Actually, ?: this indicates that conditional operator,we use this ?: as an alternative for if-else functions limitedly.

What is the difference between = and == operators? Please tell me.

I disagree with the answer because one can write nested ternary operators equating nested if else statements.

I think all four options are correct. because we can replace every if-else with ?: even nested ones also.

eg. if(a==5){

It can be replaced by.

return x>y?1:0;

It will work.

I think question is misprinted, first one is correct

Tell me a single example which cannot be converted.

We can't use return statements in ?: whereas we can use it in if else blocks.
So option D is true.

Can anyone please explain why the first option is incorrect?

Gayatri Walmik said:   7 years ago
We can use ?: for nested if else statements too. Like if (x>5? (x>10?x=1:x=2) :x=3).

What does it mean by multiple if else statements?

Nehal said:   7 years ago
One more thing that we cannot use return in conditional statement.

Option D is correct. Since there are some if statements which do not have any else part and they cannot be converted into ?: So 3 conditions are fulfilled but first condition is not fulfilled.
