// ---------------- Syntax of Ternary Operators ----------------- //

string stateOfMatter;
int temperature = 23;


// ---- For just one condition ---- //
stateOfMatter = temperature < 0 ? "Solid": "Liquid";
  
// If temperature is below zero, then stateOfMatter is solid, otherwise
// it will be liquid
  
  
// ---- For more conditions ---- //
stateOfMatter = temperature < 0 ? "Solid" : (temperature > 100 ? "Gas" : "Liquid");

Example 2: conditonal statements c sharp online

var rand = new Random();
var condition = rand.NextDouble() > 0.5;

var x = condition ? 12 : (int?)null;

Example 3: c# ternary operator

double sinc(double x) => x != 0.0 ? Math.Sin(x) / x : 1;

Console.WriteLine(sinc(0.1));
Console.WriteLine(sinc(0.0));
// Output:
// 0.998334166468282
