Conditional operator in C (?:)
- It is a ternary operator.
- The operator is ?:
- It acts on three operands to give the answer.
The syntax for using the ternary operator is
y = a? b : c;
where ‘a’, ‘b’ and ‘c’ are operands.
y = b, if ‘a’ is TRUE.
y = c, if ‘a’ is FALSE.
You may also refer to the video posted at the end of this page.
Examples:
y = (4>2) ? 4 : 2;
Evaluate (4>2), since 4>2 is Ture, we take the value written in between ? and : and that is 4.
So, y = 4
y = 0==0 ? 1 : 0;
Evaluate (0==0), since 0==0 is Ture, we take the value written in between ? and : and that is 1.
So, y = 1
y = 4!=4? 1 : 0
Evaluate (4!=4), since 4!=4 is False, we take the value written after “:” and that is 0.
So, y = 0
