The ability to convert analog quantities as described by an electrical signal to a digital quantity electrical counterpart is important. This procedure is referred to as analog-to-digital (ADC) and digital-to-analog (DAC). These conversions are readily performed by integrated circuits (chip technology). Coding and decoding of digital quantities as well as storing and recalling these digital quantities (numbers) are signi cant features in our computerized world.

of the error estimate and, perhaps more importantly, an extra factor of k in the denominator.] EXAMPLE 8.29

Here, fp is a variable of type FILE *. However, you usually see it written like this:

cout << *p << " "; p++; } return 0; }

In the preceding chapters, several Try This examples have developed and evolved a queue class as a means of illustrating several fundamental C# programming concepts, such as encapsulation, properties, exceptions, and so on. Although creating your own data structures, such as a queue, is a good way to learn about C#, it is not something that you will normally need to do. Instead, you will usually use one of the standard collections. In the case of a queue, this is Queue<T>. It provides a high-performance implementation that is fully integrated into the overall Collections framework. In this section, the final Try This in the book, you will see how to put Queue<T> into action. It creates a short program that simulates using a queue to grant users access to a network. Queue<T> is a dynamic collection that grows as needed to accommodate the elements it must store. Queue<T> defines the following constructors: public Queue( ) public Queue (int capacity) public Queue (IEnumerable<T> c) The first form creates an empty queue with an initial default capacity. The second form creates an empty queue with the initial capacity specified by capacity. The third form creates a queue that contains the elements of the collection specified by c. In addition to the functionality defined by the collection interfaces that it implements, Queue<T> defines the methods shown here. To put an object in the queue, call Enqueue( ). To remove and return the object at the front of the queue, call Dequeue( ). An InvalidOperationException is thrown if you call Dequeue( ) when the invoking queue is empty. You can use Peek( ) to return, but not remove, the next object.
