6. Operators #

Created Friday 18 October 2019

• int/int gives an int, not a float.
• any operation using a float/double gives a float/double.
• Remember, = is also an operator just like =,-,* etc. if we write (a=2) where ‘a’ has been previously been defined/declared, then assignment occurs, and then the left hand value is the result of the expression, which is two in this case.

Types of operators:

• Arithmetic operator:
  • /
  • % can be used only when both operands are int.
• Relational operator:
  • ==
  • !=
  • <
  • <=

  • =

• Logical operator:
  • &&
  • ||
  • !
  • there’s no logical XOR in C++. We can do bitwise to achieve the same.
