and the number of data values to write to the pipe. The producer process with id 1 should first remove the named pipe (unlink) in case its left over from a previous run and then create a new pipe (mkfifo). The other producer processes should simply write to the pipe that process 1 created. After each producer process has written all its data values, it should write a done message to its standard output and then terminate normally.

For example, you can start three producer processes with these commands, each in a separate terminal window: ./producer 1 50

./producer 2 60

./producer 3 70

The consumer program should take an id as its single command-line parameter. After all the producer processes have completed writing and there are no more data values in the pipe, each consumer process should write a done message to its standard output and then terminate normally. For example, you can start two consumer processes with these commands, each in a separate terminal window:

./consumer 1

./consumer 2
