How it is possible for the child process to have access to the same pipe which was created and later is used by the parent
Homework Answers
Pipe is one-way communication that means only one process can write at a time and other process can read from file no other process can write when 1 process is writing
pipe is a special file with no extention and it follows FIFO method to read write data.
sometimes pipe is also called "shared communication
channel"
in which all the process do share thier data from the one end to in
and from another end to out.
pipe can be created by child or by parent and it can be created
only once which ever process execute first that will create a pipe
using mkfifo() system call if the pipe is already exist then it
will not create again but will check the status and share it to
exchange data.
if you have any doubt then please ask me without any hesitation in the comment section below , if you like my answer then please thumbs up for the answer , before giving thumbs down please discuss the question it may possible that we may understand the question different way and we can edit and change the answers if you argue, thanks :)

Write code that forks into two processes: a parent process, and a child process. Same as the Regular version, except that your code must also be able to handle negative integers input from the command-line. If I call your code this way: a03 -3 5 -7 The parent process should print out: Assignment 3 sum = -5 The sums produced from the test input I use will be in the range [-128 .. 127] -------------------------------------------------------------------------------------------------------------------- // Numbers from...

Write code that forks into two processes: a parent process, and a child process. Your code will be called with command-line arguments consisting of negative integers. Do not worry about bad command-line arguments such as "xyz". Your code will not be tested in this way. The parent process will take the arguments to main(), convert them into ints by calling atoi(), and send those ints one at a time to the child process through a pipe (one call to write()...

Using either a UNIX or a Linux system, write a C program that forks a child process that ultimately becomes a zombie process. Process states can be obtained from the command: ps -l The process states are shown below the S column; processes with a state of Z are zombies. The process identifier (pid) of the child process is listed in the PID column, and that of the parent is listed in the PPID column. Because you do not want...

10) Unlike a signal, which conveys only the occurrence of a particular event and contains no information content, a pipe can be thought of as a scratch file created by a system call. It can be used as a communications channel between concurrently running processes. The interface call to a pipe is similar to that for any file. In fact, the process reads and writes to a pipe just like any file. Unlike files, however, pipes do not represent actual...

Discuss the importance of the protected access modifier. Provide examples of when to make parent class data fields private versus protected and how a derived class can access the constructor of its parent class. Consider how the parent/child relationship is enforced with the keyword and the importance of inheritance in application development. Also, discuss how multiple inheritance is commonly used in object-oriented programming languages.
