c# ternary
// ---------------- 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");c# ternary operator
/* In C#, if condition is true, the first expression is evaluated and becomes
the result; if false, the second expression is evaluated and becomes
the result. */
// The syntax of ternary operator is:
Condition ? Expression1 : Expression2;
// Here is a simple example:
string color = "blue";
string result = (color == "blue") ? "blue" : "NOT blue";
Console.WriteLine(result);
// Here is a really good diagram of the ternary operator:
// https://www.codebuns.com/wp-content/uploads/2018/09/ternary-operator.png
// The normal if else statment is the same as the ternary operator.
// If else statement:
if (number % 2 == 0)
{
isEven = true;
}
else
{
isEven = false;
}
// Ternary operator:
isEven = (number % 2 == 0) ? true : false ;
// Another example use of the ternary operator:
class Ternary
{
public static void Main(string[] args)
{
int number = 2;
bool isEven;
isEven = (number % 2 == 0) ? true : false ;
Console.WriteLine(isEven);
}
} // OUTPUT: Truec# 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

static void Sample(string input)
{
string result = input == null ? "default" : input;
Console.WriteLine($"Result: {result}");
