C++ 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. Take a screenshot of a sample output and upload the picture as part of your assignment submission. 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…

python function that creates and saves data in a file. the saved data represents exam grades. in the function , you will create n random numbers in the range 1-100, where n is the number of students. The function can be called as follows: createFile(filename, n) main function, in which the user inputs the file name and the number of students, then the main calls function createfile. the main should preform validation for n (should be > 0), and the filename(should end with .txt)
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!…
The Directory class has a list of names in it. You should use dynamic memory to create anarray upon instantiation. You should create a copy constructor for the directory class and anassignment operator (i.e. operator=()). You should create a function called fillDirectory whichaccepts a size for the directory and the names for it both of which should be given by the user.In main, create directory1 and fill it with information. Use the assignment operator=() to setdirectory2 equal to directory1. This is in c++
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.
PYTHON-Assume you have a file that has two columns separated by a comma. The first column contains gene accession numbers, and the second column contain their nucleotide sequence. For example: ABC123, AAGTCTTCCCTAAGCCC... KHJ456, TTCGGTCATACTATTC... NMG789, GCTACTCGATGCTA.... .... The file can contain any number of rows. Write a program that reads in this file (you can create one to test your code with, use TextEdit or Notepad) and creates a dictionary, where the keys are the accession numbers and the values are the sequences. Print out to the screen the dictionary pairs that you created.
In c++ write a code that tells a user to enter a filename and read that text file line by line.
The header record of a batch file contains totals of items in the file. Each time the file is processed, the totals are also updated. Nightly, after the batch processes, the relevant data fields are summed and compared with the totals. Unbalanced conditions are reported and corrected. This example describes: a) Segregation of duties b) Application output control c) Application edit check d) Applicaiton input control
