As we have seen, the following logical, relational and equality operators exist in C:
These operators are used in conjunction with decision and control statements. For Example
heart_rate > 75
performs the necessary comparison and evaluates to 1 (true) when heart_rate is over 75; and evaluates to 0 (false) when heart_rate is not greater than 75.
marks is in the range 40 to 100, (40 £ marks £ b) inclusive
(marks >= 40) && (marks <= 100)
performs the necessary comparison and evaluates to 1 (true) when marks is greater than or equal to 40 AND marks is less than or equal to 100; and evaluates to 0 (false) when the either expression is false.
