C$++$ Will introduce inter process communication and redirection. We will use pipe$()$ and dup$()/$dup$2().$

The assignment is to pipe output from the child to the parent. You can choose whichever output you like, but the standard "Hello World" would be sufficient. Your program should:

Check to verify the fork was created

Prompt for arguments from the user. There are two arguments that you will need to create $(-$o and $-$b$)$; however, they are optional. To prove that the fork works, your program should print "Hello World", in either the standard terminal, the output.txt file, or both. $($

If no arguments are given, standard output to the terminal

Use one of the optional arguments $(-$o or $-$b$)$ for an extra $20\%$ on your A$3!$

Execute the command without any errors

Pipe the output from the child to the parent process

Successfully redirect the parent process output to the correct location

If you send output to the output.txt$,$ file:

If output.txt does not exist, then your application should create it$.$

If output.txt does exist, then the file should be truncated and over written.about the output.txt would problaby need to be created. The output should be this:

Fork created successfully

Hello world
