Task - Improving the Calculator
The code for the calculator which we created in the previous task is given below. Your task is to add checks to ensure proper user input.
- Add a check to make sure that the user enters appropriate input for the
opr
variable. The input should not be empty and should only be equal to+
,-
,/
or*
. In case of wrong input, it should prompt the user again for entry. Similar to point 1, add checks forfirst
andsecond
. Make sure the user enters a valid number.
There can be multiple ways to do this. As long as it satisfies the condition, it is a valid solution. Ideally there should be 3 separate try-catch statements for the 3 inputs. You can put all the try-catch statements in a single loop, or separate loops, it is up to your preference.
