Operators

Arithmetic (+ - * /), comparison (== != > <), and logical (&& || !) operators work as in most C-family languages.

Example: a boolean expression, interpolated into output

using System;

class Program {
    static void Main() {
        int score = 85;
        bool passed = score >= 50 && score <= 100;
        Console.WriteLine($"Passed: {passed}");
    }
}

Passed: True

Notice the capital True in the output — unlike C++ or Java, C# actually prints its boolean values as the words True/False directly, no ternary trick needed. The $"..." syntax is a C# string interpolation, letting {passed} be evaluated and inserted directly — the same underlying idea as Python's f-strings or JavaScript's template literals, just C#'s particular spelling of it.
