C++ Challenge!! Search Metrics Link to the 100,000 Random Integers:  https://1drv.ms/t/s!AuFS4mkcuYyBjHZ_SIudb93bq2uy In this exercise you will explore the performance difference between sequential search and binary search. To do so write a program that performs the following tasks: Prompt the user for a file containing 100,000 unsorted integers Read those integers into an array Prompt the user for a search item Search for that item (using sequential search) and report the number of comparisons required. Sort the array. Note that this will take about a minute. Search for that item again (using binary search) and report the number of comparisons required. You will need to modify both of the search functions to report the number of comparisons that were made during the search.  Use your program and the file of 100,000 integers provided here to answer the six questions in the quiz.

What header file must be included *Match* 1. to perform a mathematical function like sqrt   2. to use random numbers   3. to use random numbers   4. to use stream manipulators like setprecision   A. iostream B. cmath C. iomanip D.cstdlib

Given: string s; int first, last; Write code to repeatedly validate that first is less than last and both first and last are valid indexes of the string s. Then print all characters of the string s from index first to last inclusive. Example Output 1 Enter a string and two indexes: Queensborough 25 eens Example Output 2 Enter a string and two indexes: Science 2 10 Enter a string and two indexes: Science -15 Enter a string and two indexes: Science 2 4 ien

Two of the menu options (#2 and #3) are unfinished, and you need to complete the code necessary to write to and read from a binary file.  You will need to read through the code to find the functions that are called by these options, and then supply the missing code. Please help me get menu 2 and 3 to display properly.the .cpp and .h have the information:.cpp file:  // Corporate Sales Data Outputusing namespace std; #include <iostream>#include <fstream>#include <stdlib.h>#include "HeaderClassActivity1.h" int main() {    Sales qtrSales[NUM_QTRS];    while (true) {        cout << "Select an option: " << endl;        cout << "1.

QUESTION 1 Write a program to read and store four student's name and their Salaries, sort them into an order name, based on Salaries from the smallest to the largest, then print them out. The student's name and their Salary values should be typed in by the user in response to a prompt message. Save the file as SortName_yourlD.java Attach File Browse My Computer

9. What function was used in cell C15?a. =COUNTIF()b. =COUNT()c. =COUNTA()d. =LEN()

9b_act2. Please help me answer this in python programming.

When a file has an index directory, it means that the file may be randomly accessed.
