Invoice and Numeric Formatting
Format aligned currency output with interpolation.
Introduction
C# composite formatting makes console reports readable without manual padding.
Alignment components set field widths and the C format specifier uses the current culture's currency format.

foreach (var (name, quantity, price) in lines)
Console.WriteLine($"{name,-8} {quantity,2} {quantity * price,8:F2}");
}
