C++ Assignment Setup Part 1: Working With Process IDs Modify the getProcessID() function in the file named Processes.cpp The function must find and store the process's own process id The function must return the process id to the calling program. Note that the function currently returns a default value of -1.Hint: search for “process id” in the “System Calls” section of the Linux manual. Part 2: Working With Multiple Processes Modify the createNewProcess() function in the file named Processes.cpp as follows: The child process must print the message I am a child process! The child process must then return a string with the message I am bored of my parent, switching programs now The parent process must print the message I just became a parent! The parent process must then wait until the child process terminates, at which point it must return a string with the message My child process just terminated! and then terminate itself. Hint: search for “wait for process” in…
Unix assignment Purpose: The purpose of this assignment is to use various concepts of the C Shell. 0. Change your default login shell to the C Shell. 1. Create a .cshrc file in your home directory that will do the following: * Create the alias (lsall) that will do all of the following: display the date, and a recursive long list of all files in a directory. * Create the alias (whoson) that will display the date and a sorted list of users logged in. * Declare the LOCAL variable that controls the size of your history list to the value 200. * Declare the shell variable that will cause the C Shell to send a message to your terminal whenever one of your background commands complete. 2. Create a .login file in your home directory to do the following. * Declare the GLOBAL Terminal Type variable to the value vt100. Display the value of the variable. Logout and log back in to make sure your .cshrc and .login files are automatically executed. Create a lab8.scr…

Topics: Functions, Files Read and write, DictionarySuppose you are given an input file of a document that only contains English words, spaces, commas(always followed with one space) and periods (always followed with one space). Your task is to readthe file, count the word frequency by ignoring the letter case, output the frequently used words (i.e.,the words occurred more than once) and the most frequently used word among all of them.Lab Scenario: Count the word in a document1. The program reads from an already provided input file: “document.txt”, which containsseveral paragraphs separated by an empty line.2. You will perform the file open operation. And then perform the read operation with your choice ofread functions and read the content of the file.3. Once you are done reading, start processing the contents of the file using a dictionary where thekey would be the word in lowercase and the corresponding values would be word frequency whichwill be the number of occurrences in the…
Filename for submission: atm.py Consider the software that runs in an Automated Teller Machine (ATM) machine. One task that must be able to be performed is to determine the type (denomination) of currency and the numbers of bills (aka "banknotes" for those of you not from North America) for each type dispensed. A requirement is that our ATM use the fewest number of bills that it can to dispense the specified amount of money. It only dispenses fifties, twenties, tens, fives, and ones. Design and implement program that writes out what bills would be dispensed if this machine existed for the amount of money that was asked for by the user. Note: This assignment requires you to pay particular attention to your output formatting. Be precise in your spelling and spacing. Match the textual prompts exactly as you see in the example below in order to pass our automated testing suite. You may copy the prompts given here to use in your code: Welcome to PDQ Bank! Amount to withdraw? $ Cha-ching!…
A file has r = 20, 000 STUDENT records of fixed length. Each record has the following fields: NAME (30 bytes), SSN (9 bytes), ADRESS(40 bytes), PHONE(9 bytes), BIRTHDATE (8 bytes), SEX(1 byte), CLASSCODE( 4 bytes, integer) MAJORDEPTCODE(4 bytes), MINORDEPTCODE(4 bytes), and DEGREEPROGRAM( 3 bytes). An additional byte is used as a deletion marker. Block size B = 512 bytes. a) Calculate the blocking factor bfr (=floor(B/R), where R is the record size) and number of file blocks b, assuming unspanned organization (a record can’t be split across blocks). b) Suppose only 80% of the STUDENT records have a value for PHONE, 85% for MAJORDEPTCODE, 15% for MINORDEPTCODE, and 90% for DEGREEPROGRAM. We use a variable-length record file. Each record has a 1-byte field type for each field in the record, plus the 1-byte deletion marker and a 1-byte end-of-record marker. Suppose that we use a spanned record organization, where each block has a 5-byte pointer to the next block (this space is not used…

Q1: Write a Python program that prompt user to enter at least five entries: 1. Each entry requires two entities: Name (first, last) and Final Score (between 0 and 100) 2. saves the values in a text file 3. calculates the average for Final Score for all the entries written into the file 4. reads that text file and displays its contents on the command prompt including the score average. Write a Python program that prompts the user to search for a string( first and last name) from the file created in Q1. The program displays the name and the final score for that entry if that name was in the file.
If a file contains an index directory that allows for random access, what does it mean?
