Two types of operators:
  Unary
  Binary

Unary examples
  -a  - negate
  *a_num - dereference an address
  &num   - take address from an variable

Binary operators
  a - b  - subtraction
  a + b  - addition
  a * b  - multiplication

Bitwise and
Symbol: &
Logical equivelent: &&
   01101001
 & 10110101
 ----------
   00100001

Bitwise or
Symbol: |
Logical equivelent: ||
   01101001
 | 10110101
 ----------
   11111101

Bitwise xor
Symbol: ^
Logical equivelent: !=
   01101001
 ^ 10110101
 ----------
   11011100

Applications
Clear bit:
   10010110
 & 11111011
 ----------
   10010010

   10010110
 | 00100000
 ----------
   10110110

Is the 5th bit set?
   10010110
 & 00010000
 ----------
   00010000


Bit shift
Left bit shift:  <<
Right bit shift: >>
  10010110 << 2 = 01011000
  unsigned
  10010110 >> 2 = 00100101
  signed
  10010110 >> 2 = 11100101
  00010110 >> 2 = 00000101

Application: make a single bit at a given index
  00000001 << i
  00000001 << 4 = 00010000
 
Inversion, bitwise not
Symbol: ~
Somewhat comparable to -
  ~01101001 = 10010110
  -01101001 = 10010111
