Question

Which of the following is the correct usage of conditional operators used in C?


Options:
A .  a>b ? c=30 : c=40;
B .  a>b ? c=30;
C .  max = a>b ? a>c?a:c:b>c?b:c
D .  return (a>b)?(a:b)
Answer: Option C

Option A: assignment statements are always return in paranthesis in the case of conditional 

operator. It should be a>b? (c=30):(c=40);

Option B: it is syntatically wrong.

Option D: syntatically wrong, it should be return(a>b ? a:b);

Option C: it uses nested conditional operator, this is logic for finding greatest number out of 

three numbers.
