Consider the following code snippet:

int main$()\{$ int ret; int pipe$\_$fd$[2]$; ssize$\_$t rlen, wlen; char $*$str $=$ "Hello from the other side!"; char $*$buf $=($char $*)$ malloc$(100*$ sizeof$($char$))$; if $($pipe$($pipe$\_$fd$)==-1)\{$ perror$("$Error: failed to open a pipe."$)$; $\}$ pid$\_$t pid $=$ fork$()$; switch $($pid$)\{$ case $-1$: perror$("$Error: failed to fork$()")$; case $0$:

rlen $=$ read$($pipe$\_$fd$[0],$ buf, $100)$; printf$("[$ Child $|$ fd: $\%$d$]$ read $\%$s$,$ len: $\%$ld

$",$ pipe$\_$fd$[0],$ buf, rlen$)$; close$($pipe$\_$fd$[0])$; break; default: wlen $=$ write$($pipe$\_$fd$[1],$ str$,$ strlen$($str$)+1)$; printf$("[$Parent $|$ fd: $\%$d$]$ write $\%$s$,$ len: $\%$ld

$",$ pipe$\_$fd$[1],$ str$,$ wlen$)$; close$($pipe$\_$fd$[1])$; break; $\}$ return $0$; $\}$

Which of the following statements is$/$are true $($choose all that apply$)?$

Group of answer choices

This code will raise an error as pipe$\_$fd$[0]$ is the write file descriptor and pipe$\_$fd$[1]$ is read file descriptor. The code uses incorrect file descriptors for reading$/$writing$.$

This code runs without any error.

The child process will wait on read$()$ until data is available from the pipe.

This code will raise an error as the parent process closes the write file descriptor as soon as it writes $$Hello from the other side!$$ to the pipe.

Even if the parent process closes the write file descriptor child process will have access to the read file descriptor as long as there is data in the pipe that hasn't been read.$$
