Exceptionless Programming

November 28, 2012 00:00

I am a big fan of writing code that generates no runtime errors. This is an implementation of a function that takes the first element of an array.

template<typename T>
T first(std::vector<T> array)
{
    if (array.size() == 0) { throw EmptyArrayException(); }
    return array[0];
}

public static Color ColorFromAhsb(int a, float h, float s, float b) {

    }
    if (0f > h || ...
