I was just checking an answer and realized that CHAR_BIT isn\'t defined by headers as I\'d expect, not even by #include <bitset>, on newer GCC.
I\'m sure this is fairly simple, however I have a major mental block on it, so I need a little help here!
In my program, I am using BitArrays to represent 160 bit numbers. I want to be able to add, subtract, increment and decrement these numbers, wha开发者_高级运维t is the algorithm for doing this?
I want to have a class property that allow for an expression to take place on the right side of the equals sign. All versions of PHP choke on the following code, but it is written in this way to allow
I\'m rather ashamed to admit that I don\'t know as much about bits and bit manipulation as I probably should. I tried to fix that this weekend by writing some \'revers开发者_如何学Pythone the order of
I recently picked up a copy of Applied Cryptography by Bruce Schneier and it\'s been a good read.I now understand how several algorithms outlined in the book work, and I\'d like to start implementing
I have been trying to solve this problem for a while, but couldn\'t with just integer arithmetic and bitwise operators. However, I think its possible and it should be fairly easy. What am I missing?
I am reading a file byte-by-byte. Say for example i have this byte: 0x41 (0100 0001) represented in hex.
May I know how can I do PHP >>> ? Such operators is not available in PHP, but is available in Javascript.
I am having trouble understanding what is happening in the two lines with the 0xFF7F and the one below it.There is a link here that explains it to some degree.
