Ternary Operator in C#

Ternary operator:-

The Ternary operator is not a type of conditional statement but it is also used to check the conditions. It returns only one value based on conditions. Use the ternary operator to check many values in a single line of coding.

Syntax:-

Variable = condition ? True Part : False Part;

Conditional Operator:-

The conditional operator (?:) returns one of two values depending on the value of a Boolean expression. Following is the syntax for the conditional operator.

Syntax:-

Variable = condition ? first_expression : second_expression;

Source Code :-

static void Main(string[] args)

{

int a, b, Value;

a = 100;

b = 50;

Value = a > b ? a : b ;

Console.WriteLine("Greater Value:" + Value);

Console.Read();

}

Output:-

Greater Value:100
