DataInputStream reads bytes from the stream and converts them into appropriate primitive type values or strings.

Octave/Matlab: How do I write a script that reads in the file and then collects the values from the columns into a vector like: file1.txt 10 11 12 13 14 15 So the output should look like: A = [10,13] B = [11,14] C = [12,15]

JAVA PROGRAM (Create large dataset) Create a data file with 500 lines. Each line in the file consists of a faculty member’s first name, last name, rank, and salary. The faculty member’s first name and last name for the ith line are FirstNamei and LastNamei. The rank is randomly generated as assistant, associate, and full. The salary is randomly generated as a number with two digits after the decimal point. The salary for an assistant professor should be in the range from 50,000 to 80,000, for associate professor from 60,000 to 110,000, and for full professor from 75,000 to 130,000. Save the file in Salary.txt.   Here are some sample data: FirstName1 LastName1 assistant 60055.95 FirstName2 LastName2 associate 81112.45 . . . FirstName500 LastName500 full 92255.21

In a loop, prompt the user to enter name data consisting of a first name, middle initial, last name, and employee number (type unsigned long) Then, using formatted LO with the insertion () operator, write these four data items to an ofstream object. Don't forget that strings must be terminated with a space or other whitespace character. When the user indicates that no more name data will be entered, close the ofstream object, open an ifstream object, read and display all the data in the file, and terminate the program.

Need help to implement networking in python Server.py Load data from file This option will ask the user for a fully qualified path and will load a JSON file containing the information for users and pending messages. The format of the JSON file will be defined based on your implementation and it will the same used to save the data into file (menu option #4). Functionalities the server must provide: 1) User Sign Up: adds a user identified by a phone number to the system. a) Protocol: USR|username|password|display_name b) Response: 0|OK for success. 1| for an error. c) The server should validate that the username does not exist 2) User Sign In: verify user credentials a) Protocol: LOG|username|password b) Response: i) 0|OK → the credentials are correct. ii) 1|Invalid Credentials iii) 2|Already Logged In → in case that the user is logged in from another client. c) This will help the server knowing which user is connected. d) The server should keep a list of connected clients, which should…

Describe scenarios where you might need to wrap an InputStream with other stream types, such as DataInputStream or BufferedInputStream.
