1. Create a file named dedup.js. Write a program that removes duplicates from an array. The program should be able to read an unspecified number of numbers input by the user. The user should enter a negative number when they are done entering scores. The program should remove all duplicates from the array and then iterate over the new array and display it. dedup.js const readline = require('readline'); const rl = readline.createInterface({ input: process.stdin, output: process.stdout }); const numbers = []; function readInput() { rl.question('Please enter a number or enter a negative to exit: ', (input) => { if (input < 0) { let deduped = [...new Set(numbers)]; console.log('Your array without duplicates is:', deduped); rl.close(); } else { numbers.push(Number(input)); readInput(); } }); } readInput(); 2.

Write a function that reads all the numbers from a file into an array. The file is already open and there is no bad data in the file. The data is one number per line and an unknown number of lines of data. The function should read data until either end of file is detected or the array is full. Prototype void readData( ifstream& iFile, double numbers[ ], int size, int& count); iFile - already open ifstream numbers[ ] - array to store data size - the size of the array. count - the number of values read and must be set by the function before returning.

Do not copy paste from any source else downvote Write a void function that will merge the contents of two text files containing chemical elements sorted by atomic number and will produce a sorted file of binary records. The function’s parameters will be three file pointers. Each text file line will contain an integer atomic number followed by the element name, chemical symbol, and atomic weight. Here are two sample lines: 11 Sodium Na 22.99 20 Calcium Ca 40.08 The function can assume that one file does not have two copies of the same element and that the binary output file should have this same property. Hint: When one of the input files is exhausted, do not forget to copy the remaining elements of the other input file to the result file.
What parameter values are necessary when using Function 716Ch to read a binary array from an open file?
C++ program to find out if a file is sorted or not? Using header file The “sort.h” contains the Boolean method that check the file are sorted or not and return true. The “sort.h” is included in the main.cpp.
