Relational Operators or Comparison Operators

            These operators are used to compare two values to one another.


                                                                                Example
                Operator         Name                 Description             (x=8 and y=6)         Output



                                             It checks if the values of two
                                             operands are equal or not. If
                    ==            Equal                                            x == y             False
                                             the values are equal, then the
                                             condition becomes true.


                                             It checks if the values of two
                                             operands are equal or not. If
                    !=          Not equal                                          x != y             True
                                             the values are not equal, then
                                             the condition becomes true.


                                             It checks if the value of left
                                             operand is greater than the
                    >         Greater than   value of the right operand.           x > y              True
                                             If yes, then the condition
                                             becomes true.

                                             It checks if the value of the
                                             left operand is less than the
                    <           Less than    value of the right operand.           x < y              False
                                             If yes, then the condition
                                             becomes true.

                                             It checks if the value of the
                                             left operand is greater than
                              Greater than
                    >=                       or equal to the value of right        x >= y             True
                               or equal to
                                             operand. If yes, then the
                                             condition becomes true.


                                             It checks if the value of the
                                             left operand is less than or
                               Less than or
                    <=                       equal to the value of the             x <= y             False
                                 equal to
                                             right operand. If yes, then the
                                             condition becomes true.



            Logical Operators
            These operators are used to make decision on two conditions. Logical Operators are used with

            boolean values and return boolean value as output.
