Write a C/C++ program that performs the tasks described below. The program should fork one process.  Have the new process execve the program named /bin/sed.  Use dup2 (or dup) with a pipe to establish a way for the original process to capture stdout from sed.  The program will accept command-line arguments that it passes along to sed via execve. Any valid sed arguments may be used during testing. Sample executions are given below. Be sure to have this:     alarm(90); as the first executable line in *BOTH* processes, which means you will need to do it in at least one of the processes after the fork.

Question

Write a C/C++ program that performs the tasks described below.

The program should fork one process.  Have the new process execve the
program named /bin/sed.  Use dup2 (or dup) with a pipe to establish a way
for the original process to capture stdout from sed.  The program will
accept command-line arguments that it passes along to sed via execve.
Any valid sed arguments may be used during testing.
Sample executions are given below.

Be sure to have this:

    alarm(90);

as the first executable line in *BOTH* processes, which means you will
need to do it in at least one of the processes after the fork.


Tests will be done by typing commands like this:

   ./p4 's/p/Z/g' TEMPIN

The original process should capture stdout from sed and then print EACH line
prefixed by:
    SED:
For correctness, it is important that EACH line have the prefix.

For example, suppose that TEMPIN contains these lines:
    harry potter powerful wizard
    hermione played chess
    snape taught many pupils

If the program is run as above:
   ./p4 's/p/Z/g' TEMPIN
then it would print:
    SED: harry Zotter Zowerful wizard
    SED: hermione Zlayed chess
    SED: snaZe taught many ZuZils
