Chapter 8, Problem 8.17HW

Program Plan Intro

Given code:

//Include necessary header files

#include <stdio.h>

#include "csapp.h"

//Define a main function

int main()

{

//Variable declaration

int status;

pid_t pid;

//Print the statement

printf("Hello\n");

//Call the method fork() and assign it to the variable pid

pid = fork();

//Print the statement

printf("%d\n",!pid);

//Check, pid is not equal to zero

if (pid != 0)

{

    //True, check the condition

    if (waitpid(-1, &status, 0) > 0)

     {

       //True, check the condition

      if (WIFEXITED(status) != 0)

        //True, print the statement

        printf("%d\n" , WEXITSTATUS(status));

    }

}

//Otherwise, print the statement

printf("Bye\n");

//Exit

exit(2);

Task 2The cells of the battery are treated using a programmable lathe machine. The machine has 15programs that are able to control its speed. Program 1 has 11 ( N( 1) = 11) different speeds thatcan vary from 100 revolution per minute (rev/min) to 1100 (rev/min). Program 2 has 13 ( N(2) =13) speeds that can vary from 110 rev/min to 1430 rev/min ( X1(1) = 100, X2(1)=110,and so on). The number of speeds of the higher programs increases using geometric progressionand the speeds within the same program follow the same pattern of the common differenceachieved in program 1 and 2 and increase using arithmetic progression.1. Determine the general formulas of the speeds of the programs and the number ofspeeds of the programs.2. Construct a sequence using the final speed of each program. Is there any relationbetween these speeds?3. Determine the number of speeds of program 10, and the value of speed number 7within program 10.4. Determine the total number of speeds that can be produced.5.…

Write a computer program using any arbitrary programming language (MATLAB, C++, C#, Python,.) to calculate economic load dispatch (ELD) using first order gradient method. Note that all parameters and variables should be defined inside the program (at tirst limes) such that units' charactenistics and demand can be changed easily. Neglect grid losses.
