## Task 1
|

|
|
|
|||
|

Write a simple program, where you create one child process.

Parent proces should write a "I am a parent" message, while your child process should write "I am a child".

man 2 fork

|||
|
|

## Task 2

|||
|
|
|
|||
|
|
Please extend last program - make both processes display their process ID (PID) and their parent's PID.

|||
|
|
man 2 getpid

man 2 getppid

## Task 3
|
|||
|
|
|
|||
