It assumes that you have no prior coding experience. Objectives Download Octave and run it or use https://octave-online.net/ Learn the basics of the Octave GUI. • Learn how to create a short executable file called an m-file (.m extension) and run it. • Learn what a data type is. • Learn how to declare variables of different data types. • Learn how to create matrices. • Learn how to use several of Octave’s functions for creating objects with random numbers. Instructions 1.) Create a file call it with the form exercise_1_first name_last name. Include the underscores in your file name. At the top of the file add the comment "“My first Octave assignment. I'm so excited, I just can't hide it." 2.) Create the following variables a = 2.3; b = -87.3; A = [1,2; 4,5]; Create a matrix 2 × 2 B using the rand() function.

- Implement a simplified grocery Webshop in C programming language: Create a structure that contains a set of products and their number. A product has a name, price and quantity. Create two instances of this struct. The first represents the webshop store and the other represents a cart. Print a menu for the user that contains the following items: Load webshop store from a file\ This operation loads the content of the store from a text file. The filename should be read from the keyboard. The file contains the product name, price and quantity in the following format:Apple 100 42 Orange 130 59 Raspberry 231 17 ... Write the content of the store to a file\ Read a filename from the user and write the content of the store to that file using the file format above. Insert an item to cart\ The cart contains the items that a customer wants to buy. Read a product name and the quantity from the keyboard and put this information to the cart. The price of the product should be fetched from the store.…Sample run: Your 1st vector contains the following elements January February March April May June July August September October November December Your 2nd vector contains the following elements May June JulyJAVA PPROGRAM Write a program that prompts the user to enter a file name, then opens the file in text mode and reads names. The file contains one name on each line. The program then compares each name with the name that is at the end of the file in a symmetrical position. For example if the file contains 10 names, the name #1 is compared with name #10, name #2 is compared with name #9, and so on. If you find matches you should print the name and the line numbers where the match was found. While entering the file name, the program should allow the user to type quit to exit the program. If the file with a given name does not exist, then display a message and allow the user to re-enter the file name. The file may contain up to 100 names. You can use an array or ArrayList object of your choosing, however you can only have one array or ArrayList. Input validation: a) If the file does not exist, then you should display a message "File 'somefile.txt' is not found." and allow the…
- programming language: C++ How can you generate unique id with file handling and by using data structure like linked list or algorithm? System will search first in the file when it is not there, it will increment the largest number and then input it in the system whenever the user input a new video in the list. The file will look like this: 101,Raya and the Last Dragon,Animation,Walt Disney Studio,6102,Captain America: The First Avenger,Adventure ,Marvel,10100,Captain America,Adventure ,Marvel,8A file has r=20000 STUDENT records of fixed-length. Each record has the following fields: NAME (30 bytes), SSN (10 bytes), ADDRESS (40 bytes), PHONE (9 bytes), BIRTHDATE (8 bytes), SEX (1 byte), MAJORDEPTCODE (4 bytes), MINORDEPTCODE (4 bytes), CLASSCODE (4 bytes, integer), and DEGREEPROGRAM (3 bytes). Suppose the block size is 512 bytes. (a) Calculate the record size R in bytes. (b) Calculate the blocking factor (number of tuples per block) and the number of blocks required. (c) Calculate the average block accesses it takes to find a record by doing a linear search on the file. (d) Assume the file is ordered by SSN; calculate the block accesses takes to search for a record given its SSN value by doing a binary search.Unix assignment Purpose: The purpose of this assignment is to use various concepts of the C Shell. 0.
