- C++ Problem!! Sort A List Of Integers Given a file of 100,000 unsorted integers, write a program that first prompt user to enter file name and reads those integers into an array and sorts the integers in the array. The program should then prompt the user for an index, and then display the integer at that index. For example, if the array contains ten integers and the contents are 79 4 42 51 12 22 33 17 91 10 after sorting, the integer at index 6 is 42 Download the "List of 100,000 Unsorted Integers" from below link and sort that list, then enter the value at index 10000 (ten thousand) for a screenshot. https://1drv.ms/t/s!AuFS4mkcuYyBjHZ_SIudb93bq2uy?e=CsyvZjarrow_forward59. Question: Write a C++ program. Using Dynamic Array, read a data file containing some names into a dynamically declared array. Note that the total number of names is not known so your program should determine it. Create a second array that contains the names in alphabetical order. Produce an output file containing the alphabetized list. Important: Do not copy codes from prepinsta.com.arrow_forwardThis is for C++ Design an application that uses three identical arrays of at least 20 integers. It should call each module on a different array, and display the number of swaps made by each algorithm. 8 Sorting Benchmarks (bubble, selection & insertion sort) The following represents the output from 3 separate files: BubbleSort, SelectSort and InsertionSort. Don't ask the user to enter any numbers, but 'hard code' the values in the "Original order" as shown.

- Write a function that will read input into an array from a filearrow_forwardC++ Create a new file named array_ptrs.cpp and in this file, write a program that does the following: Defines an array of integers called my_ints with a pre-specified size of 4. Populates my_ints with input data provided by the user Defines an array of pointers called my_ptrs of the same size as my_ints and initializes the pointers in my_ptrs to point to corresponding elements of the array my_ints (refer to the “initial state” in the example shown below) Sort the array of pointers my_ptrs in a way such that the pointer at index 0 (i.e., the first element of my_ptrs) points to the smallest element in my_ints, the pointer at index 1 points to the next larger element in my_ints, etc. (refer to the “State after sorting my_ptrs” in the example shown below). Traverse the array my_ptrs and print the values being pointed to by each pointer in this array. Take a screenshot of a sample output and upload the picture as part of your assignment submission.arrow_forward
