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_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.
