Write code to read student data from a csv file and add (prepend) that into a...
Java code to read from .csv file i currently have a .csv file that looks like this: 39.743222, -105.006241, Hospital 39.743981, -105.020017, Home 39.739377, -104.984774, Firehouse 39.627779, -104.839291, McDonald's 39.731919, -104.961814, Chipotle I need to write code to extract the doubles from each line to use for my Linked List. this is what i have so far: Scanner in = new Scanner(new FileInputStream(DATA_FILE));
Must be written and C, and compile with MinGW. Thank you! am Specification For this assignment, you will write a multi-file C program to define, implement and use a dynamic linked lists. Please refer to Lab 07 for the definition of a basic linked list. In this assignment you will need to use the basic ideas of a node and of a linked list of nodes to implement a suit of functions which can be used to create and maintain...
Write a program that will first receive as input the name of an input file and an output file. It will then read in a list of names, id #s, and balances from the input file specified (call it InFile.txt) which you will create from the data provided below. The program will then prompt the user for a name to search for, when it finds the name it will output to a file (call it OFile.txt) the person’s id#, name,...
C++ Data Structure Write a program to read a list of students from a file and create a list. The program should use a linked list for implementation. Each node in the linked list should have the student’s name, a pointer to the next student, and a pointer to a linked list of scores. There may be up to four scores for each student.

(In C) 8.12 LAB: Warm up: Contacts You will be building a linked list. Make sure to keep track of both the head and tail nodes. (1) Create three files to submit. ContactNode.h - Struct definition, including the data members and related function declarations ContactNode.c - Related function definitions main.c - main() function (2) Build the ContactNode struct per the following specifications: Data members char contactName[50] char contactPhoneNum[50] struct ContactNode* nextNodePtr Related functions CreateContactNode() (2 pt) InsertContactAfter() (2 pts) Insert...
Please write a c++ header file, class implementation file and main file that does all of the following and meets the requirements listed below. Also include a Output of your code as to show that your program works and functions properly. EXERCISING A DOUBLY-LINKED LIST CLASS This project consists of two parts, the second of which appears below. For the first part, write a class that implements an unordered list abstract data type using a doubly-linked list with pointers to...
