Re: Subtract smaller or larger number from x?

I have a number x. I would now like to find the difference between this
number x and another number y.

But y can be either larger or smaller than x. Currently I check if the
number y is greater or smaller than x:

int diff; // the difference between x and y

if (y > x){
diff = y-x;
}else{
diff = x-y;
}

is there not a more elegant way to do this when I would like the
difference to be a positive value??

Yes, of course
As my sis pointed out it would be more efficient if you take the
absolute value of the differenc, like this:

int diff; // the difference between x and y

{ diff = abs(x-y); // abs is the absolute value function
}
