## Conditional Operator
|
||
|
|
|
||
|
|
Conditional operator is a ternary operator, that is it needs 3 operands.
|
||
|
|
Conditional operator is used to replace a simple if-else statements.
|
||
|
|
|
||
|
|
Syntax :
|
||
|
|
```cpp
|
||
|
|
(condition)?(expression-1):(expression-2);
|
||
|
|
```
|
||
|
|
Here, expression-1 is evaluated when condition is true and expression-2 is evaluated when condtion is false.
|
||
|
|
Similar if-else statement would be :
|
||
|
|
```cpp
|
||
|
|
if(condition)
|
||
|
|
{
|
||
|
|
expression-1;
|
||
|
|
}
|
||
|
|
else
|
||
|
|
{
|
||
|
|
expression-2;
|
||
|
|
}
|
||
|
|
```
|
||
|
|
Hence conditional operator is very handy when you need to write simple if-else statement. It can also be used in #define
|
||
|
|
preprocessor when similar condition is to be used in multiple places.
|
||
|
|
|
||
|
|
For example, to find maximum of two number conditional operator can be used as follows :
|
||
|
|
|
||
|
|
```cpp
|
||
|
|
#define big(a,b) (a>=b)?a:b
|
||
|
|
|
||
|
|
int maximum,x=5,y=6; // variable to store maximum of two numbers
|
||
|
|
maximum=(x>y)?x:y; // directly using conditional operator
|
||
|
|
maximum=big(x,y); // using the #define preprocessor defined above as big
|
||
|
|
```
|
||
|
|
**Good Luck to all of you**
