Complex if statement using ?: Operator in C

Question

Is it possible to write the equivalent expression "if" using "?" operator in C? I want to write the expression "if-else if-else" and it was interesting, can I use "?" Operator.

I find the regular syntax to use is "?" will be something like

foo = (bar == 42) ? answerToEverything : useless;

If I wanted to rewrite the next statement on the same line using "?" operator, can i do this? How?

if(bar == 42) {
  foo = answerToEverything;
} 
else if(bar == 23) {
  foo = bigMike;
} 
else foo = useless;

Answer 1

foo = 
    (bar == 42) ? answerToEverything :
    (bar == 23) ? bigMike :
    useless;

Answer 2

Yes you can, but it's ugly and hard to understand!

if (bar == 42) {
  foo = answerToEverything;
} else if (bar == 23) {
  foo = bigMike;
} else {
  foo = useless;
}

, , :

foo = (bar == 42)
  ? answerToEverything
  : (bar == 23)
      ? bigMike
      : useless;
