C# Conditional (Ternary) Operator

The conditional (ternary) operator in C# is a shorthand for the if-else statement. It evaluates a condition and returns one of two expressions based on whether the condition is true or false.

Key Topics

Syntax

The syntax for the conditional (ternary) operator is:

condition ? trueExpression : falseExpression;

Example: Conditional (Ternary) Operator

int a = 5;
int b = 10;
string result = (a > b) ? "a is greater" : "b is greater";
Console.WriteLine(result);

Output:

b is greater

Code Explanation: The ternary operator checks if a is greater than b. Since it is not, the expression returns "b is greater".
