Answer / priya
Error: It is the term used to describe a non-conformance to
the explicitly stated requirement.
For example: Let me explain with an example. If the
requirement mentions 5 Plus 3 Divided by 4; the programmer
codes to add 5 and 3 first; and then divides the result [8]
by 4 to arrive at result 2.
But if the actual/intended application requirement is to
first divide 3 by 4 and then add 5; expecting a result 5.75
then this is a classic Design/Code Error.
Bug: Assume that the programmer has actually understood the
intended requirement correctly but has declared/stored the
result as an integer to show a result of 5 instead of 5.75 –
this is called a Bug. Here the programmer has to declare the
variable as “double or float” and not “int”.
Defect: A defect is any of the above but found/un-covered in
the “released-application” - running in the “Production
Servers” [gone “Live”] or may be in “Beta-Release”.

Answer / priya
If in the Req it is to first divide 3 by 4 and then add 5;
Error : the programmer codes to add 5 and 3 first and then
divides the result ( calculation is not doone as mentioned
in the req )
Bug: programmer understands but declares the variable
differently ie in this case, it must be double or float
but declares it as int.
