so there is a .h document and a .cpp document with a same name. there is also a .cpp document called main.cpp. .h document is provided in the last figure.

The Lab Problem We are going to work on making our own data structures using a C++ struct. Specifically, we are going to create both data members and member functions. We are going to make a 2D MathVector struct. Keep it straight, these are the mathematical entitles called Vectors (a geometric entity with direction and magnitude). Some Background So if you don't remember, here is a little background on two-dimensional vectors A vector is basically an arrow that has a magnitude (a length) and a direction (an angle with respect to typically the x axis). It usually is represented as an x y pair, where the origin of the vector is assumed to be at 0,0 and the head of the vector is as the listed x,y pair. V+W 0.0
