What gets inherited by child processes $($lastnameTestInheritance$1,2.$c$)$:

In Linux, a newly created process inherits many attributes from its parent, including the parent's

variables and its open file descriptors. Follow the steps below to test what attributes are

inherited by a child process:

Test inheritance of variables:

Parent process:

Define a variable $n=5.$

Fork the program.

Print $n.$

Wait for the child process.

Print $n.$

Child process:

Sleep for $5$ seconds.

Print $n.$

Increase $n$ by one.

Print $n.$

Start each print in the parent process with $"p".$ Start each print in the child process

with $"[$c$]".$

a$.$ In what order do the four prints occur? $($For example, "child then parent then parent

then..."$)$ Why?

b$.$ What values are printed by the parent? Why? What values are printed by the child?

Why?

Test inheritance of open file descriptors:

Parent process:

Child process:

Open a file to write.

Fork the program.

Write "parent" to the file.

Close the file.

Write "child" to the file.

Close the file.

c$.$ Do both processes write to the file? Why or why not?

d$.$ Run the program multiple times. Which processes print? in what order? and why?
