Hi can any one tell me if diff data types like int and short be
multiplied
in code.
i HAVE TO REDUCE THE MEMORY SIZE SO CHANGE DATATYPE OF nbr TO SHORT
WHERE ELSE DO I MAKE CHANGES.ALSO IF DATA TYPE OF NBR IS CHNGED CAN IT
BE MUTLIPLIED WITH SEN AND N WITHOUT CHANGING DERE DATATYPE
HELP ITS URGENT
THANK U

Hs
thanx for the reply but i didn gt it there.
Its like should i make the chnges ever where in the code where i hav
used
nbr
?
wat about the part where nbr is multiplied or compared with other data
type int?
plz help
thank you

You have to (so urgently) deal with performance optimizations/
refactorings without knowledge how int and short work together? Sounds
like either nonsense or homework. If it is nonsense then tell to
people who asked it from you that you are not qualified enough. If it
is homework then do it yourself? Search for "integral promotions" and
"implicit conversions" in documentation or net.

Hey, come on. He's changing the type of "nbr", which is int[3][3][3],
to short[3][3][3]. Those 54 bytes are vital!!!
