Concept understanding — Bitwise Operators in C

Bitwise operators are a special feature of C that operate directly on the individual bits of integer data, rather than on whole numbers. This low-level control is one reason C is so useful for systems and hardware-related work.

The bitwise operators are:

& bitwise AND - a result bit is 1 only if both corresponding bits are 1.
| bitwise OR - a result bit is 1 if either corresponding bit is 1.
^ bitwise exclusive-OR (XOR) - a result bit is 1 if the two bits are different.
~ one's complement (NOT) - inverts every bit (each 1 becomes 0 and each 0 becomes 1).
<< and >> - left shift and right shift, which move the bits a given number of places. …

[!TLDR]

With A = 00000110 and B = 00000111, A & B = 6 and A | B = 7.

First express both numbers in 8-bit binary form:

A = 6 = 00000110

B = 7 = 00000111

(i) Bitwise AND (A & B) - a result bit is 1 only when both bits are 1:

  00000110   (A = 6)
& 00000111   (B = 7)
-----------
  00000110   = 6
``` …
