Hi to all. find out the biggest among two numbers without using any
conditional statements and any relational operators.

This cannot be done, not even by using non-portable
trickery. The reason is simple: there is no such thing
as the "biggest" of just two numbers. The superlative
form of an adjective implies three or more alternatives.

Had you written "bigger" the answer might have been
different -- but that would have made the question sound
like homework, and we can't have that, can we?

No, they don't. Check the OED. What you describe is merely customary in
some circles, but not the only correct usage.

So, how many open NNTP proxies do you have access to?

result=(x-y) //subtract y from x
//if x>y result is +ve else -ve

result=result >>31 //get the sign bit to last bit
result=result&0x01 //mask the last bit

return x*result + y*(~result & 0x1)

if result =1 x will be returned as ~result&0x1 would be 0

Why would the result be negative if the two values are equal?

This question has been beaten to death over the years. Try
searching the archives.

No thanks; I've got other uses for \$295.

"Some circles" meaning "Those who value English," I
guess ...

Does the OED list "irregardless?" Does it list "verb"
as a transitive verb? Does it endorse the sportscasters'
monstrous misuse of the present indicative for the subjunctive
("If I'm Alex Rodriguez I'm looking fast ball here")? We're
down to the old prescriptive vs. descriptive debate, and I for
one choose not use a description of other people's bad usage
as a prescription for my own. Harrumph!

It's simple as well as off topic (since it's not C specific):

max(x, y) = (x + y + |x - y|) / 2

That has so many portability problems I'm not going to bother to
decide whether it's correct.

We must do something. This is something. Therefore, we must do this.
