Another conditional statement, nested question

Question

According to the priority tables C, the ternary conditional operator has the right to left associativity.

So, does it directly convert to the equivalent if-else ladder?

For example, Maybe:

x?y?z:u:v;

just interpreted as:

if(x)
{
   if(y)
   { z; }
   else
   { u; }
}
else
{ v; }

matching else (:) with the nearest unpaired if (?)? Or does associativity from right to left imply some other arrangement?

Answer 1

The example you gave can only be interpreted in one way (for example, using if statements) whether the triple operator has right-to-left or left-to-right right-handedness.

If a right-to-left relationship matters when you have:

x = a ? b : c ? d : e;

: x = a ? b : (c ? d : e), x = (a ? b : c) ? d : e.

:

int getSign(int x) {
    return x<0 ? -1 :
           x>0 ?  1 :
                  0;
}

(, ) if/else-if:

int getSign(int x) {
    if (x<0)
        return -1;
    else if (x>0)
        return 1;
    else
        return 0;
}
