Bitwise operations are those that operate on one or more bits of data, as opposed to larger units of data. For example, in C++, there are the bitwise operators "^" (exclusive or), "&" (and), "|" (or), and "~" (bitwise complement). Using these symbols, it is possible to determine if a bit is set or unset, combine sets of bits, find common bits, or invert all the bits at once. This allows the use of a single field (such as an int variable) to hold multiple pieces of data. Algorithms that concern themselves with saving space, such as compression algorithms, embedded system code, and so on, will often use bitfields instead of entire bytes of data whenever practical.

Explain the Difference between bitwise operator ' and ' and address operator ' and ' of pointer?

The bitwise logical operator and (&) calculates the bitwise logical and of two integral values. It is a binary operator.The address of (&) operator returns the address of the value to its right. It is a unary operator.The distinction between the two is one of context. The logical and operator will follow (and be preceeded by) a value, while the address of operator will follow an operator.
