- The simulator will consists of following classes: (i) Process: The data members of this class should store process id, arrival time in the ready queue, CPU burst time, completion time, turn around time, waiting time, and response time. The member functions of this class should assign values to the data members and print them. A constructor should also be used. (ii) Process Creator: This class will create an array of processes and assign a random arrival time and burst time to each process. Data members, constructor and member functions can be written accordingly. (iii) Scheduler: This class will implement the scheduling algorithm. The class will maintain a ready queue of infinite capacity (i.e., any number of processes can be accommodated in the queue). The ready queue should be implemented using the min-Heap data structure where the highest priority process will be the root. The priority of the process will depend on the scheduling algorithm. The ready queue (i.e., min-heap) should be…For this HW assignment, you will demonstrate that you can write data files. Python program will you write data to a file. The specific requirements for each program are:1) The first program will use the code that is contained in HW12-WriteStart.py to create thedata to be written out. Please feel free to examine the code provide but do not modify thecode. Place your code below the comment that says to place your code below this line. Thecode you should add should do the following:a. Specify a default file name to use for the output file.b. Check to see if the file already exists. If it does already exist, ask the user if it is okayto overwrite the file—be sure and tell them the file name. For an extra challenge andbonus points, prompt the user to enter a new file name.c. The data created by the initial code in HW12-WriteStart.py creates a list named Rowsthat contains rows of data. Each element of Rows is another list that contains a nameand some quiz scores. You are to write each row of…In python, rite a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit... Otherwise, if the pathname refers to a directory, the function is applied to each name in the directory, like so: Directory name: directory_path File name: file_path1 Lorem ipsum dolor sit amet... File name: file_path2 Lorem ipsum dolor sit amet... ... Test this function in a new program.
- 3. The C code is given (see Table3) Table3 if ((fp = fopen(filename, r )) == NULL) { printf("Error. Cannot read from file %s. Exit\n", filename); exit( 1 ); } while (fgets(line, sizeof line, fp) != NULL) { printf("Successfully copied"); } fclose(fp); Based on the above program, answer the following: a) Write down how many systems call this program invokes? b) Explain what type of system call it is.Using the Seek() Method in C#In the next steps, you use the Seek() method to reposition a file pointer so you canaccess a file from any location. The user will be prompted to enter a number representinga starting point to list the names in the Names.txt file. Names from that pointforward will be listed, and then the user will be prompted for another selection.1. Start a new program named AccessSomeNames that demonstrates howto access requested names from the Names.txt file you created in theCreateNameFile application.Searching a Sequential Text File using System;using static System.Console;using System.IO;class AccessSomeNames{static void Main(){FileStream file = new FileStream("Names.txt",FileMode.Open, FileAccess.Read);StreamReader reader = new StreamReader(file);In this laboratory work, you are expected to write a c# console application to make someoperations about the customers. Operations and required featurest that you need to cover inyour program are following:• Add: This function adds a new person to json file. You need to get inputs from userand adds the new one into json file.• Display: This function displays all people in your json file.• Search: This function let you search with the user id.• Create Password: This function will create a random password for the user and usermay choose the length of the password. Password may include numbers andcharacters.• Exceptions: You need to handle exceptions as well. You should at least handle 3 ofexceptional cases. For the case that file can not be found, It is mandatory to catch theexception.
- Write C++ Program that does the following: •Instead of reading data from the user, I will give you a file, grades.txt (look in ~cthorpe/public/141) •The format of the file is: –First line: number of records –Subsequent lines: Last name on a line by itself First name and three homework grades •Read function: parameters are –An instream, passed by reference, from which to read the data –Fields for firstname, lastname, grade1, grade2, grade 3 •The read function should read in the data from the instream. It is a void function •What types are the parameters? How will you pass them? •Write function: parameters are –Firstname, lastname, grade1, grade2, grade3, average grade, letter grade –What types are those parameters? Do you need to pass them by reference? •The write function will write the data to the screen formatted neatly –Which formatting instructions will you need to use? Overall program flow: •Open the file in the main program. •Read in the number of records •For…• Create a Phonebook Program based in C Programming Language. The program will get the First Name, Last Name, Contact Number, and E-mail Address. • The program can Add, Update, Read, and Delete the data of the Phonebook. The Details can be searched by either using the Last Name, First Name, Contact Number and E-mail Address.Create a program in C language for reading and writing student records. Submit all necessary source codes and files to run this program (it is recommended to compress all files and submit a single file). First create text file "student_records.txt". The file should look like: Name Surname Quiz 1 Quiz 2 Quiz 3 Ada Lovelace 93 88 97 Babbage Turing Нopper Charles 26 80 70 Alan 74 85 92 Grace 99 87 100 a. Read the file contents and load them into an array of Record structs. b. The record struct has the member variables: o char array name o char array surname o int quiz_1 o int quiz_2 o int quiz_3 c. Write a function that calculates a students quiz average. The function takes a Record struct and returns a double. d. Create two new records for students inside your main program. e. Create a new text file with the new records to a a file called "student_records_new.txt"
- Invalid indexes in slicing expressions can produce an ‘out of bound’ exception.True or FlaseWrite C++ Program that does the following: •Instead of reading data from the user, create a txt file that will be imported into the code •The format of the file is: –First line: number of records –Subsequent lines: Last name on a line by itself First name and three homework grades •Read function: parameters are –An instream, passed by reference, from which to read the data –Fields for firstname, lastname, grade1, grade2, grade 3 •The read function should read in the data from the instream.

Overall program flow: •Open the file in the main program. •Read in the number of records •For each record,…The default library method int fseek(FILE *fp, long offset, int origin) is similar to Iseek except that the return value is an int status rather than a location, and fp is a file reference rather than a file descriptor. Compose fseek. Ensure that the caching used for the other library functions and your fseek are correctly coordinated.
