The above C program creates a child process using the system call fork $().$ If the child

process is created successfully, $(1)$ what will be the output? $($Assume the pid of the

newly$-$created child process is $1000)(2)$ How many lines will the program $($both

parent and child processes$)$ print? If your answer is one line, then skip the next

question. Otherwise, continue. $(3)$ If we want to print the message line ONLY from

the parent process $($not the child process$),$ how will you modify the program?
