Hi, @rajeshkumar1

  1. If you use fixedValue+1 then please increment first and assign the incremented value in a variable or in fixedValue variable itself and then return that variable from function.

  2. You can also try increment operator here (```return ++fixedValue), if you are not familiar with it. you can refer below mentioned link.

Note - Actually point is simple first store incremented value and then return, In your code you are returning incremented value before storing anywhere.

Please note that changing fixedValue is wrong as it is a side effects. fixedValue++ or ++fixedValue should not be correct solutions.
