As at any time, bear in mind the intention of those naming and layout guidelines is consistency and that aesthetics vary immensely.
Construct your excellent modest foundation library and use that, as opposed to reducing your volume of programming to glorified assembly code.
This easy guideline illustrates a subtle concern and reflects present day makes use of of inheritance and object-oriented layout concepts.
Let's say you will find much less than n elements from the array pointed to by q? Then, we overwrite some probably unrelated memory.
