If an integer is positive or negative

[deepankarrawat]

How will i know in C programming if an integer is negative or positive?

[RedSon]

If it is greater than zero it will be positive and if it is less than zero it will be negative.

Please provide some details. What exactly is your question?

... you ask the program?

... the first bit of the integer will be set if it is negative. If it is not set, the number is non-negative. If the integer is zero, none of the bits will be set.

I think mine is the best answer. I'm choosing it, because I'm awesome!

... the first bit of the integer will be set if it is negative. If it is not set, the number is non-negative ...

This is only true if signed integers are encoded using two's-complement. Although two's-complement is ubiquitous, it is not mandated by the C Standard. This approach is not portable.

Oooh don throws a right hook at jkm!! Will he parry or duck?

He may be down for the count folks!
