Create a program(forkchildren.c) that will fork off two children.One child will run the “ls -l” command.The other will run “cat forkchildren.c”.The main program will wait for the children to finish and then print a note saying it is finished and then it will end.No pipe is needed for this activity, each child is separate. Provide output as example

#include <stdio.h>#include <stdlib.h>#include <unistd.h>#include…

The following program manages flight reservations for a small airlinethat has only one plane. This plane has SEATS number of seats forpassengers. This program processes ticket reservation requests from theairline’s website. The command R requests a reservation. If there is aseat available, the reservation is approved. If there are no seats, thereservation is denied. Subsequently, a passenger with a reservation canpurchase a ticket using the P command. This means that for every Pcommand, there must be a preceding R command; however, not every Rwill materialize into a purchased ticket. The program ends when the Xcommand is entered.

Question 2: B – Write a program that prompts for an input string of variable length. Once input, your program will do the following: Output the length of the string Output the first and last characters of the string Output the middle character of the string (and its position) Transpose (switch) the two halves; 2nd half starts with the middle character. Print the string out in all upper case characters Example Sessions: Please input a string :>> Firewall Program Output: String length is: 8 First char is: F Last char is: l Middle char at position 4 is: w Transpose: wallFire Upper Case: FIREWALL Please input a string :>> Program Program Output: String length is: 7 First char is: P Last char is: m Middle char at position 3 is: g Transpose: gramPro Upper Case: PROGRAM

Utilize looping to make your Python script for Functionality 2 [You should allow users to enter information for five employees at the same time, where the first employee information entry is saved in index [0] and the second entry is saved in index [1], and so on. You want to make sure to enforce the user to enter the following employee information: employeeName, employeeSSN, employeePhone, employeeEmail, employeeSalary. After the user finishes entering the last employee information, they should get a message to allow them to print specific employee information from the saved list. The user can enter values between 1 and 5, where 1 will return the employee information saved in the list index [0], 2 will return the employee information saved in the list index [1] and so on.]to run constantly. while having it run constantly Add Employee – this functionality will allow users to add new employee to the system.

(From the topic API) Write a program that calls fork(). Before calling fork(), have the main process access a variable (e.g., x) and set its value to something (e.g., 100). What value is the variable in the child process? What happens to the variable when both the child and parent change the value of x? Write out the code for your program. Run the program and show your result. What value is the variable in the child process? What happens to the variable when both the child and parent change the value of x?
