==Use format commands: indicate the parameter sequence==

<source lang="csharp">using System;

class Example {

==Use the C format specifier to output dollars and cents.==

<source lang="csharp">using System;

class Example {
public static void Main() {
decimal price;
decimal discount;
decimal discounted_price;

price = 19.95m;
discount = 0.15m;

discounted_price = price - ( price * discount);

Console.WriteLine("Discounted price: {0:C}", discounted_price);
}
}</source>
<pre class=codeResult>Discounted price: $16.96</pre>
