Examples of code that runs but is not well typed? [closed]


What are some examples of code that is not well-typed but still runs without errors? I know that some examples include adding a char to an integer and using a pointer type as an integer. But can you come up with others?
The reason I am asking is that I read that C++ has many examples of those programs – but the author didn’t give any examples lol.
