It’s not meant to be an exhaustive list, but rather a collection of things that I’ve seen come up over and over again.
1) Not using const correctly: This one is pretty basic, but it still comes up all the time. If you’re declaring something as const , make sure you actually mean it! For example, if you declare a variable like this:
const int x = 3; // … do stuff with x … int y = x + 1; // ERROR!!! Can’t modify const variables! // … more stuff with x ..
