Which of the following is the correct usage of conditional operators used in C?
a>b ? c=30 : c=40;
a>b ? c=30;
max = a>b ? a>c?a:c:b>c?b:c
return (a>b)?(a:b)
Answer: Option
Explanation:

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.

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

Now I guess this statement is more clear.

Option C is also not correct because there is no semi colon in the end of the statement.
