I was recently asked in an in开发者_StackOverflow社区terview how to set the 513th bit of a char[1024] in C, but I\'m unsure how to approach the problem. I saw How do you set, clear, and toggle a singl
i knowthat if number is power of two,then it must satisfy (x&(x-1))=0; for example let\'s take x=16 or 10000 x-16=10000-1=01111 and (x&(x-1))=0;for another non power number 7 for example, 7=01
In the following assembly code I am trying to implement a multiplication method using bitwise shifts etc but I am getting two errors over and over, \"too many memory references for \'mov\'\" as well a
I have been reading a lot of articles lately about programming practice, design and so forth and was curious about the real performance gains from implementing multiplication as bit shifting.
Can you help me with the translation to c# of this 3rd part API method: I also didnt understand everything that is happening at the bit operations..
For unsigned int x, is it possible to calculate x % 255 (or 2^n - 1 in general) using only the following开发者_JAVA百科 operators (plus no loop, branch or function call)?

I an using the following function to calculat开发者_JS百科e the set bits in an integer, and it works for positive numbers, but not for negative numbers. Can anyone explain why?

I\'m looking for ways of converting an array of byte values in DWord using Ruby. For example: [255,1,255,2] -> 11111111 00000001 11111111 000000010
