Factorial

Note:

This code was written during a crunch period and isn't perfect. There will be some errant spacing, some files will be using namespace std, etc. But it's all still usable and can be a handy guideline if you're learning Data Structures.

int factorial(int num)
{
    if (num == 1)
    {
        return 1;
    }
    else
    {
        return num * factorial(num - 1);
    }
}

int main()
{
    std::cout << factorial(10) << '\n';
}
