Introduction

In this task you will be working on a C++ File and coding it according to given task. The main motive of this task is to make you familiar with:

Git and GitHub
C++
Standard Template Library (STL)

Setting up the project

Follow the following steps to setup this project.

Fork this repository

First of all, click on the top-right corner of this repository to fork it.

Create a local clone of your fork

Then, clone your forked repository using this command:

git clone https://github.com/YOUR-USERNAME/Multiverse-CPP.git

Change your current directory to the repo's root.

cd Multiverse-CPP

Thats it!

Go through the tasks in src folder and

Then you can finally test your submission by running this command from root folder.

make

Submission

Follow the instructions to setup this project.
Complete the task by making the required changes in the files.
When done, commit your work locally and push it to your origin (forked repository).
Make a pull request to our repository, stating the tasks which you have completed.
Let us review your pull request.

Want to know about doctest? See this example

Suppose we have a factorial() function that we want to test:

int factorial(int number) { return number <= 1 ? number : factorial(number - 1) * number; }

A complete compiling example with a self-registering test looks like this:

#define DOCTEST_CONFIG_IMPLEMENT_WITH_MAIN
#include "test/doctest.h"

int factorial(int number) { return number <= 1 ? number : factorial(number - 1) * number; }

TEST_CASE("testing the factorial function") {
    CHECK(factorial(1) == 1);
    CHECK(factorial(2) == 2);
    CHECK(factorial(3) == 6);
    CHECK(factorial(10) == 3628800);
}

This will compile to a complete executable which responds to command line arguments. If you just run it with no arguments it will execute all test cases (in this case - just one), report any failures, report a summary of how many tests passed and failed and returns 0 on success and 1 if anything failed (useful if you just want a yes/no answer to: "did it work").

If you run this as written it will pass. Everything is good. Right? Well there is still a bug here. We missed to check if factorial(0) == 1 so lets add that check as well:

TEST_CASE("testing the factorial function") {
    CHECK(factorial(0) == 1);
    CHECK(factorial(1) == 1);
    CHECK(factorial(2) == 2);
    CHECK(factorial(3) == 6);
    CHECK(factorial(10) == 3628800);
}

Now we get a failure - something like:

test.cpp(7) FAILED!
  CHECK( factorial(0) == 1 )
with expansion:
  CHECK( 0 == 1 )
