Arithmetic Operator

• Unary
  • ++N, --N, N++, N--
• Binary
  • +, -, *, /, %

Relational Operator

• Returns Boolean value
• Types
  • ==, !=, >, <, >=, <=

Logical Operator

• Used to connect multiple expressions or conditions together
• Types
  • &&, ||, !

Bitwise Operator

• Operate on bits and perform bit-by-bit operations
• Types
  • & => AND
  • | => OR
  • ~
    • After inverting the 1st bit represents the sign => 1 means -ve, 0 means +ve
    • Take 2's complement of rest to find the number
  • ^ => XOR
  • n >> N
    • Right Shift, Generally value of 'n' gets divided by 2N
    • In case of +ve number Padding with 0, In case of -ve number it is Compiler dependent
  • n << N
    • Left Shift, Generally value of 'n' gets multiplied by 2N
    • In case of +ve number Padding with 0, In case of -ve number it is Compiler dependent

Assignment Operator

• Types
  • =, +=, -=, *=, /=

Miscellaneous Operator

• Types
  • & => Memory Address
  • * => Pointer
  • , => Used while printing in console
