why isnt my code working? here is the assignment.

#include

int main$()$

$\{$

pid$\_$t pid;

char $*$message;

int n;

printf$("$fork program starting

$")$;

pid $=$ fork$()$;

switch$($pid$)$

$\{$

case $-1$:

perror$("$fork failed"$)$;

exit$(1)$;

case $0$:

message $=$ "This is the child";

n $=5$;

break;

default:

message $=$ "This is the parent";

n $=3$;

break;

$\}$

for$($; n $>0$; n$--)\{$

puts$($message$)$;

sleep$(1)$;

$\}$

exit$(0)$;

$\}$

Zombie Process

When a child process terminates, an association with its parent survives until the parent in turn either:

calls wait$()$ orterminates normally

The child process entry in the process table is therefore not freed up immediately. Although no longer active, the child process is still in the system because the exit code needs to be stored in case the parent subsequently calls wait$().$ The child becomes what is known as defunct, or a zombie process.

Orphan Process

If a parent process did not invoke wait $()$ and instead terminated, its child processes remain as orphan processes

Programming:

To compile:

gcc fork$1.$c $-$o fork$1$

To run:

$./$fork$1$

Compile and execute fork$1.$c program. The original process $($the parent$)$ finishes before the child has printed all of its messages, so the next shell prompt appears mixed in with the output. Does the child become an orphan? Why or why not?

Convert the fork$1.$c program t o a zombie process. $($Hint: change the number of messages. If the child prints fewer messages than the patent, child will finish first and will exist as a zombie until the parent has finished.$)$

and this is the code i inputed
