C++ solutions to Project Euler problems

Project Euler Solutions in C++

This repository holds solutions to the Project Euler Problems implemented in C++. Most of the solutions here are not optimized much and use the usual method for solving these problems.

How This Project is Organized

To check out how a solution is implemented, go to the solutions directory, where you will see a folder structure as follows:

solutions/
├── data/
    ├── triangles.txt
    └── ...
├── Problem001.cpp
├── Problem002.cpp
└── ...

In this folder structure, each of the files labeled Problem***.cpp contain the corresponding Project Euler problem's solution. For example, the code for Problem 1 is located in Problem001.cpp, and the file contains the following code:

int main()
{
    int sumMultiples = 0;
    for (int i = 0; i < 1000; ++i)
    {
        /*
         * ... Solution code ...
         */
    }
    
    std::cout << sumMultiples << "\n";
}

Each of the solutions are independent of one another, don't depend on other files (other than the data files, see below), and have their own main function which solves the problem and prints out the solution to the console. Using this code is as easy as downloading and running the file.

The data directory in the folder structure contains the data files that some problems need for their solutions. For example, Problem 102 needs a file called triangles.txt for its solution. Thus, for Problem 102, there will be a file called triangles.txt in the data directory.

Compatibility

All of the solutions in this project are fully conformant to standard C++14, and are platform-independent.

1. Pull Requests

   Unfortunately, since this is a solo project being done by me, I will not accept pull requests of any kind. Therefore, any opened pull requests will be immediately closed.

2. Issues

   If an error is found in one of my solutions, feel free to open an issue here, specifying exactly what went wrong and where, so I can easily fix it.
