Answer #1

fork() creates a new process termed as child process. This child process runs simultaneously with parent process (process from which the fork is called). In the program, the first line creates a child process and the second line creates two child processes. This is because the parent and child process continuously executes the second fork(). Two outputs are possible here as we cannot predict to which process the OS gives control.

#include <stdio.h> 2 #include <sys/types.h> 4 int main() int pidi fork(); int pid2 fork(); 8 if(pidl && pid2) 9 printf(A 10

OUTPUT 1

program finished with exit code 0 Press ENTER to exit console

OUTPUT 2

ABBB . .Program finished with exit code 0 Press ENTER to exit console-

The possible strings this program generate as output are given below:

ABBBB

    Q1) Including the initial parent process, how many processes are created by the program shown in Figure 1? Give an explanation for your answer. You can include an output statement to test and run the program.

    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()...

    Round 2: pipeline.cThis program takes the same input as sequence.c, but executes the commands as a pipeline, where the output of each command is piped to the input of the next command in line. The input of the first command, and the output of the final command, should not be altered. For example, if the file "cmdpipe" contains the linesls -s1sort -ntail -n 5then running./pipeline < cmdpipeshould output the 5 largest files in the current directory, in order of size.Suggested approach: set...

    Round 1: sequence.c This program should read and execute a list of commands from stdin. Each command and its arguments (if any) will appear on a separate line. For example, if the file "cmdfile" contains the lines: whoami cal 4 2019 echo The time is: date then running 1 /sequence< cmdfile should output your username, a calendar of the month of April, the string "The time is:", and the current date/time, to standard output. Suggested approach: first, make sure you...
