Thread: me can't think

Say you had a vector with some +ve ints and some -ve ints, how do you return the one which is closest to 0???

What's a +ve and -ve int?

vector meaning std::vector, or vector meaning those things in physics?

Code:

#define ABS(x) ((x) < 0 ? -(x) : (x))

int GetClosestToZero(void)
{
    int closest = myVector[0];
    for(int i = 1; i < myVector.size(); i++)
    {
        if(ABS(myVector[i]) < ABS(closest))
        {
            closest = myVector[i];
        }
    }
    return(closest);
}

I haven't compiled this code, it's designed to give you an idea of the kind of thing you should be doing. It assumes there is at least one value in myVector.

U.

+ve = positive
-ve = negative

As someone has already asked, can you please clarify what you mean by 'vector'?

Do you mean the mathematical construct (a one dimensional matrix) or do you mean std::vector??

std::vector that one

+ve = POSITIVE
-ve = NEGATIVE

or just read previous thread
