Discuss why reading data from a file is a better option than reading it from the user.
A file is a resource for storing information, which is available
to a computer program and is usually based on some
kind of durable storage. A file is "durable" in the sense that it
remains available for other programs to use after
the program that created it has finished executing. Computer files
can be considered as the modern counterpart of
paper documents which traditionally are kept in office and library
files, and this is the source of the term.
when getting input from user, they might be entered wrong
input,
but with the files the is already stored in formatted way.
and we can run the application with out interception and
gets the expected results
when using files.

A program reads files from disk. It processes each file, then writes the processed file back to disk before reading and processing the next file. Assume that the reading of the file from a local disk takes 5 ms, the processing of the file takes 10 ms, and the writing of the processed file back to the local disk takes 15 ms. How long does it take the program to process 100 files from the local disk? [5 marks] a....
The input file should contain (in order): the weight (a number greater than zero and less than or equal to 1), the number, n, of lowest numbers to drop, and the numbers to be averaged after dropping the lowest n values. The program should also write to an output file (rather than the console, as in Horstmann). So you should also prompt the user for the name of the output file, and then print your results to an output file...
JAVA DATA STRUCTURES: Reading a Text file of words into two different data structures 1. Use a Binary search tree and then 2.Use a Hash Map. *USE BOTH BINARY & HASH MAP* * Get the file name as a user input.* Present a menu to the user with the below options: 1) Delete the first occurrence of a given word. 2) Delete all the occurrences of a given word.
FUNCTIONS In this assignment, you will revisit reading data from a file, and use that data as arguments (parameters) for a number of functions you will write. You will need to: Write and test a function square_each(nums) Where nums is a (Python) list of numbers. It modifies the list nums by squaring each entry and replacing its original value. You must modify the parameter, a return will not be allowed! Write and test a function sum_list(nums) Where nums is a...
