comparing numbers

[jerico]

Hi.How can the greatest of three numbers be determined without using the comparison operator?Thanks for any help.

Use the ternary operator (?:)

[Banfa]

max(a, max(b,c))

Of course that just hides the comparision operator in the standard header files

Hi Pukur. Could you show me how to use the ternary operator to get desired result?Thanks.

(condition)? e1:e2;

If the condition is true then e1 will be evaluated otherwise e2 will be evaluated.

Let us suppose that a,b,c are the three numbers and the statement for finding the maximum of these three is.....

max=(a>b)?((a>c)?a:c):((b>c)?b:c);

hi fellows,

jerico wondered how to get greatest of 3 numbers without using the comparison operator and I actually see three of them in this pukur123's statement:

max=(a>b)?((a>c)?a:c): ((b>c)?b:c);

well, here is my solution (works for unsigned integer values):

int getMax(unsigned a, unsigned b, unsigned c)
{
    int m=0;
    while((a?a--:0)+(b?b--:0)+(c?c--:0)) m++;
    return m;
}
