Ternary Operator

Question

What one can learn from ternary operator? Because in1>n2 and n1<n2 are giving different output. An example program is given. Problem is highlighted.

using System;
class Program
{
static void Main(string[] args)
{
int n1, n2;
n1 = 10;
n2 = 20;

int max = (n1 > n2) ? n1 : n2;
Console.WriteLine(max);//20

int min = (n1 < n2) ? n1 : n2;
Console.WriteLine(min);//10

Console.ReadKey();
}
}

The ternary operator tests a condition. It compares two values. It produces a third value that depends on the result of the comparison. This can be accomplished with if-statements or other constructs . The conditional operator ( ?: ) returns one of two values depending on the value of a Boolean expression. Following is the syntax for the conditional operator. The condition must evaluate to true or false . If condition is true  first_expression is evaluated and becomes the result. If condition is false  second_expression is evaluated and becomes the result. Only one of the two expressions is evaluated.

The ternary operator takes this general form: a ? b : c where 'a' is a bool expression and 'b' and 'c' are expessions of the same type. If 'a' is true the value is 'b'. If 'a' is false the value is 'c'. In the first example: int max = (n1 > n2) ? n1 : n2; 10 > 20 is false and so the value is n2 which is 20. In the second example: int min = (n1 10
