// Vectors and matrices are really useful when doing 2D/3D, esp in games

// because the way C doesnt allow to define different operators for structs(that is, i cannot do vec3 + vec3)
// I know i could have chosen to use c++ or python but i oppose using c++ and decided to take the opportunity to work
// on my C programming skills(and i also dont like python)
