The first lab assignment is an exercise in the use of the exception and handling of exceptions. There is a simple calculation program listed below, which takes integers as input for the A and B sides of a right triangle and calculates the hypotenuse. However it does nothing to handle the situation where a user enters data which is non-integer or even non numeric.

Input Commands:

A enter value for side A

B enter value for side B

C calculate

Q quit the program

The program should repeat itself if the user wishes; this makes it easier to test. Values for A and B will be cleared to 0 (zero) after each calculation.

Your task today is to modify that program to handle the bad input situation with the use of exception handling. Bad inputs are:

Non-numeric values where numeric values are expected

Numeric values where non-numeric values are expected

Input command, not A, B, C or Q

The program should not terminate but should inform the user of the specific error and should re-request only the input value which was in error

Testing:

Test your program with the following test cases;

A A A A B A B X Q

3 3 0 X X 3 3

B B B C C

4 0 3

C C C

In all cases the program should ask for only the input values that were invalid and should continue with the values that were correct. The program should never crash!
