+# Help
+
+## Running the tests
+
+Running the tests involves running `cmake -G` and then using the build command appropriate for your platform.
+Detailed instructions on how to do this can be found on the [Running the Tests][cpp-tests-instructions] page for C++ on exercism.org.
+
+## Passing the Tests
+
+When you start a new exercise locally, the files are configured so that only the first test is performed.
+Get that first test compiling, linking and passing by following the [three rules of test-driven development][three-laws-of-tdd].
+Create just enough structure by declaring namespaces, functions, classes, etc., to satisfy any compiler errors and get the test to fail.
+Then write just enough code to get the test to pass.
+Once you've done that, uncomment the next test by moving the line `if defined(EXERCISM_RUN_ALL_TESTS)` past the next test.
+
+See the example below from the Bob exercise (file `bob_test.cpp`, line 15):
+
+```diff
+-#if defined(EXERCISM_RUN_ALL_TESTS)
+TEST_CASE("shouting")
+{
+    REQUIRE("Whoa, chill out!" == bob::hey("WATCH OUT!"));
+}
++#if defined(EXERCISM_RUN_ALL_TESTS)
+```
+
+Moving this line past the next test may result in compile errors as new constructs may be invoked that you haven't yet declared or defined.
+Again, fix the compile errors minimally to get a failing test, then change the code minimally to pass the test, refactor your implementation for readability and expressiveness and then go on to the next test.
+
+Try to use standard C++17 facilities in preference to writing your own low-level algorithms or facilities by hand.

+# Hints
+
+## General
+
+- `while` loops are used for _indefinite_ (uncounted) iteration
+- `for` loops are used for _definite_, (counted) iteration.
+- The keywords `break` and `continue` help customize loop behavior.
+- `std::to_string()` from `string` library can be used to convert a integer to string
+
+Also being familiar with the following can help with completing the tasks:
+
+- [`vectors`][vectors]: indexing, size, [`<vector>.emplace_back`][emplace], [`<vector>.pop_back()`][pop].
+- [`string`][string]: using the `+` to concatenate strings, integer to string conversion, [`to_string`][to\_string].
+
+## 1. Rounding Scores
+
+- `While` loops will continue to execute until their test condition evaluates to `False`.
+- `<vector>.back()` will return the last item in a `vector`.
+- `<vector>.pop_back()` will remove the last item in a `vector`.
+
+## 2. Non-Passing Students
+
+- A results counter does need to be set up and _incremented_ -- you'll want to `return` the count of non-passing students when the loop terminates.
+
+## 3. The "Best"
+
+- - Having an empty `vector` to add the "best" marks to is helpful here.
+- `<vector>.emplace_back()` can help add things to the results `vector`.
+
+## 4. Calculating Letter Grades
+
+- These are _lower thresholds_. The _lower threshold_ for a "D" is a score of **41**, since an "F" is **<= 40**.
+- `static_cast<int>` without parameters should round off increments nicely.
+- You are expected to return an array, not a vector.
+
+## 5. Matching Names to Scores
+
+- If both containers are the same length and sorted the same way, could you use the `index` from one to retrieve a `value` from the other?
+- `std::to_string(int)` can be used to convert a number to string.
+- Don't forget the follow the format of the example's output.
+
+## 6. A "Perfect" Score
+
+- There may be or may not be a student with a score of 100, and you can't return an empty string without checking **all** scores.
+- The `control flow` statements `continue` and `break` may be useful here to move past unwanted values.

+# Making the Grade
+
+Welcome to Making the Grade on Exercism's C++ Track.
+If you need help running the tests or submitting your code, check out `HELP.md`.
+If you get stuck on the exercise, check out `HINTS.md`, but try and solve it without using those first :)
+
+## Introduction
+
+## Arrays and Vectors
+
+C++ offers different containers to store elements of the same type in an ordered way.
+There is `std::array` for containers of a fixed size and `std::vector`, which comes with dynamic resizing capabilities.
+
+### Construction
+
+When you declare an array or a vector you need to specify the type of elements, that container will hold.
+Arrays also need a size.
+Look at these examples to see the two container types' initializations:
+
+```cpp
+#include <array>
+#include <string>
+
+// std::array<element_type, size> variable_name {list of elements}
+std::array<std::string, 3> indie_rock {"yeah", "yeah", "yeah"};
+// indie_rock contains the elements "yeah" three times
+```
+
+Vectors usually need more space, as they allocate memory for further growth.
+You do not need to specify a size:
+
+```cpp
+#include <vector>
+
+// std::vector<element_type> variable_name {list of elements}
+std::vector<int> countdown {3, 2, 1};
+// countdown contains the elements 3, 2 and 1
+```
+
+> Note: You do not need to know the exact mechanics behind the template concept yet, it will have its own concept further down the syllabus tree.
+
+### Element access
+
+Vectors and arrays share the same functions to access their elements.
+You can use the member functions `front` and `back` to get the first and last elements of the container.
+There is also `at` and the `[]` operator to access specific elements.
+
+```cpp
+countdown[0];
+// => 3
+countdown.at(2);
+// => 1
+countdown[1] = 4;
+// countdown now contains 3, 4 and 1
+indie_rock.back() = "yeahs";
+// indie_rock is now "yeah", "yeah", "yeahs"
+```
+
+> Note: If you pick a position that is not in the range of your container, `[]` might lead to undefined behavior.
+> The `at` function would raise an exception, which might make your life easier in the long term.
+
+### Vector modifiers
+
+As a `vector` is not fixed in size, it is possible to add or remove elements.
+Two common functions for that purpose are `emplace_back` and `pop_back`.
+
+```cpp
+std::vector<std::string> witches {"Holly", "Alyssa", "Shannen"};
+witches.pop_back();
+// Shannen is no longer with the witches
+witches.emplace_back("Rose");
+// Rose has joined the team
+```
+
+### Capacity
+
+You can check the containers for emptiness with the member function `empty`.
+If you want to know the number of elements, you can use `size`.
+
+## Instructions
+
+You're a teaching assistant correcting student exams.
+Keeping track of results manually is getting both tedious and mistake-prone.
+You decide to make things a little more interesting by putting together some functions to count and calculate results for the class.
+
+## 1. Rounding Scores
+
+While you can give "partial credit" on exam questions, overall exam scores have to be `int`s.
+So before you can do anything else with the class scores, you need to go through the grades and turn any `double` scores into `int`s.
+
+Create the function `round_down_scores()` that takes a `vector` of `student_scores`.
+The schools' requested rounding is a truncation.
+Lucky for you, C++ can cast one type into another with `static_cast`.
+The `static_cast` conversion from `double` to `int` cuts off any digit after the decimal.
+This function should take the input `vector` and `return` a new vector with all the scores converted to `int`s.
+
+```cpp
+std::vector<double> student_scores {90.33, 40.5, 55.44, 70.05, 30.55, 25.45, 80.45, 95.3, 38.7, 40.3};
+round_down_scores(student_scores)
+// => {90, 40, 55, 70, 30, 25, 80, 95, 38, 40}
+```
+
+## 2. Non-Passing Students
+
+As you were grading the exam, you noticed some students weren't performing as well as you'd hoped.
+But you were distracted, and forgot to note exactly _how many_ students.
+
+Create the function `count_failed_students()` that takes a `vector` of `student_scores`.
+This function should count up the number of students who don't have passing scores and return that count as an integer.
+A student needs a score greater than **40** to achieve a passing grade on the exam.
+
+```cpp
+count_failed_students({90,40,55,70,30,25,80,95,38,40});
+// => 5
+```
+
+## 3. The "Best"
+
+The teacher you're assisting wants to find the group of students who've performed "the best" on this exam.
+What qualifies as "the best" fluctuates, so you need to find the student scores that are **greater than or equal to** the current threshold.
+
+Create the function `above_threshold()` taking `student_scores` (a `vector` of grades), and `threshold` (an `int`, the "top score" threshold) as parameters.
+This function should return a `vector` of all scores that are `>=` to `threshold`.
+
+```cpp
+above_threshold({90,40,55,70,30,68,70,75,83,96}, 75);
+// => {90,75,83,96}
+```
+
+## 4. Calculating Letter Grades
+
+The teacher you're assisting likes to assign letter grades as well as numeric scores.
+Since students rarely score 100 on an exam, the "letter grade" lower thresholds are calculated based on the highest score achieved, and increment evenly between the high score and the failing threshold of **<= 40**.
+
+Create the function `letter_grades()` that takes the "highest" score on the exam as a parameter, and returns an `array` (not a vector) of lower score thresholds for each "American style" grade interval: `["D", "C", "B", "A"]`.
+
+```cpp
+/*Where the highest score is 100, and failing is <= 40.
+       "F" <= 40
+ 41 <= "D" <= 55
+ 56 <= "C" <= 70
+ 71 <= "B" <= 85
+ 86 <= "A" <= 100
+*/
+
+letter_grades(100);
+// => {41, 56, 71, 86}
+
+
+/*Where the highest score is 88, and failing is <= 40.
+       "F" <= 40
+ 41 <= "D" <= 52
+ 53 <= "C" <= 64
+ 65 <= "B" <= 76
+ 77 <= "A" <= 88
+*/
+
+letter_grades(88);
+// => {41, 53, 65, 77}
+```
+
+## 5. Matching Names to Scores
+
+You have exam scores in descending order, and the respective student names (sorted in the order of their exam scores).
+You would like to match each student's name with their exam score and print out an overall class ranking.
+
+Create the function `student_ranking()` with parameters `student_scores` and `student_names`.
+Match each student name on the student_names `vector` with their score from the student_scores `vector`.
+You can assume each argument `vector` is sorted from highest score(er) to lowest score(er).
+The function should return a `vector` of strings with the format `<rank>. <student name>: <student score>`.
+
+```cpp
+std::vector<int> student_scores {100, 99, 90, 84, 66, 53, 47};
+std::vector<std::string> student_names {"Joci", "Sara","Kora","Jan","Indra","Bern", "Fred"};
+student_ranking(student_scores, student_names)
+// =>
+//  {"1. Joci: 100", "2. Sara: 99", "3. Kora: 90", "4. Jan: 84", "5. Indra: 66", "6. Bern: 53", "7. Fred: 47"}
+```
+
+## 6. A "Perfect" Score
+
+Although a "perfect" score of 100 is rare on an exam, it is interesting to know if at least one student has achieved it.
+
+Create the function `perfect_score()` with parameters `student_scores` and `student_names`.
+The lists are the same as in task 5.
+The function should `return` _the first_ `<name>` (as a string) of the student who scored 100 on the exam.
+
+If no 100 scores are found, an empty string `""` should be returned.
+
+```cpp
+perfect_score({"Nur", "Tony", "Fatima"}, {90, 80, 100});
+// => "Fatima"
+
+perfect_score({"Nur", "Tony"}, {90, 80});
+// => ""
+```
