This is C++

modify the Test Scores program from chapter 6 so it uses some of the algorithms presented in this chapter. When youre done, a test run should look like this:

This program is based on exercise 11-1in the textbook:

#include

#include

#include

using namespace std;

int main()

{

cout

cout

vectorint> scores;

int score = 0;

while (score != -1) {

cout

cin >> score;

if (cin.fail()) {

cin.clear(); // clear error bits

cin.ignore(1000, ' '); // discard input up to end of line

cout

}

else if (score > 100) {

cout

}

else if (score

cout

}

else if (score > -1) { // valid score add to vector

scores.push_back(score);

}

}

if (scores.empty()) { // vector is empty

cout

}

else { // vector contains scores

// calculate total of all scores

int total = 0;

for (int score : scores) {

total += score;

}

// get the count and calculate the average

auto score_count = scores.size();

double average = static_castdouble>(total) / score_count;

average = round(average * 10) / 10;

// display the score count, total, and average

cout

}

}

1. Modify the program so it sorts the scores in descending sequence. To do that, use the sort() algorithm with a function that specifies the sort order.

2. Add code that displays the sorted scores as shown above. To do that, use the for_each() algorithm with a function that displays a score.

3. Add code that gets and displays the highest and lowest scores.

4. Add code that gets the number of scores that are equal to 100. Then, display that number.

5. Modify the code that gets the total of the scores so it uses the accumulate() algorithm instead of a range-based for loop

6. Modify the code to alert the user is less than 5 scores are input.

7. Modify the code to only consider the highest 4 scores.

The Test Scores program Enter test scores from 0 to 100. To end the program, enter -1. Only the highest four scores are counted.
