Why does my TO-220 LM7805 regulator need an insulator before a heat sink?
The case of the TO-220 LM7805 regulator is device ground. If the heatsink is also ground, you do not need an insulator. If the heatsink is not ground, or if you need to maintain distinct grounds, or if the LM7805 ground is something else besides ground, you need an insulator. Its up to you, since you are responsible for system and circuit design.
When a function is used as an argument in another function?
It is called callback function. For an example see the qsort function.
Why a function is not defined in to another function?
A function is not deigned in to another function. It is because that would lead to dependency injection.
Can you declare a function in the body of another function in c language?
yes, we can not declare a function in the body of another function. but if we declare a function in the body of another function then we can call that very function only in that particular function in which it is declared; and that declared function is not known to other functions present in your programme. So if a function is required in almost all functions of your programme so you must declare it outside the main function i.e in the beginning of your programme.
When can a function prototype be omitted?
when we write definition of a function i.e; body of a function above main() function, then the function prototype be omitted. -Ramashankar Nayak,M.C.A,Pondicherry University
