After lot of search finally got this awesome things what i really expected. A big thanks and a true smile.

Why is always Indians with the strongest accents doing these videos ...

#define SET_BIT(number, Bit) (number|=(1<<Bit))#define CLEAR_BIT(number, Bit) (number&=~(1<<Bit))

[Korudo]

Your explanation of Clearing a Bit helped a ton. I didn't intuitively understand before meant that "Clear" meant "Turning Off" (setting it to 0). If it's already "Off", then it remains 0. Thanks!

[teli]

No other bits are changed during toggling (0^0 =0 and 1^0=1) so the rest of the bits remain the same.

[chetanphoenix]

For getting the bit, with the given manipulation, we don't get the bit. We get a number which is a power of 2. So I think we need to right shift the answer by the same number again.

[balassura]

Chec the part about the Clear again. It seems like you are ANDing the number by left shifting the 1 in a 0000 0001. But this will not give the right answer. Its more like left shift the 0 in 1111 1110 and then ANDing to clear the respective bit position.

You are not good in explaining things, went too fast and not at all neat.. Please reduce your pace and make the note neat, take this positively

[mushirahmedshaikh]

For getbit is not working.
Please tell us the procedure

[gbemisolaagboola]

this is so disorganized, even with good expplanation, its unclear what part you are, since its all entangled
