The Conditional Expression Operator

An alternate method to using a simple if-else construct is the conditional expressions operator, ?:

A conditional expression operator is a ternary operator, it has three operand, whose general format is:

expression1 ? expression2 : expression3

Here the expression1 is evaluated first, if it is true then the expression 2 is the value of the conditional operator, otherwise the expression 3 is the value.

e.g.

                The if else construct

if(a>b)

 {

z = a;

 }

else

 {

                z = b;

                       }

                This can be written as

                                z = (a>b) ? a: b;
