TERNARY OPERATOR

Introduction

Ternary operators return values based on the outcomes of relational expressions. For example, if you want to return the value of 1 if the expression is true and 2 if it is false, you can use the ternary operator.

Program/Example

If you want to assign the maximum values of i and j to k then you can write the statement

k = ( i>j ) ? i : j; 

If i > j then k will get the value equal to i, otherwise it will get the value equal to j.

The general form of the ternary operator is:

(expr 1) ? expr2 : expr3 

If expr1 returns true then the value of expr2 is returned as a result; otherwise the value of expr3 is returned.
