Another comparison operators

     So let’s check < = > operator  it compares the values of the left hand side value to the right hand side value if the left is greater so it will give the result 1 if both are equal so it return the value 0 and if the right value is greater so it will return -1 so let’s check by an example

                             Input                                                           Output

Case – When Statement

                         Input                                                                    Output                                               

* If we don’t write anything or write anything which is not in when statement then else statement will run and give result Hello.

 * And if we match any matching in the when statement then it will return the respective result.
