Functions and operators that return values representing true or false are called predicates. C offers operator predicates that test the relationship between a pair of numbers:

Predicate Purpose\
== Are two numbers equal?\ != Are two numbers not equal?\ > Is the first number greater than the second?\ < Is the first number less than the second?\ >= Is the first number greater than or equal to the second?\ <= Is the first number less than or equal to the second?\
