The switch statement

DisplayMeasurement(-4);  // Output: Measured value is -4; out of an acceptable range.
DisplayMeasurement(50);  // Output: Measured value is 50.
DisplayMeasurement(132);  // Output: Measured value is 132; out of an acceptable range.

void DisplayMeasurement(int measurement)
{
    switch (measurement)
    {
        case < 0:
        case > 100:
            Console.WriteLine($"Measured value is {measurement}; out of an acceptable range.");
            break;
        
        default:
            Console.WriteLine($"Measured value is {measurement}.");
            break;
    }
}
