It's human nature to imagine that we understand a concept but struggle to use it. Applying our understanding to increasingly complex problems helps identify where our understanding is incomplete and reinforces it as we continue learning, making it more memorable.

The tooltips display each member in its own "public" or "private" section, but programmers typically group them into just two or three sections. Constructor functions often initialize data members, so programmers typically name the function's parameters similarly to the members. Prefixing each parameter with an 'a' (for argument) is common.
