Normally, C requires that a binary operator\'s operands are promoted to the type of the higher-ranking operand. This can be exploited to avoid filling code with verbose casts, for example:
I am currently reading a book abou开发者_JS百科t \"bit fiddling\" and the following formula appears:
how do i define 24 bit array in c++? (variable declaratio开发者_如何转开发n)There is no 24-bit variable type in C++.
I know it is possible to assign an unsigned char to an unsigned short, but I would like to have more control how the bits are actually assigned to the unsigned short.
Given a series of bits, what\'s the best way to overwrite a particular range of them. For example, given:
Note my question is 开发者_Go百科not regarding != but |= A usage example is here I assume that x |= y is the same as x = x | y but I could not find confirming documentation and wanted to be sure
i tr开发者_开发百科ied with the following code , but i can\'t understand why it\'s giving me wrong answer. i am computing the 2\'s complement and adding with another no.
I come across a very tricky problem with bit manipulation. As far as I know, the smallest variable size to hold a value is one byte of 8 bits. The bit operations available in C/C++ apply to an entire

A database table, lets say burger, contains a field that stores bits as a开发者_Go百科n integer value, so it has value of either 1,2,4,8,16 ...
