While adding an even number by itself the result is being 
displayed wrongly, The result obtained in 1 + original 
result which needs to obtained.

when ever adding the even number itself , the value added
automatically , 

so the code is wrong , if the even number means, the value +
1 is  automaticallly added .

Condition:
Check for the display of additional values for even numbers
Input:
(i)Enter the even number(ii)Enter the + symbol in the 
calculator(iii)Enter the same even number and press the = 
symbol in the calculator
Expected Result:
It should display the value as the additon of those two 
values

FOR ODD NUMBERS,CALC COMPUTES WELL
BUT COMING 2 EVEN NUMBERS,1 IS BEING ADDED TO THE SUM OF TWO
EVEN NUMBERS....
HENCE THERE MIGHT BE A BUG IN THE LOOP FOR ADDING TWO EVEN
NO.S',SINCE IT IS A CALC...WHICH HAS A LED DISPLAY THE
PROBLEM MIGHT B WITH THE LIGHT ELECTRIC DIODES..........

Hi,

The question is kind of Abstract. There definitely is a bug 
with the functionality of the Calculator. I would say we 
could categorize Bug report outline as follows.

BugId : Autogenerated by Tool or as maintained by Tester.
BugSummary : Addition functionality failing for Even 
numbers. 
Application : Calculator.
Bug Description : Whenever User tries to add 2 even number, 
the resultant is displayed as one more than the actual 
expected result. Functionality works fine correctly for Odd 
Number addition. 
Severity : High.
Priority : High.
TestDataUsed : 2+2, 4+4, 6+6..........1+1,3+3........
Date Detected : ##/##/####
Detected By : Tester Name.

We would also have to test whether 2 odd Numbers are added 
up correctly on consecutive operations. Incase the result 
fails for the second attempt, we would have to change our 
Bug Report accordingly.

hi guys

here i am not giving my  exact answer but I likes to express
my views on  this sort of queries. in this situation as a
Test Engineer 
 u should not say addition of even numbers is giving
problem, instead of that u should be very specific about the
problem in this case every addition even numbers resultant
is added with 1 ex; 2+2=5, 4+4=9 etc, so you  have to be
very  specify these minute things properly  because your 

submitting report to your senior 

other then that u should mention:
 
1.severity and priority
2.Take screen shot & attachments (if possible)
3. define the sentence short and clear if it is analytical
like above query, 
4.define the steps to reproduce(show the  sample calculation
in above  query)
5.define the environment used(atleast show this field if ur
not sure also)
finally try to bring general bug report formate in any of
the bug
like who detected assigned person name, date, status of bug etc

          cheers

when an even no. is added to it, the result obtained is 
incorrect always 1 less than the result is displayed.
