Code:
Maybe I should try it. As of now I'm producing very deeply nested code blocks with little or no concern as to the consequences... should I be?
I am no C++ expert, but I would take small concern at this. Later, when you or another person wants to review or change any of your code, he/she may find it hard to follow without good indentation practice included.
My guess would be to review what you have done and make small changes here and there. If you begin a new program/project, indent to a rule of three spaces per code block ect. If you keep all the indents to the same spacing size, your code will look nicley formatted.
