### Conditional Operators ?

The conditional operator is an operator used in C and C++ as well as in other languages also, operator returns one of two values depending on the result of an expression.

### Syntax of Conditional Operator ?

`(expression 1) ? expression 2 : expression 3`

`If expression 1 evaluates to true, then expression 2 is evaluated.(or)If expression 1 evaluates to false, then expression 3 is evaluated instead.`

### Conditional Operators

Operator Description Example
- Subtraction a-b
* Multiplication a*b
/ Division a/b
% Modulus a%b

### Example 1:

`#define MAX(a, b) (((a) > (b)) ? (a) : (b))`

#define MAX(a, b) (((a) > (b)) ? (a) : (b))
In this example, the expression`a > b` is evaluated. If it evaluates to true then a is returned. If it evaluates to false, b is returned. Therefore, the line `MAX(4, 12);` evaluates to 12.

### Output:

` result of x: 40`

### Output:

```First run:
Enter year: 2000
2000 is Leap year.

Second run:
Enter year: 2017
2017 is not a Leap year.

Third run:
Enter year: 1900
1900 is not a Leap year.

Fourth run:
Enter year: 2016
2016 is Leap year.
```

### Output:

```Enter year (ENTER 0 for exit...): 2000
2000 is Leap year.

Enter year (ENTER 0 for exit...): 2017
2017 is not a Leap year.

Enter year (ENTER 0 for exit...): 1900
1900 is not a Leap year.

Enter year (ENTER 0 for exit...): 2016
2016 is Leap year.

Enter year (ENTER 0 for exit...): 0
0 is Leap year.```
